Alias name for command can be set up using .bashrc file
.bashrc file is located in your user directory
For example if it is user who want change it, then it would be under
/home/user/.bashrc
For root user it would be
/home/root/.bashrc
Here’s the basic format
alias aliasname='commands'
Add the following to .bashrc file
alias ll='ls -lah'
alias p='pwd'
alias g='ping google.com'
No space should be made before and after the equal-to(=)sign
save and quit.
Log out and log in back to check if the alias is working or not.
You can also do source ~/.bashrc to have an immediate effect on the alias used
# source ~/.bashrc
