G'day Blur,
Welcome to the Monastery.
Here's a pipeline containing awk:
$ echo "a b c" | awk '{print $2}'
b
Here's a Perl script containing that pipeline. Note that only the '$' needed to be escaped (\$2):
$ cat pm_1223868_heredoc_awk.pl
#!/usr/bin/env perl
use strict;
use warnings;
print <<`EOS`;
echo "a b c" | awk '{print \$2}'
EOS
It produces the same output:
$ pm_1223868_heredoc_awk.pl
b
Look at perlop - Quote-Like Operators - <<EOF
and scroll down to the Backticks entry for more about this type of heredoc in Perl.
[I see others have already mentioned the lack of information and, as this is your first post,
I won't go on about it; however, you will need to show us an example with the problem symbols
for us to help you further.]
