Unix Tip #4413- April 11, 2023


SEARCH : Home : Help : Today's Tip

DISPLAY ENTIRE BLOCKS


To display entire blocks of text
which contain a certain pattern,
this one-liner can be used:

cat file | perl -e "$/=''; while (<>) {print if /pattern/)}"

Of course, this can be put in a
perl-script pgrep:

#!/bin/perl
$/='';
while (<>)
{print if /pattern/)}
