Git History.

Want to take a spin in the good old git time machine? Here are some useful way to do that.

git show --name-only [sha]

Show which files have changed between the referenced [sha] and the current HEAD.

git log --grep=[stuff]

Show any commits where the commit message matches the regular expression [stuff].

git log -p [filename]

Show the log (commits and changes) for a the file [filename]. You can add any log arguments to this, such as 25 for only the most recent entries in the log: git log -p -25 README.md.

git grep [stuff]

Use the power of git to search for any matches of the regular expression [stuff] in the repo.

Piping Output

• If the results are too difficult to read in your terminal, you can pipe the results to your test editor. For example, to pipe the output to Sublime from OSX's Terminal: git log -p -2 README.md | subl.
• Or you can pipe those results to a file to save them. For example, to send the results to a file in Windows' Command Line: git log -p -25 > file.txt
