If you find yourself repeatedly running a wordy command, having to look up how to run a command, or forgetting a username and password combination, I suggest looking into creating a bash alias.
To create a bash alias, do the following:
1. Start up terminal
2. Type cd ~ to go to your home folder
3. Type touch .bash_profile to create the new file
4. Type vim .bash_profile or open this file in your favorite editor.
5. Add your alias by adding a line to this file in the format alias <alias name>='<command>’ . For example alias gw=’./gradlew’. This will create an alias named gw , which when typed will run the command ./gradlew from wherever gw is typed.
6. Type . .bash_profile to reload your bash profile which loads any newly added aliases.
At this point you can type your alias instead of the wordy command you had been previously typing.
