Perl escaping argument for bash execution

Question

Answer 1

Use quotemeta:

my $arg1 = quotemeta('string to be escaped');
`echo $arg1`

Or \Q\E (which is exactly what quotemeta is);

my $arg1 = 'string to be escaped';
`echo \Q$arg1\E`

And also please note that using echo is a bad way to print arbitrary strings.

And do NOT place any quotes around parameters if you're using quotemeta.
