Displaying All Aliases in the Current Shell

alias -or- alias -p

The command to display all aliases defined in the current shell is:

bashCopy code
alias 

This command without any arguments will list all the aliases defined in the current shell session. An alias is a shortcut for a command or a set of commands. When an alias is defined, you can use the alias instead of typing the full command. For example, you can define an alias for the ls command to always include the -l option:

bashCopy code
alias ll='ls -l' 

Now, you can use the ll alias instead of typing ls -l every time:

diffCopy code
$ ll total 0 -rw-r--r-- 1 user user 0 Mar 13 20:49 file1 -rw-r--r-- 1 user user 0 Mar 13 20:49 file2 

Note that aliases are only defined for the current shell session. If you open a new terminal window, you will need to redefine the aliases. Also, aliases are not available in shell scripts, so you will need to use the full command in a script.
