I need to used sed for following requirment using sed
I have one string as $str and I need to replace blow line in a file
abh{1..$abh} cdf_$ghu,xyz * abh{}.$xy
New modified line should be as below
abh{1..$abh} cdf_$ghu,$str * abh{}.$xy
Note "xyz" can be any arbitrary value. Could you please tell me how to do using sed in one liner.
sed 's/\(^\s*abh{1..$abh}\s*\)\(.*xyz\)/\1/' file.txt
but still does not work. Any help would be appreciated.
Try this:
$ sed 's|\(\S\+\s\+[^,]\+,\)\S\+\(\s\+.*\)|\1$str\2|' file.txt
abh{1..$abh} cdf_$ghu,$str * abh{}.$xy
Or even more simple:
$ sed 's|,\S\+|,$str|' example.txt
echo 'abh{1..$abh} cdf_$ghu,xyz * abh{}.$xy' | sed 's/\(.*\$ghu,\)\(.*\)\( .*\)/\1\$str\3/g'

I know how to replace sting via sed:
sed -i "s|.*#app-${BRANCH}-log.*| Path ${LOG_PATH} #app-${BRANCH}-log|" /etc/td-agent-bit/td-agent-bit.conf
and this is work for file like
[INPUT]
Name tail
Path /var/lib/docker/containers/f774c1a3689dfffb2528833ac2ded629c3b1873fd3af96fe0cf1f041f22f88d8/f774c1a3689dfffb2528833ac2ded629c3b1873fd3af96fe0cf1f041f22f88d8-json.log #app-develop-log
Tag app.develop
Interval_Sec 1
but how to replace next line? for example:
#This line just for triggering sed
And this one must be replaced
Any idea? Sorry for my horrible English.
With GNU sed:
sed '/^#This line just for triggering sed$/{n;s/.*/foo/}' file
Output:
#This line just for triggering sed
foo
See: man sed
I a file containing the genome ids following NZ_FLAT01000030.1_173 I need to manipulate those ids like this one: NZ_FLAT01000030.1
I tried some but didn't give me the exact thing.
sed 's/_/\t/' output : NZ FLAT01000030.1_173
sed -r 's/_//' output: NZFLAT01000030.1_173
sed -r 's/_//g' output: NZFLAT01000030.1173
How can I do that by using sed command?
Are you trying to remove the undesrscore and the digits following it?
echo 'NZ_FLAT01000030.1_173' | sed -E 's/_[0-9]+//g'
NZ_FLAT01000030.1
$ echo 'NZ_FLAT01000030.1_173' | sed 's/_[^_]*$//'
NZ_FLAT01000030.1
27211;18:05:03479;20161025;0;0;0;0;10991;0;10991;000;0;0;000;1000000;0;0;000;0;0;0;82
Second string after ; is time. gg:mm:sssss:. I just want to be gg:mm:ss:
Like so:
27211;18:05:03;20161025;0;0;0;0;10991;0;10991;000;0;0;000;1000000;0;0;000;0;0;0;82
I tried with cut but it deletes everything after n'th occurance of character, and for now I am stuck, please help.
give this one liner a try:
awk -F';' -v OFS=";" 'sub(/...$/,"",$2)+1' file
It removes the last 3 chars from column 2.
update with sed one liner
If you are a fan of sed:
sed -r 's/(;[^;]*)...;/\1;/' file
With sed:
sed -r 's/^([^;]+;[^;]+)...;/\1;/' file
(Or)
sed -r 's/^([^;]+;[0-9]{2}:[0-9]{2}:[0-9]{2})...;/\1;/' file
It also can be something like sed 's/(.*)([0-9]{2}\:){2}([0-9]{3})[0-9]*\;(.*)/\1\2\3\4/g'
It is not very clean, but at least is more clear for me.

I'd use perl for this:
perl -pe 's/(?<=:\d\d)\d+(?=;)//' file
That removes any digits between "colon-digit-digit" and the semicolon (first match only, not globally in the line).
If you want to edit the file in-place: perl -i -pe ...
