============

git status

• shows status of all files in repo
• untracked- hasn’t been anywhere yet
• unmodified- unchanged from last commit/ from after pulling
• modified- changed, but not set to commit yet
• staged- going to commit soon

git add <filename> [<filename> <filename> ...]

• add file’s content to next commit
  • -start TRACKING that file, STAGE files, mark
    • merge-conflicted files as RESOLVED, etc
• see names of untracked files w/ git status
• ex: git add README
• -s
  • makes output shorter
  • M = modified
  • A = added
  • ?? = not tracked
  • 2 columns of symbols ^^
    • left = staging area status
    • right = working area status git commit
• commits the changes in staging area (see git status)
• w/o -m
  • opens core editor to type message describing commit
  • close core editor window to proceed
• -m
  • type commit message w/o opening core editor
• -a
  • commit everything that was changed (skip staging area)

cat .gitignore <press enter> <what to ignore> <enter> <etc>

• make those files not show up in git status
• • *.[extension] - ignore w/ that extension
  • *[part of name] - ignore w/ that in end of name
  • (note the * in front)
  • disregards lines with # (comment)
• no .a files
  • *.a
• but do track lib.a, even though you’re ignoring .a files above
  • !lib.a
• only ignore the TODO file in the current directory, not subdir/TODO
  • /TODO
• ignore all files in the build/ directory
  • build/

  • ex: lines of code that were changed
• if discluded, shows all files i think

git log

• gives list of commits w/ their message

git show <commit>

• display what changed in that commit (git log?)
• can be HEAD => the commit you're currently on

git checkout <commit> <filename>

• restore that file in working directory to that commit’s version

git help <commandName>
