Re: Reading special characters from file?

Yup there are loads of ways ;-)¹ Although as it's been said there are few situations when you can implicitly use them as values.
1. quotemeta() being the most obvious.

quotemeta() did the trick. The problem was occurring because I passed the files to the shell using: `$cmd = 'someshellexe ' . $basepath . '/' . $file; $rc = qx($cmd);` [download] The `$` was being interpreted when passed to the shell. Changing this to: `$cmd = 'someshellexe ' . $basepath . '/' . $file; $escapedcmd = quotemeta($cmd); $rc = qx($escapedcmd);` [download] worked like a charm. Thanks to all for the help!	[reply] [d/l] [select]

A hint: you can do that a bit more readably by using interpolation -- note that Perl won't doubly interpolate, even though the shell might once you pass the value to it: `$cmd = "someshellexe $basepath/$file"; $cmd = quotemeta($cmd); $rc = qx($cmd); #` [download] ... unless, as I take it, $rc eq 'result code', in which case use `$rc = system($cmd)`, unless the result code is actually in the output of the command, in which case use qx.
