Well-known SED command to extract a first line and print to another file
sed -n '1 p' /p/raw.txt | cat >> /p/001.txt ;
gives an output in /p/001.txt like
John Doe
But how to modify this command above to add some free text and have, for example, the output like
Name: John Doe
Thanks for any hint to try.
You can do that in a single command (and no sub-shells):
sed 's/^/Name: /;q' /p/raw.txt >> /p/001.txt
This prefixes "Name: " in front of the first line, prints it, then quits so you don't process additional lines. Add a line number before the q to print all lines up to (and including) that number. The output is appended to /p/001.txt just like your original code.
If you want a range of lines:
sed -n '3,9{s/^/Name: /;p}9q' /p/raw.txt >> /p/001.txt
This reads from lines 3-9, performs the substitution, prints, then quits after line 9.
If you want specific lines, I recommend awk:
awk 'NR==3 || NR==9 { print "Name: " $0 } NR>=9 { exit }' /p/raw.txt >> /p/001.txt
This has two clauses. One says the number of record (line number) is either 3 or 9, in which case we print the prefix and the line. The other tells us to stop reading the file after the 9th record.
Here are two more commands to show how awk can act on just the first line(s) or a given range:
awk '{ print "Name: " $0 } NR >= 1 { exit }' /p/raw.txt >> /p/001.txt
awk '3 <= NR { print "Name: " $0 } NR >= 9 { exit }' /p/raw.txt >> /p/001.txt
It appears you're continuously building one file from the other. Consider:
tail -Fn0 /p/raw.txt |sed 's/^/Name: /' >> /p/001.txt
This will run continuously, adding only new entries (added after the command is run) to /p/001.txt
Perhaps you have lots of duplicates to resolve?
awk 'NR != FNR { $0 = "Name: " $0 } !s[$0]++' \
/p/001.txt /p/raw.txt > /tmp/001.txt && mv /tmp/001.txt /p/001.txt
This folds together the previously saved names with any new names, printing names only once (!s[$0]++ is true when s[$0] is zero (its default state), but after the evaluation, it increments to one, making it false on the second occurrence. When a bare clause has no action, the line is printed.) Because we're reading the output file, we need a temporary output. Upon its successful completion, we then move it atop the target output file.
printf "Name : %s\n" "$(sed -n '1p;q' /p/raw.txt)" >/p/001.txt
should do it. If sed is not a requirement do
echo -e "Name : $(sed -n '1p;q' /p/raw.txt)" >/p/001.txt
Note
The q option with the sed quits it without processing any more commands or input.
The -e option tells echo to interpret escape sequences. This is a peculiarity of bash shell.
Say I have a file like so:
+jaklfjdskalfjkdsaj
fkldsjafkljdkaljfsd
-jslakflkdsalfkdls;
+sdjafkdjsakfjdskal
I only want to find and count the amount of times during this file a line that starts with - is immediately followed by a line that starts with +.
Rules:
No external scripts
Must be done from within a bash script
Must be inline
I could figure out how to do this in a Python script, for instance, but I've never had to do something this extensive in Bash.
Could anyone help me out? I figure it'll end up being grep, perl, or maybe a talented sed line -- but these are things I'm still learning.
Thank you all!
grep -A1 "^-" $file | grep "^+" | wc -l
The first grep finds all of the lines starting with -, and the -A1 causes it to also output the line after the match too.
We then grep that output for any lines starting with +. Logically:
We know the output of the first grep is only the -XXX lines and the following lines
We know that a +xxx line cannot also be a -xxx line
Therefore, any +xxx lines must be following lines, and should be counted, which we do with wc -l
Easy in Perl:
perl -lne '$c++ if $p and /^\+/; $p = /^-/ }{ print $c' FILE
awk one-liner:
awk -v FS='' '{x=x sprintf("%s", $1)}END{print gsub(/-\+/,"",x)}' file
e.g.
kent$ cat file
+jaklfjdskalfjkdsaj
fkldsjafkljdkaljfsd
-jslakflkdsalfkdls;
+sdjafkdjsakfjdskal
-
-
-
+
-
+
foo
+
kent$ awk -v FS='' '{x=x sprintf("%s", $1)}END{print gsub(/-\+/,"",x)}' file

Another Perl example. Not as terse as choroba's, but more transparent in how it works:
perl -e'while (<>) { $last = $cur; $cur = $_; print $last, $cur if substr($last, 0, 1) eq "-" && substr($cur, 0, 1) eq "+" }' < infile
Output:
-jslakflkdsalfkdls;
+sdjafkdjsakfjdskal
Pure bash:
unset c p
while read line ; do
[[ $line == +* && $p == 0 ]] && (( c++ ))
[[ $line == -* ]]
p=$?
done < FILE
echo $c
I have a file, xx.txt, like this.
