Today I hosted a Beer and Tech session at Entelect on Automating Database Deployments (with Flyway).
During the session, I was using the Bash terminal to edit files or run Flyway, and interacting with git quite a bit - as we all know, using git on the command line is the best way to do so ;D
After the session, a colleague asked me how I created shortcuts for certain commands, and I explained to him how Bash supports aliases and that these can be loaded by a startup file. There are various startup files, but I tend to use ~/.bash_profile and not ~/.bashrc. Here are some of the shortcuts I currently have setup:
alias cls='clear' alias l='ls -Al' alias ..='cd ..' alias gf='git fetch --prune' alias gl='git log --name-status --abbrev-commit' alias grh='git reset --hard' alias gs='git status'
And so on. If you modify the file, you have to re-load these into the current session, or restart a new terminal session. To reload the file, you can just do the following:
$ . ~/.bash_profile
Hope this helped someone :)
