Running Linux Command Through Ruby

Rails
1

I wonder if anyone knows how to run Unix/Linux commands from Ruby?

I understand that the Perl counterpart could be sth like the
following.

  • First I create a perl file example.pl

  • Then inside the file I have the desired Linux commands.

#!/usr/local/bin/perl -w
ls -l;
curl google.com;

  • When I run the file, those Linux commands would be executed.

Just wonder how I can do this in Ruby in Linux environment. Thanks a
lot!

exactly the same: by enclosing the command in backticks (`)
you’ll get the output produced as the return value, and the exit code
is in $?
