I'd been doing something a little crazy-sounding that I thought I should share (for what it is worth). My problem was that this expense Thomas mentioned was not just on first entering a repo, but on *each* command, for some of my users (long story... old hardware, wrong kind of "corporate mandated" software, Windows... please don't ask <sigh>)
Also, instead of just a symbol, I wanted a *count* of how many files are staged (git added), modified, untracked, unmerged, etc. A color-coded number for each type would be great.
But I couldn't run this extra stuff at every prompt. I wanted it to kick in only when
* I change directories, or
* I switch branches, or the branch state (according to
__git_ps1) changes, or
* when I want it to, but I won't type a command (huh?)The idea is that it should be as convenient and accessible as the current __git_ps1, but it shouldn't really happen on every prompt.
That last part is a bit of a hack, but basically, if you hit enter twice in a row quickly at the bash prompt, you get the more detailed stuff added to __git_ps1's output :-)
Sounds crazy but if you try it, you might just like it... The link to the shell script is toward the end of http://sitaramc.github.com/2-command-line-usage/souped-up-bash-prompt.html
Comments welcome but please be kind. I'm still learning git, compared to most of you lot :-)
