Perl array extension in command line arguments

I want to call a shell command from a Perl script. Command arguments are present in the Perl array.

What is the easiest way to do this?

You probably need to call system, and most effectively pass the parameters in a list, which avoids using the shell to parse the command line. Call type

my $status = system 'command', @arguments;

should do what you need.

Typically, two forms are usually used to run programs:

  • takes a path and argument list
  • accepts a shell command.

The first is safer and requires less resources.

system($prog, @args);             # @args > 0
system({ $prog } $prog, @args);   # @args >= 0

, String:: ShellQuote ( unix) Win32:: ShellQuote ( Win32), .

use String::ShellQuote qw( shell_quote );
my $shell_cmd = shell_quote($prog, @args);
system($shell_cmd);
