Common Terminal Commands

Key Commands & Navigation

Before we look at some common commands, I just want to note a few keyboard commands that are very helpful:

Up Arrow: Will show your last command
Down Arrow: Will show your next command
Tab: Will auto-complete your command
Ctrl + L: Will clear the screen

Clone the repo.
Use git rebase -i --root
vim will open. Select the commits you want to modify by changing pick to edit. If you would like to change all the commits, perform the following replace: :%s/^pick/edit/g. This command changes all instances of "pick" at the start of lines to "edit".
You will now be shown all the selected commits one by one. Each commit message will be displayed. You have two options:
- If you would like to keep the commit author details the same, do a git rebase --continue.
- If you would like to change it to a different name/email, do git commit --amend --reset-author. If --reset-author is specified, it will use the details from your git config. (If you need to specify an alternate name/email, you can do so with --author="John Doe <[email protected]>". If you would like to change the time to a previous date, you can do so with --date "2 days ago".)
Do the same for all the commits and finish the rebase.
Perform git push -f origin master to

exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

If Disk Utility is unable to repair, consider trying this:

In Disk Utility, ensure that the drive is not mounted, eject it if it is mounted.
Use diskutil list to find the right drive id.
You want the id under the IDENTIFIER column, it should look like disk1s1
Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
-d is debug so you'll see all your files output as they're processed.

	## I just ran into this after initializing a Visual Studio project _before_ adding a .gitignore file (like an idiot).
	## I felt real dumb commiting a bunch of files I didn't need to, so the commands below should do the trick. The first two commands
	## came from the second answer on this post: http://stackoverflow.com/questions/7527982/applying-gitignore-to-committed-files

	# See the unwanted files:
	git ls-files -ci --exclude-standard

	# Remove the unwanted files:
	git ls-files -ci --exclude-standard -z \| xargs -0 git rm --cached
