I have to do next thing!
Here is for exmaple next text:
0 ONAIR: PolinaGhffith RalphGood-SOS OhginaIMix
I ned to extract just
PolinaGhffith RalphGood-SOS OhginaIMix
But the problem is that sometimes text is showed without 0 ONAIR:
I try with next code but it won't do it this job allways!
sed -e 's/_..........: //' -e 's/\t//g' -e 's/_//g'
I know that it delete all tabulators and "_" caracters, and it omits 0 ONAIR: but it won;t work every time :(
Thx!
grep
kent$ echo "0 ONAIR: PolinaGhffith RalphGood-SOS OhginaIMix"|grep -Po '(?<=: ).*$'
PolinaGhffith RalphGood-SOS OhginaIMix
awk
kent$ echo "0 ONAIR: PolinaGhffith RalphGood-SOS OhginaIMix"|awk -F': ' '{print $2}'
PolinaGhffith RalphGood-SOS OhginaIMix
sed
kent$ echo "0 ONAIR: PolinaGhffith RalphGood-SOS OhginaIMix"|sed 's/^.*: //'
PolinaGhffith RalphGood-SOS OhginaIMix

I expected sed 's/\s+$//g' to strip trailing spaces
echo "'$(echo 'Magnetic ' | sed 's/\s+$//g')'"
outputs 'Magnetic ', as does
echo "'$(echo 'Magnetic ' | sed 's/[\n\s]+$//g')'"
How do I remove the trailing space with sed?
You have to escape the plus sign + because sed uses BRE, so:
echo "'$(echo 'Magnetic ' | sed 's/\s\+$//g')'"
if there's -r or -E flag, sed uses ERE instead so you don't have to escape it:
echo "'$(echo 'Magnetic ' | sed -r 's/\s+$//g')'"
I am trying to replace all escaped characters \" in a string with "" but not if \" is preceded by a \
So that input such as:
\"\"\"\" would return """"""""
\"\\"\"\" would return ""\\"""""
\" would return ""
\"\" would return """"
\\"\" would return \\"""
\"\\" would return ""\\"
\\\\\\\" would return \\\\\\\"
So far I have
$ echo sed -e 's/\([^\]\)\\"/\1""/;s/^\\"/""/'
but in the case of
$ echo '\"\"\"\"\"' | sed -e 's/\([^\]\)\\"/\1""/;s/^\\"/""/'`
I am getting incorrect results.
Any help would be appreciated.
This might work for you (GNU sed):
sed 's/\\\\"/\n/g;s/\\"/""/g;s/\n/\\\\"/g' file
Replace all occurances of the string you want untouched by something else (\n is a good choice), replace the string you want changed globally, reinstate the first set of strings.
How about this:
#!/bin/bash
function myreplace {
echo "$1" | sed -e "s/[\\]\"/MYDUMMY/g" \
-e 's/\\MYDUMMY/\\\\"/g' \
-e 's/MYDUMMY/""/g'
}
myreplace '\"\"\"\"'
myreplace '\"\\"\"\"'
myreplace '\"'
myreplace '\"\"'
myreplace '\\"\"'
myreplace '\"\\"'
myreplace '\\\\\\\"'
Executing the script above results in:
""""""""
""\\"""""
""
""""
\\"""
""\\"
\\\\\\\"
Using a sed loop will allow not having to pick a unique replacement string for an unknown dataset.
sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
$ echo '\"\"\"\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g;t inner'
""""""""
$ echo '\"\\"\"\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
""\\"""""
$ echo '\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
""
$ echo '\"\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
""""
$ echo '\\"\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
\\"""
$ echo '\"\\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
""\\"
$ echo '\\\\\\\"' | sed -e 's/^\\"/""/;:inner; s/\([^\]\)[\]"/\1""/g; t inner'
\\\\\\\"
I have the following script for extraction of logs.

All the commands except zcat can be consolidated into a single awk or perl script: I don't have the time to help you with that right now.
I have a example cut down from a log file.
112 172.172.172.1#50912 (ssl.bing.com):
I would like some how to remove the # and numbers after and (): from the url.
Would like the result.

Here is the sed oneliner I have been working on.
cat newdns.log | sed -e 's/.*query: //' | cut -f 1 -d' ' | sort | uniq -c | sort -k2 > old.log
Thanks
Using sed, you could say:
sed 's/#[0-9]*//;s/(\(.*\)):$/\1/' filename
or, in a single substitution:
sed 's/#[0-9]* *(\(.*\)):$/ \1/' filename
Another sed:
sed -r 's/#[^ ]+|[():]//g'
$ echo '112 172.172.172.1#50912 (ssl.bing.com):' | sed -r 's/#[^ ]+|[():]//g'
112 172.172.172.1 ssl.bing.com
I am trying to execute a shell file, in which there is a line:
sed -ne ':1;/PinnInstitutionPath/{n;p;b1}' Institution | sed -e s/\ //g | sed -e s/\=//g | sed -e s/\;//g | sed -e s/\"//g | sed -e s/\Name//g
And un error message turns out : "Label too long: :1;/PinnInstitutionPath/{n;p;b1}"
I am a noob at linux, so can anyone help me to solve this problem, thank you!
Try changing
sed -ne ':1;/PinnInstitutionPath/{n;p;b1}'
to
sed -ne ':1' -e '/PinnInstitutionPath/{n;p;b1}'
Also, you don't need to call sed so many times:
sed -ne 's/[ =;"]//g; s/Name//g' -e ':1' -e '/PinnInstitutionPath/{n;p;b1}'
Concerning 'sed: Label too long' in Solaris (SunOS) - you will need to split your command into several lines, if you use labels.
In your casesed -ne ':1
/PinnInstitutionPath/{
n
p
b 1
}' Institution | sed -e s/\ //g -e s/\=//g -e s/\;//g -e s/\"//g -e s/\Name//g
