Hello,

Here are the 2 solutions.


1st way:
Code:
awk -F"=" '{print $2}' file_name
171345
174144

2nd way:
Code:
sed 's/[a-z]//g;s/[[:punct:]]//g' file_name
171345
174144


Adding one more way to same:
3rd way:
Code:
awk -F"=" '{if($NF ~ /[0-9]/) print $NF}' file_name
171345
174144

Thanks,
R. Singh

Hello,

One more approach.


Code:
awk '{gsub(/[a-z]/,X) gsub(/[[:punct:]]/,Y);print}' file_name
171345

EDITED:

I forgot to post one more easiest solution yesterday here is that
Code:
$ cat <<test | tr -cd '[0-9]\n'
cn=171345
cn=174144
test

171345
174144

for file use like this
Code:
$ tr -cd '[0-9]\n' <file
