How to force echo command to output a tab character in MS nmake makefile?
Verbatim tabs inserted right into a string after echo command are removed by nmake and don't show up in the output file.
all :
#echo I WANT TO OUTPUT THE <TAB> CHARACTER HERE! > output.txt
You can use a variable with TAB char. Put this lines in your .bat file:
set tab=[stroke TAB char from your keyboard]
echo a%tab%b>yourfile.txt
Doing so, yourfile.txt will have text a[TAB]b
As a workaround, you can create a file containing the tab character, named input.txt (not using nmake), and then say:
all :
#copy /b input.txt output.txt
I assume you already have tried to put the tab inside quotes?
all:
#echo "<TAB>" > output.txt
DOS and Windows have ugly text support in native batch files :).
Here is nice way to do your task:
install Python interpretator
write simple script which appends character with specified code to file
call script wherever you want :)
Simple script:
'''
append_char.py - appends character with specified code to end of file
Usage: append_char.py filename charcode
'''
import os
import sys
filename = sys.argv[1]
assert os.path.exists(filename)
charcode = int(sys.argv[2])
assert 0 <= charcode <= 255
fh = open(filename, 'ab')
fh.seek(0, os.SEEK_END)
fh.write(chr(charcode))
fh.close()
using this script from batch file you can create any possible file in universe :)
output.txt:
<<output.txt
I WANT TO OUTPUT THE <TAB> CHARACTER HERE!
<<KEEP
<TAB> represents a literal tab character here of course.
I had the same need. I used the answer using the quotes around the character and just took it one step further.
{tab} means pressing the keyboard tab key in the text editor.
SET tab="{tab}"
SET tab=%tab:~1,1%
The second line extracts the middle character from the quoted string.
Now you can use the %tab% variable with ECHO and, I suspect, anywhere else it's needed.
ECHO %tab%This text is indented, preceded by a tab.
I suspect this technique could be used with other problem characters as well.

I need to replace 400+ words with different hyperlinks in a rtf- or .docx-document.
I’ve made a script using keystrokes (cmd+f, esc etc), but the script takes forever and is not stable enough.
Using sed -i I’m able to do a replacement of the word, but not with hyperlink. Is this possible?
set theFile to choose file
set original to "foo"
set substitute to "VG"
set newlink to "https://www.vg.no"
do shell script "sed -i '' \"s|" & original & "|" & substitute & "|g\" " & quoted form of (POSIX path of theFile)
Here is something specific to try:
First, create a rich text document with the word 'foo' as its content (in TextEdit, as Word's output is an abomination). Save the file in the appropriate place and run this:
set theFile to ((path to desktop) as text) & "slink3.rtf"
set qptf to quoted form of POSIX path of theFile
set origStr to "foo"
set subStr to "VG"
set newlink to "https://www.vg.no"
do shell script "sed -i '' -e 's|" & origStr & "|" & subStr & "|' -e 's|VG|{{\\\\*\\\\fldinst{HYPERLINK \"https://www.vg.no/\"}}{\\\\fldrslt VG}}|' " & qptf
This expands to:
do shell script "sed -i '' -e 's|foo|VG|' -e 's|VG|{{\\\\*\\\\fldinst{HYPERLINK \"https://www.vg.no/\"}}{\\\\fldrslt VG}}|' '/Users/username/Desktop/slink3.rtf'"
The actual shell command which runs is:
% sed -i '' -e 's|foo|VG|' -e 's|VG|{{\\*\\fldinst{HYPERLINK "https://www.vg.no/"}}{\\fldrslt VG}}|' '/Users/username/Desktop/slink3.rtf'
What it does is first replace the string foo with the string VG, and then replace the string VG with VG as hyperlinked text.
NB TextEdit has a preference to display the raw rtf upon opening a file rather than the formatted text. If you do this with a document containing a single word, the structure is relatively clear. I recommend against even looking at a Word-generated document.
If you do this, you will see that the raw rtf uses a single backslash but both the shell and applescript require escaping which is why the script has \\\\.
Incidentally, I notice that you finish your sed search with 'g' but shouldn't this only run once per line? Consider removing it.
Obviously, I don't know your entire workflow but hopefully this matches the section you have posted.
I got about 300 (.txt) files in a folder with "normal text" formatted with /n's. I want all text in these files, to be in the first line, because a program in my pipeline requires that.
