Scripting
*********
Templates I use in my scripts.

Reacting to Ctrl+c (SIGINT) with trap
=====================================
.. code-block:: bash

    control_c() {
        echo  # new line for ^C character that is printed
        echo "Exiting."
        exit 1
    }
    trap control_c SIGINT

or doing something in any case:

.. code-block:: bash

    #!/bin/bash
    set -e

    finally() {
        echo finally
    }
    trap finally EXIT

    echo before error
    false  # change me to true and see what happens
    echo after error

Looping Directories Containing Whitespace
=========================================
.. code-block:: bash

    IFS=$'\n' dirs=$(ls /tmp)
    for dir in $dirs; do
        echo $dir
    done
