5/8     is there a perl equiv of the php "escapeshellarg()" function?
        \_ Tell us what escapeshellarg actually does (I can guess but...).
           I know perl but not php.  I'm sure I'm not the only one.
           \_ I'm trying to untaint a var that i will pass to a shell cmd.
              I think $ARGV[0] =~ s(')('\\'')g  should do it, but <shrug>.
        \_ You may want to look at quotemeta, but this sounds like an ugly
           hack.
           \_ open(FOO,"\Q$tainted\E |");
