How to create custom commands in Unix/Linux?
Create a bash script in your /usr/bin folder, it should look something like this
#!/bin/bash
Whatever combination of commands you want to run when you type this thing.
Its really that easy.
Just name the bash script what you want to type in to the terminal, and make it excecutable: chmod +x filename
and you're good to go!
- Create a directory say "bin" under your home directory.
Update your path variable to include this bin directory. Put this in
.profile
or.bash_profle
file to make it permanent.export PATH=$PATH":$HOME/bin"
Create a script say, "hello" and keep it in your bin directory. Give execute permission to the hello script by
$ chmod +x hello
.#!/bin/bash echo My first program
Reload
.profile
or.bash_profle
:$ . ~/.bash_profile
From any directory, you simply type:
$ hello My first program
Easy, create an alias.
Say you want to write a command to cd into your download directory. And you want to call it cdd.
alias cdd='cd ~/Downloads'
You can create any command you want.
