Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell.
It has been distributed widely as the default login shell for most Linux distributions and Apple’s macOS.
The example which is given by Mr Paul Cobbaut does not work with my terminal.
[paul@RHEL4a ~]$ echo echo Hello World > hello_world
[paul@RHEL4a ~]$ chmod +x hello_world
[paul@RHEL4a ~]$ ./hello_world
