Handy Runner - Request For Comments


G'day all,

I wrote this script, called hr for now.

The idea behind this script is to add infinite preprocessing abilities to programs which have none. For example, I might have a script for parsing some source file into html code, and I want to view that in mozilla. Rather than
Code:
$ script_to_parse_into_html < source_file > /tmp/temp.html; mozilla /tmp/temp.html
I can use hr!
Code:
$ mozilla `hr 'script_to_parse_into_html < source_file'`
This might seem stupid, but for me, it means less typing each time. Plus, I don't have to be creative thinking of a temporary file that doesn't already exist each time.

This is a Request For Comments. Do you think this concept is stupid? Do you like it? How could the perl script be improved?

http://soundless-screams.net/pcwd/misc/hr
Code:
#!/usr/bin/perl -w

# This script passes its arguments to a shell, saving
# the output to a temporary file. This script then 
# prints the name of that temporary file to stdout.

# Make temp directory if not already there.
my $tmpdir = '/tmp/hr';
if (!(-d $tmpdir)) {
        mkdir $tmpdir;
}

my $outfile = `mktemp $tmpdir/.XXXXXX`;

my $ret;
if (!($ret = system(join(' ', @ARGV, " > $outfile")))) {
        print $outfile;
} else {
        print STDERR "hr: Error running given command! $ret";
        exit 1;
}
exit 0;
