Hi,
for my Linux-kernel build-script I am searching for a reliable check
of getting the ***latest*** version.
This could be 'v3.x.y-stable' or 'v3.x.y-rcX'.
'git tag' seems to be fast, but not reliable.
'git log --oneline' is slow, but does the job.
For getting v3.x.y-stable this seems to work...
$ git tag | grep ^'v3.[0-9]*' | grep -v '\-rc' | sort --version-sort
v3.0
v3.1
v3.2
v3.3
v3.4
v3.5
v3.6
v3.7
v3.8
v3.9
v3.10
...but not when listing v3.x.y-rcX, too:
$ git tag | grep ^'v3.[0-9]*' | sort --version-sort | grep ^'v3.10'
v3.10
v3.10-rc1
v3.10-rc2
v3.10-rc3
v3.10-rc4
v3.10-rc5
v3.10-rc6
v3.10-rc7
I know that v3.10 > v3.10-rcX, but not 'git tag' or 'sort --version-sort' :-).
This seems from my poor sed/awk/grep skills to be the most reliable method...
$ time git log --oneline v3.0-rc1.. | grep 'Linux 3.' | awk '{ print
$3 }' | grep ^'3.[0-9]*' | head -1
3.10
real 0m10.024s
user 0m5.611s
sys 0m4.857s
...but is slow (even I take v3.0-rc1 as the 1st version-tag of
Linux-v3.x series).
Any improvements?
Thanks in advance.
Regards,