1PPYA
2PPYB
1GBND
1CVHA
The first line of this file is "1PPYA". I would like to
Read the last character of "1PPYA." In this example, it's "A/"
Find "1PPY.txt" (the first four characters) from the "yy" directory.
Delete the lines start with "csh" which contain the "A" character.
Given the following "1PPY.txt" in the "yy" directory:
csh 1 A 1 27.704 6.347
csh 2 A 1 28.832 5.553
csh 3 A 1 28.324 4.589
csh 4 B 1 27.506 3.695
csh 5 C 1 29.411 4.842
csh 6 A 1 28.378 4.899
The required output would be:
csh 4 B 1 27.506 3.695
csh 5 C 1 29.411 4.842
Assuming your shell is bash
while read word; do
if [[ $word =~ ^(....)(.)$ ]]; then
filename="yy/${BASH_REMATCH[1]}.txt"
letter=${BASH_REMATCH[2]}
if [[ -f "$filename" ]]; then
sed "/^csh.*$letter/d" "$filename"
fi
fi
done < xx.txt
As you've tagged the question with awk:
awk '{
filename = "yy/" substr($1,1,4) ".txt"
letter = substr($1,5)
while (getline < filename)
if (! match($0, "^csh.*" letter))
print
close(filename)
}' xx.txt
This might work for you:
sed 's|^ *\(.*\)\(.\)$|sed -i.bak "/^ *csh.*\2/d" yy/\1.txt|' xx.txt | sh
N.B. I added a file backup. If this is not needed amend the -i.bak to -i
You can use this bash script:
while read f l
do
[[ -f $f ]] && awk -v l=$l '$3 != l' $f
done < <(awk '{len=length($0);l=substr($0,len);f=substr($0,0,len-1);print "yy/" f ".txt", l;}' xx.txt)
I posted this because you are a new user, however it will be much better to show us what you have tried and where you're stuck.
TXR:
#(next "xx.txt")
#(collect)
#*prefix#{suffix /./}
# (next `yy/#prefix.txt`)
# (collect)
# (all)
#{whole-line}
# (and)
# (none)
#shell #num #suffix #(skip)
# (end)
# (end)
# (do (put-string whole-line) (put-string "\n"))
# (end)
#(end)
Run:
$ txr del.txr
csh 4 B 1 27.506 3.695
csh 5 C 1 29.411 4.842
txr: unhandled exception of type file_error:
txr: (del.txr:5) could not open yy/2PPY.txt (error 2/No such file or directory)
Because of the outer #(collect)/#(end) (easily removed) this processes all of the lines from xx.txt, not just the first line, and so it blows up because I don't have 2PPY.txt.
I have a ~23000 line SQL dump containing several databases worth of data. I need to extract a certain section of this file (i.e. the data for a single database) and place it in a new file. I know both the start and end line numbers of the data that I want.
Does anyone know a Unix command (or series of commands) to extract all lines from a file between say line 16224 and 16482 and then redirect them into a new file?
sed -n '16224,16482p;16483q' filename > newfile
From the sed manual:
p -
Print out the pattern space (to the standard output). This command is usually only used in conjunction with the -n command-line option.
n -
If auto-print is not disabled, print the pattern space, then, regardless, replace the pattern space with the next line of input. If
there is no more input then sed exits without processing any more
commands.
q -
Exit sed without processing any more commands or input.
Note that the current pattern space is printed if auto-print is not disabled with the -n option.
and
Addresses in a sed script can be in any of the following forms:
number
Specifying a line number will match only that line in the input.
An address range can be specified by specifying two addresses
separated by a comma (,). An address range matches lines starting from
where the first address matches, and continues until the second
address matches (inclusively).
sed -n '16224,16482 p' orig-data-file > new-file
Where 16224,16482 are the start line number and end line number, inclusive. This is 1-indexed. -n suppresses echoing the input as output, which you clearly don't want; the numbers indicate the range of lines to make the following command operate on; the command p prints out the relevant lines.