Exampel:
(IS:)
GTCGCAGCCG
TCGGCTCGGA
TCTCGGCCTC
(SHOULD BE:)
GTCGCAGCCGTCGGCTCGGATCTCGGCCTC
If I could overwrite them all, with file names staying the same, that would be convenient. I don't want to crack out python yet, is there an easy UNIX tool / command line approach?
I was here before:
How do I remove newlines from a text file?
But how to do that for all 300 files in my folder? If i use tr -d '\n' < *.txt it tells me: "bash: *.txt: ambiguous redirect"
You need a shell loop to process each file in turn. Note that ed is a better choice than tr, as it is designed to work with files, not streams.
for f in *.txt; do
printf '%%j\nwq\n' | ed "$f"
done
%j is the ed command to join all lines in the buffer; the %% is necessary here to make printf output a literal %. wq is the command to write changes back to the file and quite. (The q is optional, as ed will exit after the end of its script anyway.)
I have a huge list of locations in this form in a text file:
ar,casa de piedra,Casa de Piedra,20,,-49.985133,-68.914673
gr,riziani,Ríziani,18,,39.5286111,20.35
mx,tenextepec,Tenextepec,30,,19.466667,-97.266667
Is there any way with command line to remove everything that isn't between the first and second commas? For example, I want my list to look like this:
casa de piedra
riziani
tenextepec
with Perl
perl -F/,/ -ane 'print $F[1]."\n"' file
Use cut(1):
cut -d, -f2 inputfile
With perl:
perl -pe 's/^.*?,(.*?),.*/$1/' filename
Breakdown of the above code
perl - the command to use the perl programming language.
-pe - flags.
e means "run this as perl code".
p means:
Set $_ to the first line of the file (given by filename)
Run the -e code
Print $_
Repeat from step 1 with the next line of the file
what -p actually does behind the scenes is best explained here.
s/.*?,(.*?),.*/$1/ is a regular expression:
s/pattern/replacement/ looks for pattern in $_ and replaces it with replacement
.*? basically means "anything" (it's more complicated than that but outside the scope of this answer)
, is a comma (nothing special)
() capture whatever is in them and save it in $1
.* is another (slightly different) "anything" (this time it's more like "everything")
$1 is what we captured with ()
so the whole thing basically says to search in $_ for:
anything
a comma
anything (save this bit)
another comma
everything
and replace it with the bit it saved. This effectively saves the stuff between the first and second commas, deletes everything, and then puts what it saved into $_.
filename is the name of your text file
To review, the code goes through your file line by line, applies the regular expression to extract your needed bit, and then prints it out.
If you want the result in a file, use this:
perl -pe 's/^.*?,(.*?),.*/$1/' filename > out.txt
and the result goes into a file named out.txt (that will be placed wherever your terminal is pointed to at the moment.) What this pretty much does is tell the terminal to print the command's result to a file instead of on the screen.
Also, if it isn't crucial to use the command line, you can just import into Excel (it's in CSV format) and work with it graphically.
With awk:
$ awk -F ',' '{ print $2 }' file
The command prompt complains that it is unable to recoqnize the command.So i was thinking i needed to escape something that looked like a start of a command to the echo with the ^ character.
This is the exact line:
echo Set link = Shell.CreateShortcut(DesktopPath & "\Beta.lnk")>>%temp%\CreateFirefoxBetaShortcut.vbs
I tried:
echo ^Set link = Shell.CreateShortcut(DesktopPath & "\Beta.lnk")>>%temp%\CreateFirefoxBetaShortcut.vbs
But no luck.Im puzzled by this because it correctly enters much more complex lines but for some reason it want's to treat this line as a command not a simple text.
I can post the full .vbs including the other lines if that helps somehow.
The ampersand ("&") character has a special meaning for "cmd". Therefore, it must be preceded with a caret ("^"), like this:
echo Set link = Shell.CreateShortcut(DesktopPath ^& "\Beta.lnk")>>%temp%\CreateFirefoxBetaShortcut.vbs
I have 100 files and need to append a line in the end of each single file.
Is there a way how I can do this with Notepad++?
The answer of Lickro is great and works with Notepad++.
Here is a screenshot of the settings:
I am adding a linebreak \n and then the text.
You can search for
(.*)
and replace with
"\1"
with multiline regular expression option activated. In this case (.*) matches whole text in a file and because of the brackets around you can access the match using \1 and append something after that.
suggest you use a batch file
FOR %%G IN (*) DO echo "myline" >> %%G "C:\myDir"
should append myline to all files in myDir
