 - `sleep 3 & echo hey`: Executes a command in the background (the shell will not wait for the command to finish) and it will show you the job id of the background process (ex: `[1] 1234`).
 - `pwd`: Running this command will display the job id of the background process terminated (ex: `[1] done sleep 3`).

+### Alias
+
+Livl-shell provide a basic alias support. Alias can be defined only by editing the `alias.txt` file. The syntax is the following:
+
+```
+alias_name="command"
+```
+
+For example, if you want to create an alias for the `ls -l` command, you can add the following line to the `alias.txt` file:
+
+```
+ll="ls -l"
+```
+
+Then, you can run the `ll` command to execute the `ls -l` command.
+
+> Note that you can't use alias inside alias, and your input need to be exactly the alias name. You can't add arguments to an alias when using the shell.