Quite simple using head/tail:
head -16482 in.sql | tail -258 > out.sql
using sed:
sed -n '16224,16482p' in.sql > out.sql
using awk:
awk 'NR>=16224&&NR<=16482' in.sql > out.sql
You could use 'vi' and then the following command:
:16224,16482w!/tmp/some-file
Alternatively:
cat file | head -n 16482 | tail -n 258
EDIT:- Just to add explanation, you use head -n 16482 to display first 16482 lines then use tail -n 258 to get last 258 lines out of the first output.
There is another approach with awk:
awk 'NR==16224, NR==16482' file
If the file is huge, it can be good to exit after reading the last desired line. This way, it won't read the following lines unnecessarily:
awk 'NR==16224, NR==16482-1; NR==16482 {print; exit}' file
awk 'NR==16224, NR==16482; NR==16482 {exit}' file
perl -ne 'print if 16224..16482' file.txt > new_file.txt
People trying to wrap their heads around computing an interval for the head | tail combo are overthinking it.
Here's how you get the "16224 -- 16482" range without computing anything:
cat file | head -n +16482 | tail -n +16224
Explanation:
The + instructs the head/tail command to "go up to / start from" (respectively) the specified line number as counted from the beginning of the file.
Similarly, a - instructs them to "go up to / start from" (respectively) the specified line number as counted from the end of the file
The solution shown above simply uses head first, to 'keep everything up to the top number', and then tail second, to 'keep everything from the bottom number upwards', thus defining our range of interest (with no need to compute an interval).
Standing on the shoulders of boxxar, I like this:
sed -n '<first line>,$p;<last line>q' input
e.g.
sed -n '16224,$p;16482q' input
The $ means "last line", so the first command makes sed print all lines starting with line 16224 and the second command makes sed quit after printing line 16428. (Adding 1 for the q-range in boxxar's solution does not seem to be necessary.)
I like this variant because I don't need to specify the ending line number twice. And I measured that using $ does not have detrimental effects on performance.
# print section of file based on line numbers
sed -n '16224 ,16482p' # method 1
sed '16224,16482!d' # method 2
cat dump.txt | head -16224 | tail -258
should do the trick. The downside of this approach is that you need to do the arithmetic to determine the argument for tail and to account for whether you want the 'between' to include the ending line or not.
sed -n '16224,16482p' < dump.sql
Quick and dirty:
head -16428 < file.in | tail -259 > file.out
Probably not the best way to do it but it should work.
BTW: 259 = 16482-16224+1.
I wrote a Haskell program called splitter that does exactly this: have a read through my release blog post.
You can use the program as follows:
$ cat somefile | splitter 16224-16482
And that is all that there is to it. You will need Haskell to install it. Just:
$ cabal install splitter
And you are done. I hope that you find this program useful.
Even we can do this to check at command line:
cat filename|sed 'n1,n2!d' > abc.txt
For Example:
cat foo.pl|sed '100,200!d' > abc.txt
Using ruby:
ruby -ne 'puts "#{$.}: #{$_}" if $. >= 32613500 && $. <= 32614500' < GND.rdf > GND.extract.rdf
I wanted to do the same thing from a script using a variable and achieved it by putting quotes around the $variable to separate the variable name from the p:
sed -n "$first","$count"p imagelist.txt >"$imageblock"
I wanted to split a list into separate folders and found the initial question and answer a useful step. (split command not an option on the old os I have to port code to).
Just benchmarking 3 solutions given above, that works to me:

Sorry guys!
My analysis above ends up being an example of a basic flaw in doing an analysis.
The flaw is not knowing in depth the resources used for the analysis.
In this case, I used a log file to analyze the performance of a search for a certain number of lines within it.
Using 3 different techniques, searches were made at different points in the file, comparing the performance of the techniques at each point and checking whether the results varied depending on the point in the file where the search was made.
My mistake was to assume that there was a certain homogeneity of content in the log file.
The reality is that long lines appear more frequently at the end of the file.
Thus, the apparent conclusion that longer searches (closer to the end of the file) are better with a given technique, may be biased. In fact, this technique may be better when dealing with longer lines. What remains to be confirmed.
