BEGIN not safe after errors--compilation aborted at -e line 1.


$\ is a special variable in perl that represents output record separator.

Code:
echo -e "hello\nHi" |perl -nle "BEGIN{$\='#'} print  "

1. make sure you give a space between the print and double quote which you havent done in your statement

2. try the perl comamnd in double quotes instead of single quote

Thanks

"ModPerl::PerlRunPrefork" should be used by those who run only under prefork MPM. Special Blocks "BEGIN" Blocks When running under the "ModPerl::PerlRun" handler "BEGIN" blocks behave as follows: o "BEGIN" blocks defined in scripts running under the "ModPerl::PerlRun" handler are executed on each and every request. o "BEGIN" blocks defined in modules loaded from scripts running under "ModPerl::PerlRun" (and which weren't already loaded prior to the request) are executed on each and every request only if those modules declare no package. If a package is declared "BEGIN" blocks will be run only the first time each module is loaded, since those modules don't get reloaded on subsequent requests. See also "BEGIN" blocks in mod_perl handlers. "CHECK" and "INIT" Blocks Same as normal mod_perl handlers. "END" Blocks Same as "ModPerl::Registry".
