[SOLVED] How To Get RetroPie Commit Date

obsidianspider

How can I get the "Last Commit" value on my system like on the RetroPie-Setup screen?

I found the RetroPie version number in opt/retropie/VERSION but I'm trying to reverse engineer the RetroPie-Setup script to figure out how it's getting commit date and I'm obviously missing something.

I can see where the setup screen is outputting the commit variable

and I can see where the commit variable is being defined

but when I try to get the date using a simple bash script I'm getting something different than what shows up on my setup screen.

commit=$(git log -1 --pretty=format:"%cr (%h)")
echo "Last Commit: $commit"

Last Commit: 4 months ago (d7f5016)

I'm assuming it's because I need to tell the git command to pull from a different file/directory? I don't know enough about git or RetroPie to know where that should be.

Did you try to execute?:

git log -1 --pretty=format:"%cr (%h)"

;-)

Yes ;-)

$ git log -1 --pretty=format:"%cr (%h)"

It seems to be pulling a date from something different than what the RetroPie setup screen is using.

I looked here: https://git-scm.com/docs/pretty-formats
And I think you can get what you want with this command:

git log -1 --pretty=format:"%cD"

Description of some formats that might interest you:

'%cd': committer date (format respects --date= option)

'%cD': committer date, RFC2822 style

'%cr': committer date, relative

'%ct': committer date, UNIX timestamp

'%ci': committer date, ISO 8601-like format

'%cI': committer date, strict ISO 8601 format

Hope it helps.

@meleu I think the problem is that I need to know what to run the git command against.

It does it on the current git repository you are in - so what is your current directory ?

I got it!

I had to use the --git-dir parameter to tell git where to point and it looks like /home/pi/RetroPie-Setup/.git is the right location (it matches what's in the RetroPie-Setup screen)

commit=$(git --git-dir /home/pi/RetroPie-Setup/.git log -1 --pretty=format:"%cr (%h)")
echo "Last Commit: $commit"

$ ./version.sh

@BuZz git is something I know very little about, but I think I figured out how to get the versioning. Thanks :)
