Re^4: Capture external program return value

I think that could be simplified to

use IPC::System::Simple qw( capture );
my $result = capture('blastall -i foo -o bar -p blastx -d baz');

Indeed. And since IPC::System::Simple gives access to the list form for `exec`, might as well use it to save us from creating shell literals from the args. `use IPC::System::Simple qw( capture ); my $result = capture( blastall => ( -p => 'blastx', -d => $baz, -i => $foo, -o => $bar, ) );` [download] But looking at what those args are, it seems to me that it makes no sense to use backticks, `capture` or `capturex` with `-o`. `system` (or IPC::System::Simple's version) would be more appropriate.

IPC::System::Simple

exec

use IPC::System::Simple qw( capture );
my $result = capture(
   blastall => (
      -p => 'blastx',
      -d => $baz,
      -i => $foo,
      -o => $bar,
   )
);
