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

   - Type: git rebase <nowiki>--</nowiki>continue
+You can also use the interactive rebase mode to look at a series of commits:
+  - Open the git branch
+  - Type: ''git rebase -i origin/main''
+  - (Optional but recommended) Save this pick list to a separate file, for recovery later if things go wrong
+  - Choose what to do with each line using the commands listed in the comment block (pick, edit, drop, fixup, squash)
+  - Save and close the "to do" file
+  - Follow the prompts to complete each step you specified
+If you need to start over, just rebase again and paste in your original pick list.

+===== Aliases =====
-==== Common Bash Commands ====
+Shortens normal commands so you type less. You can add them one at a time from the command line:
-  * ''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 $s (tab)'' --> returns list of all variables that begin with 's'
-  * ''echo (variable name)'' --> returns value of variable
-  * ''ls'' --> list visible folders and files in the current folder
-  * ''ls -a'' --> lists all of the files and folders in the current folder, including hidden files
-  * ''ls -l'' --> lists all of the folders and files in the current folder with additional detail such as last modified timestamp
-  * ''man (name of command)'' --> opens manual for that command
-  * ''mkdir newfoldername'' --> create a new folder
-  * ''mv myfile.txt myfolder'' --> moves file to folder
-  * ''notepad++ newdocname.txt'' --> create a new file and open it in notepad++
-  * ''notepad++ docname.txt'' --> edit an existing file in notepad++
-  * ''pwd'' --> see what folder you are currently in
-  * ''rmdir (myfoldername)'' --> deletes folder
-==== Vim Text Editor ====
+<code>
+$ git config alias.co checkout
+$ git config alias.cp cherry-pick
+$ git config alias.br branch
+$ git config alias.ci commit
+$ git config alias.st status
+</code>
-The vim text editor is built into the bash console (similar to notepad in Windows).
+You can also edit ''~/.gitconfig'' to see your existing aliases.
-  * ''vim'' --> opens vim text editor in command mode
+With the above aliases, you would check out main using:
-  * ''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.
+<code>git co origin main</code>
-  * ''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'
+==== Bash Aliases ====
+Mike Rylander suggests using bash aliases so you can skip typing ''git'':
+<code>
+# git-related contents of miker's ~/.bash_aliases
+alias branch='git branch'
+alias ci='git commit'
+alias co='git checkout'
+alias dif='git diff'
+alias fetch='git fetch'
+alias lg='git log --pretty=oneline'
+alias pick='git cherry-pick'
+alias pull='git pull'
+alias push='git push'
+alias stash='git stash'
+alias status='git status'
+alias wt='git worktree'
+</code>
+With these bash aliases in place, you would check out main using:
+<code>co origin main</code>
