(q{'} x (length($1) / 4)) . q{"'}|ge; $_ = "'$_'"; s/^''//; s/''$//; } } continue { $ret .= "$_ "; } chop $ret; return \@err, $ret; } =item B<shell_quote> [I<string>]... B<shell_quote> quotes strings so they can be passed through the shell. Each I<string> is quoted so that the shell will pass it along as a single argument and without further interpretation. If no I<string>s are given an empty string is returned. If any I<string> can't be safely quoted B<shell_quote> will B<croak>. =cut sub shell_quote { my ($rerr, $s) = _shell_quote_backend @_; if (@$rerr) { my %seen; @$rerr = grep { !$seen{$_}++ } @$rerr; my $s = join '', map { "shell_quote(): $_\n" } @$rerr; chomp $s; croak $s; } return $s; } =item B<shell_quote_best_effort> [I<string>]... This is like B<shell_quote>, excpet if the string can't be safely quoted it does the best it can and returns the result, instead of dying. =cut sub shell_quote_best_effort { my ($rerr, $s) = _shell_quote_backend @_; return $s; } =item B<shell_comment_quote> [I<string>] B<shell_comment_quote> quotes the I<string> so that it can safely be included in a shell-style comment (the current algorithm is that a sharp character is placed after any newlines in the string). This routine might be changed to accept multiple I<string> arguments in the future. I haven't done this yet because I'm not sure if the I<string>s should be joined with blanks ($") or nothing ($,). Cast your vote today! Be sure to justify your answer. =cut sub shell_comment_quote { return '' unless @_; unless (@_ == 1) { croak "Too many arguments to shell_comment_quote " . "(got " . @_ . " expected 1)"; } local $_ = shift; s/\n/\n#/g; return $_; } 1; __END__ =back =head1 EXAMPLES $cmd = 'fuser 2>/dev/null ' . shell_quote @files; @pids = split ' ', `$cmd`; print CFG "# Configured by: ", shell_comment_quote($ENV{LOGNAME}), "\n"; =head1 BUGS Only Bourne shell quoting is supported. I'd like to add other shells (particularly cmd.exe), but I'm not familiar with them. It would be a big help if somebody supplied the details. =head1 AUTHOR Roderick Schertler <F<roderick@argon.org>> =head1 SEE ALSO perl(1). =cut
