Learn some basic Linux! 101
It helps to learn a little bit of Linux / Unix when working on websites. Here's a quick set of commands you might find helpful:
cd - change the current working directory. When changing directories, you can press tab to autocomplete or tab twice to give a list of files/directories. Tab completion works for other linux commands as well.
move up one directory
change directory to client
move to your personal home directory
ls - list files in the current working directory
grep - useful for searching the content of files.
grep -R “search string here” ./
This will recursively search each directory from the current path.
