Q. How do I clear all UNIX bash shell aliases get cleared in one command. I’ve 20 aliases sometime I just need to delete them in a current session. How do I get rid of all of them?

A. You need to use unalias command/

unalias command syntax

unalias name

To remove alias called foo, enter
$ unalias foo

alias command with no arguments or with the -p option prints the list of aliases:
$ alias
Output:

alias ll='ls -lh'
alias ls='ls --color=auto'
alias vi='vim '
alias c='clear'
alias d="/usr/local/bin/chkdomain $@"

Clear all Linux / UNIX bash shell aliases

It will remove NAMEs from the list of defined aliases. If the -a option is given, then remove all alias definitions.
$ unalias -a