With sed:
sed -E 's/(:[0-9]{2})[0-9]{3}/\1/' file
or perl:
perl -pe's/:\d\d\B\K...//' file
Due to the know prob of mocha-lcov-mocha breaking file paths, I need to fix the current output paths that looks like this:
SF:Vis/test-Guid.coffee
SF:Vis/Guid.coffee
SF:Vis/test-Vis-Edge.coffee
SF:Vis/Vis-Edge.coffee
into
SF:test/Vis/test-Guid.coffee
SF:src/Vis/Guid.coffee
SF:test/Vis/test-Vis-Edge.coffee
SF:src/Vis/Vis-Edge.coffee
I'm not very good with sed, but I got it to work using:
mocha -R mocha-lcov-reporter _coverage/test --recursive | sed 's,SF:,SF:src/,' | sed s',SF.*test.*,SF:test//&,' | sed s',/SF:,,' | sed s',test/src,test,' | ./node_modules/coveralls/bin/coveralls.js
which is basically doing 4 sed commands in sequence
sed 's,SF:,SF:src/,'
sed s',SF.*test.*,SF:test//&,'
sed s',/SF:,,'
sed s',test/src,test,'
my question is if there is a way to do with this one sed command, or use another osx/linux command line tool
Initially put "src/" after every ":" and then if "test" is found on the line replace "src" with "test":
$ sed 's,:,:src/,;/test/s,src,test,' file
SF:test/Vis/test-Guid.coffee
SF:src/Vis/Guid.coffee
SF:test/Vis/test-Vis-Edge.coffee
SF:src/Vis/Vis-Edge.coffee
You could put all the sed commands in a file, one line per command, and just use "sed -e script". But if you just want it on a single command-line, separate with semicolons. This works for me:
sed 's,SF:,SF:src/,;s,SF.*test.*,SF:test//&,;s,SF:,,;s,test/src/,test,'
sed command
sed '\#test#!{s#SF:Vis/#SF:src/Vis/#g};\#SF:Vis/test#{s#SF:Vis/test#SF:test/Vis/test#g};' my_file
Here is an awk version:
awk -F: '/SF/ {$0=$1FS (/test/?"test/":"src/")$2}1' file
SF:test/Vis/test-Guid.coffee
SF:src/Vis/Guid.coffee
SF:test/Vis/test-Vis-Edge.coffee
SF:src/Vis/Vis-Edge.coffee
How it works:
awk -F: ' # Set field separator to ":"
/SF/{ # Does line start with "SF"?
$0=$1FS (/test/?"test/":"src/")$2 # Recreat String by adding "test" if line contains "test", else "src"
}
1 # Print all lines
' file # read the file
I have a file data.txt with the following strings:
text-common-1.1.1-SNAPSHOT.jar
text-special-common-2.1.2-SNAPSHOT.jar
some-text-variant-1.1.1-SNAPSHOT.jar
text-another-variant-text-3.3.3-SNAPSHOT.jar
I want to change all of the text-something-digits-something.jar to text-something-5.0.jar.
Here is my script with sed (GNU sed version 4.2.1
), but it doesn't work, I don't know why:
#!/bin/bash
for t in ./data.txt
do
sed -i "s/\(text-[a-z]*-(\d|\.)*\).*\(.jar\)/\15.0\2/" ${t}
done
What is wrong with my sed usage?
How about this awk
awk '/^text/ {sub(/[0-9].*\./,"5.0.")}1'
text-common-5.0.jar
text-special-common-5.0.jar
some-text-variant-1.1.1-SNAPSHOT.jar
text-another-variant-text-5.0.jar
text-something-digits-something.jar to text-something-5.0.jar
equal change digits-someting to 5.0
It also takes care of changing line only starting with text
I think a simpler approach might be enough: sed -r -e 's/(text-(.*-)?common-)([0-9\.]+)(-.*\.jar)/\15.0\4/' < your_data.
Another way of saying the same thing with perl: perl -pe 's/(text-(?:(.*-))*common-)([\d\.]+)(-.*\.jar)/${1}1.5${4}/' < your_data.
#!/bin/bash
for t in ./data.txt
do
sed -i '/^text-/ s/[.0-9]\{1,\}-something\(\.jar\)$/5.0\2/' ${t}
# for "any" something
#sed -i '/^text-/ s/[.0-9]\{1,\}-[^?]\{1,\}\(\.jar\)$/5.0\2/' ${t}
done
select string starting with text and change digit value is present
Using sed:
sed '/^text-/ s/-[0-9.]*-/-5.0-/' file
