Useful filesystem commands

Note Always try to use tab whenever possible, it saves on spelling errors and helps you move faster

pwd: Print Working Directory tells you where in the filesystem you are
cd: change directory
- cd ../ will put you into the parent directory (up a level) from where you are
- cd ~ will put you into your home directory
- cd /some/file/path/to/some/directory will put you in to the folder path you described
ls: list directory contents
- ls -a lists all contents including hidden files
- ls -l lists all files and shows information about them such as modified date and size
- ls / will show "normal" files in your root directory
- combining all of these you could show all files in the root, and the data about them using ls -la /
cp: copy
- cp -r /source/directory/name/ /destination/directory/ will copy the content of source to destination
- cp file_1 new_file will make a copy of file_1 named new_file
mv: moves and renames files and directories
- mv directory1/ /some/other/directory/location/ will move the directory into the destination provided
- mv file_name newFileName will rename file_name to newFileName
find: find files and directories
- find /tmp -type f -empty -delete will find all empty files in the /tmp dir and delete them

Note: You have to be in a git repository (directory) to use git commands

git status: shows you the current status including branch and file status
git checkout branch-name: will check you out to a branch called branch-name
git checkout -b branch-name: will create and check you out to a branch called branch-name
git add filename: will stage the changes in filename to be committed
git add .: will stage the changes in all files to be committed
git commit -am "this is where you message goes": will stage and commit all files that are currently tracked by git
git branch --merged main | grep -v 'main$' | xargs git branch -d this allows you to safely delete all branches that have been merged into master on github

git clone url cd <repository name>

git checkout -b <name-of-branch>
create and update some files
git status
git add <filename(s)>
git commit -m "the message that identifies what changes were made"
git push -u origin <name-of-branch>
at this point you can continue editing code and making commits and pushing those commits by repeating steps 2-5 and running git push without the -u argument
create a pull request
add a reviewer to the pull request
assign yourself to the pull request
once approved merge the request into main/master
git checkout main/master
git pull -p
