Backticks Description

Backticks is a Perl module that turns backticks into full objects which you can query in interesting ways. use Backticks; my $results = `ls -a /`; # Assign a Backticks object to $results print $results->stdout; # Get the command's STDOUT print $results->stderr; # Get the command's STDERR print $results->success; # Will be true when the command exited clean print $results; # Get the command's STDOUT... the object # stringifies to the command's output so you # can use it most places you use normal # backticksYou can have failed commands automatically die your perl script $Backticks::autodie = 1; `perl -e 'print STDERR "OUCH!\n"; exit 1'`; Which dies with the following message: Error executing `perl -e 'print STDERR "OUCH!\n"; exit 1'`: Failed with non-zero exit code 1 Error output: OUCH!You can automatically chomp output: $Backticks::chomped = 1; my $chomped = `perl -e 'print "Hello!\n"'`;You can even access parameters instantly in object mode by calling methods immediately after the backticks! say `echo foo`->stdout; # Shows 'foo' say `perl -e 'print STDERR "Hello world!"'`->stderr; # Shows 'Hello world' say `perl -e 'exit 1'`->exitcode; # Shows '1'You can also use the classical perl object-oriented interface instead of using the backticks to create objects, the following command is the same as the first one above: my $results = Backticks->run("ls -la /");Alternately, you can create a command and run it later: my $command = Backticks->new("ls -la /"); # ... do some stuff $command->run();Creating commands as an object affords you the opportunity to override Backticks package settings, by passing them as hash-style params: $Backticks::chomped = 0; my $chomped_out = Backticks->run( 'echo "Hello there!"', 'chomped' => 1, );Product's homepage
