Using alias commands you can easily perform your regular jobs.
1, open "~/.bashrc" in any editor.
vi ~/.bashrc
2. Add your alias commands at the end of the file.
Ex:
#Tomcat Alias
alias starttomcat='/usr/apache-tomcat-6.0.26/bin/catalina.sh jpda start'
alias stoptomcat='/usr/apache-tomcat-6.0.26/bin/catalina.sh jpda stop'
alias cleantomcat='sudo rm -rf /usr/apache-tomcat-6.0.26/work/Catalina/localhost/*'
alias ctlog='tail -f /usr/apache-tomcat-6.0.26/logs/catalina.out'
alias flushctlog='>/usr/apache-tomcat-6.0.26/logs/catalina.out'
#Apache Alias
alias startapache='sudo /etc/init.d/apache2 start'
alias startapache='sudo /etc/init.d/apache2 stop'
alias restartapache='sudo /etc/init.d/apache2 restart'
3. load the aliases again.
. ~/.bashrc
Now you can use the alias name any where in the command prompt.
