• git rm badfile.txt –> delete a file (if the file is being tracked, be sure to add a commit message indicating the file has been deleted)
• git show <hash> –> display the commit text and differences of the specified commmit
• git show --stat –> see what your commit will look like before you push it
• git status –> display status of current branch
• git version –> displays the installed version of Git
• gitk –> use this after committing changes but before pushing them to see what will be pushed

If your patch is behind current main, you'll need to rebase it.

1. Open the git branch
2. Type: git rebase origin/main –> rebases the current branch to main (you can do this when you have your branch checked out and changes committed, but have not yet pushed it)
3. If there are merge conflict errors, type: git status
4. Open the file with the problem in your preferred text editor (notepad++, vim, nano, etc.)
5. Look for merge conflict markers in the file (>>>) and correct the problems
6. Type: git add (problem file name)
7. Repeat steps 4-6 for each additional problem file
8. Type: git rebase --continue

If you have multiple commits in your local branch that you'd like to combine:

1. Use 'git log' to verify that the commits you want to combine are the most recent
2. Type git rebase -i HEAD~2 (where 2 is the number of commits you wish to combine)
3. Your text editor will open and should show both of the commits, for example:
   • pick 014e59c579 LP#1839359 Select element on login not accessible
   • pick 9de92lsi9a LP#1839359 Select element on login not accessible
4. Change the word "pick" in the second line to either "fixup" or "squash" then save and close the file
   • squash –> merges commits, then allows amendment of commit message
   • fixup –> merges commits like squash does, but discards previous commit message
5. Use "git commit –amend" if you need to edit the final commit message
6. Push the changes up to your remote working directory as normal

If you've already pushed multiple commits up to your remote working git repository, you can still combine them:

1. Follow the steps above, but when pushing, use "–force"
   • git push --force working lp1839359_login_select:user/jdoe/lp1839359_login_select

• cd –> move back to the home folder
• cd foldername –> move from the current folder to a child folder
• cd .. –> move up in the folder hierarchy one level
• clear –> clears your command window giving you a fresh screen to work with (also, Ctrl-l)
• cp myfile.txt myfile.bak –> copies file with new name
• diff myfile.txt otherfile.txt –> shows differences between files
• echo $ (tab tab) –> returns list of all variables
• echo $s (tab) –> returns list of all variables that begin with 's'
• echo (variable name) –> returns value of variable
• ls –> list visible folders and files in the current folder
• ls -a –> lists all of the files and folders in the current folder, including hidden files
• ls -l –> lists all of the folders and files in the current folder with additional detail such as last modified timestamp
• man (name of command) –> opens manual for that command
• mkdir newfoldername –> create a new folder
• mv myfile.txt myfolder –> moves file to folder
• notepad++ newdocname.txt –> create a new file and open it in notepad++
• notepad++ docname.txt –> edit an existing file in notepad++
• pwd –> see what folder you are currently in
• rmdir (myfoldername) –> deletes folder

The vim text editor is built into the bash console (similar to notepad in Windows).

• vim –> opens vim text editor in command mode
• vim (filename) –> opens file in vim text editor

Vim opens in command mode, which allows a variety of functions, but does not allow direct editing.

• i –> puts you into edit mode
• esc –> puts you back into command mode from edit mode
• :q –> takes you out of vim
• :w –> saves your work
• :wq –> saves & closes
• :set number –> turns on line numbers
• ?abc –> searches for occurrences of 'abc'
