First, your regext could be
$var =~ s/[\s\[\]]/\\$1/g;
Next, you should use two arguments style "system" calls:
system("/usr/local/bin/programm", args);
Third, you have to analyze a return code of a "system" command:
my $status = system(...);
print "Error [errno = $status]\n" if($status);

Oh?
I love Perl, but
perl -mstrict -we 'for(`ls`) { chomp;print `grep foo $_`; }'
By which you're basically saying the following non-Perl statement::
Right we already covered that a day or so ago, the shell is not the way
to go:
perl -mstrict -MFile::Slurp -we 'for(read_dir(".")) { print "Process
$_ here\n"; }

Something like this should work:
#!/usr/bin/perl
use warning
perl -mstrict -we 'for(`ls`) { chomp;print `grep foo $_`; }'
Yikes, please don't shell out for this, and please don't suggest newbies
should shell out for these calls. If you are going to write shell, why
not just write shell. Your "script" is completely insufficient in terms
of error handling, se
ame (@names) {
# do stuff here
}
I hope this helps
