bash-command-printer

A minimal bash script to print each command being run in a bash script

Getting started

Getting started with the command printer is easy! Just source the command-printer file and run the activate_command_printer function. That's it!

#!/usr/bin/env bash

# To activate the command printer
. command-printer
activate_command_printer

# Your script here
echo "Hello world"

You can also choose to activate the command printer later in the script if you don't care about printing e.g. setup commands:

#!/usr/bin/env bash

# To activate the command printer
. command-printer

# Your setup code

activate_command_printer

# Your script here
echo "Hello world"
