Problem: I'm tired of typing long commands in the Linux command prompt whenever I want something done. Not only that, typing these commands is prone to typo errors.
Solution: Add a command alias to our user profile.
Here's how:
1. Edit your Linux OS user profile (or .bash_profile) and add a command alias
dbaworks@dbasrv1:~$ vi .profile
-- add the command alias
# set PATH so it includes user's private bin directories
PATH="$HOME/bin:$HOME/.local/bin:$PATH"
alias check_mongo='ps -ef | grep mongo'
2. Reload your OS user profile
dbaworks@dbasrv1:~$ . .profile
3. You can now run the command alias and get the desired result:
dbaworks@dbasrv1:~$ check_mongo
--- output
dbaworks@dbasrv1:~$ check_mongo
