I thought about an alias but wanted to include some error handling and make it extensible. The nice thing about UNIX if that there is no right way of doing something so if you prefer an alias then great.

One thing I thought about was adding project specific folders. This works for both the alias and the script with &&:

ee2_permissions.sh && chmod 777 images/somefolder

eepermissions && chmod 777 images/somefolder

Eventually I'd like to be able to pass the script arguments so I'd get error handling if anything went wrong.

Accept your point it may be overkill for something so simple!
