Creating custom commands

When using CLI of linux based OS', some regular commands that we perform everyday, even multiple times everyday, becomes a burden to type again and again. Luckily we have a simple way to ease up small stuff like that.

Let's assume that we're doing some work on our web site that has database interaction, and each time we change a configuration setting we need to restart the httpd and db services.


#service httpd restart
#service postgresql-9.0 restart

Typing 6 words every time. I am too lazy for that kind of stuff. Instead I created a new alias in the .bashrc file in my home folder. if you have a look at your profiles .bashrc file, you'll most likely see other aliases already configured by default. So just add another line, and log off/on or source that file.

#cd /root
#vi .bashrc


....

alias mv='mv -i'
alias rm='rm -i'
alias mycustomcommand='service httpd restart; service postgresql-9.0 restart'

.....

#source .bashrc

This simple tweak will definitely come in handy.
