I was investigating submodules in the pro git book <https://git-scm.com/book/en> and it documents in the tips section <https://git-scm.com/book/en/v2/Git-Tools-Submodules#Submodule-Tips> some suggested aliases. In particular (Note: I'm ignoring the '&&am;' bug and changed it to '&&'):
git config alias.sdiff '!'"git diff && git submodule foreach 'git diff'" My question is, the alias.sdiff is using the && to test for 'true | false' but I couldn't find in the 'git diff <https://git-scm.com/docs/git-diff>' documentation what the return value is. I also looked at 'git log <https://git-scm.com/docs/git-log>' or 'git' <https://git-scm.com/docs/git> suite and couldn't find the return value documented there either. A little experimentation indicates for git diff the return value is 0 (i.e. a bash true) whether there are differences or not and looks to return a non 0 value (i.e. a bash false) only when there is a 'fatal' error. Thus, the alias.sdiff makes sense, but is there documentation on the return values? -- Wink -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
