The here operator with the sort command

Let's write a script for using the sort command along with the here document:

  1. Write the script here_02.sh as follows:
#!/bin/bash 
sort << EOF 
cherry 
mango 
apple 
banana 
EOF 
  1. Save the file, give the permission to execute, and run the script as follows:
    $ chmod u+x here_02.sh
    $ ./here_02.sh
  
  1. The output is here:
    apple
    banana
    cherry
    mango
  

In this script, the here document is enclosed between the EOF pattern. We have used the here document to supply text to the sort command.