I was about to post the head/tail trick, but actually I'd probably just fire up emacs. ;-)
esc-x goto-line ret 16224
mark (ctrl-space)
esc-x goto-line ret 16482
esc-w
open the new output file, ctl-y
save
Let's me see what's happening.
I would use:
awk 'FNR >= 16224 && FNR <= 16482' my_file > extracted.txt
FNR contains the record (line) number of the line being read from the file.
Using ed:
ed -s infile <<<'16224,16482p'
-s suppresses diagnostic output; the actual commands are in a here-string. Specifically, 16224,16482p runs the p (print) command on the desired line address range.
I wrote a small bash script that you can run from your command line, so long as you update your PATH to include its directory (or you can place it in a directory that is already contained in the PATH).

This might work for you (GNU sed):
sed -ne '16224,16482w newfile' -e '16482q' file
or taking advantage of bash:
sed -n $'16224,16482w newfile\n16482q' file
Since we are talking about extracting lines of text from a text file, I will give an special case where you want to extract all lines that match a certain pattern.
myfile content:
=====================
line1 not needed
line2 also discarded
[Data]
first data line
second data line
=====================
sed -n '/Data/,$p' myfile
Will print the [Data] line and the remaining. If you want the text from line1 to the pattern, you type: sed -n '1,/Data/p' myfile. Furthermore, if you know two pattern (better be unique in your text), both the beginning and end line of the range can be specified with matches.
sed -n '/BEGIN_MARK/,/END_MARK/p' myfile
I've compiled some of the highest rated solutions for sed, perl, head+tail, plus my own code for awk, and focusing on performance via the pipe, while using LC_ALL=C to ensure all candidates at their fastest possible, allocating 2-second sleep gap in between.
The gaps are somewhat noticeable :

The -n in the accept answers work. Here's another way in case you're inclined.
cat $filename | sed "${linenum}p;d";
This does the following:
pipe in the contents of a file (or feed in the text however you want).
sed selects the given line, prints it
d is required to delete lines, otherwise sed will assume all lines will eventually be printed. i.e., without the d, you will get all lines printed by the selected line printed twice because you have the ${linenum}p part asking for it to be printed. I'm pretty sure the -n is basically doing the same thing as the d here.
I was looking for an answer to this but I had to end up writing my own code which worked. None of the answers above were satisfactory.
Consider you have very large file and have certain line numbers that you want to print out but the numbers are not in order. You can do the following:
My relatively large file
for letter in {a..k} ; do echo $letter; done | cat -n > myfile.txt
1 a
2 b
3 c
4 d
5 e
6 f
7 g
8 h
9 i
10 j
11 k
Specific line numbers I want:
shuf -i 1-11 -n 4 > line_numbers_I_want.txt
10
11
4
9
To print these line numbers, do the following.
awk '{system("head myfile.txt -n " $0 " | tail -n 1")}' line_numbers_I_want.txt
What the above does is to head the n line then take the last line using tail
If you want your line numbers in order, sort ( is -n numeric sort) first then get the lines.
cat line_numbers_I_want.txt | sort -n | awk '{system("head myfile.txt -n " $0 " | tail -n 1")}'
4 d
9 i
10 j
11 k
Maybe, you would be so kind to give this humble script a chance ;-)
#!/usr/bin/bash
# Usage:
# body n m|-m
from=$1
to=$2
if [ $to -gt 0 ]; then
# count $from the begin of the file $to selected line
awk "NR >= $from && NR <= $to {print}"
else
# count $from the begin of the file skipping tailing $to lines
awk '
BEGIN {lines=0; from='$from'; to='$to'}
{++lines}
NR >= $from {line[lines]=$0}
END {for (i = from; i < lines + to + 1; i++) {
print line[i]
}
}'
fi

You could use sed command in your case and is pretty fast.
As mentioned lets assume the range is: between 16224 and 16482 lines
#get the lines from 16224 to 16482 and prints the values into filename.txt file
sed -n '16224 ,16482p' file.txt > filename.txt
#Additional Info to showcase other possible scenarios:
#get the 16224 th line and writes the value to filename.txt
sed -n '16224p' file.txt > filename.txt
#get the 16224 and 16300 line values only and write to filename.txt.
sed -n '16224p;16300p;' file.txt > filename.txt
