Unix Tip #4413- April 11, 2025
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/)}
