Hi, I'm thinking how to find the oldest tag containing a specified commit. Eg. $ cd /usr/src/linux-linus/Documentation $ for i in *.txt; do for> echo $i for> hash=`git log -1 --format=format:%H -- $i` for> git tag --contains $hash -l 'v2.6.[0-9][0-9]'|head -1 for> done DMA-API.txt v2.6.31 DMA-ISA-LPC.txt v2.6.20 DMA-attributes.txt v2.6.27 ...

Here I wonder whether "head -1" is generally correct or not when I want the oldest tag. Moreover, as "git tag --contains ..." takes considerable time, I will be happy if I can set the maximum number in searching tags containing a commit. Or are there already some (better) ways to achieve this?

Any advice is welcome.

Thanks, Kai
