We can add as many aliases as we want in a bash profile. Here are two more examples:
alias hy="history"
hy
is set as an alias for the history
command in the bash profile. The alias is then made available in the current session through source
. By typing hy
, the command line outputs a history of commands that were entered in the current session.
alias ll="ls -la"
Likewise, the code above sets ll
as an alias for ls -la
. Once the alias is made available in the current session through source
, the command ll
now executes ls -la
and outputs all contents and directories in long format, including all hidden files.
Let’s add these to our bash profile!
Instructions
Open ~/.bash_profile in nano.
In the bash profile, beneath the previous alias, add the alias hy
for the command history
.
On the next line, add the alias ll
for the command ls -la
.
Save the file, and close out of nano
.
Once you’ve exited nano and are back in the terminal, press the Enter key onto a new line.
In the command line, use source
to activate the changes to the bash profile for the current session.
Try out the alias hy
.
Try out the alias ll
.
You should see the same result as ls -la
