I'd like to send a system command to obtain the commit of a git tag, I'm trying to do this using the git rev-parse functionality:
cmd = 'git rev-parse v1.3^{}'
[resp,cmdOut] = system(cmd)
Gives me the response:
resp =
128
cmdOut =
'v1.3{}
fatal: ambiguous argument 'v1.3{}': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
'
The ^ character does not arrive in the shell. I tested this by:
cmd = 'echo git rev-parse v1.3^{}'
[resp,cmdOut] = system(cmd)
which gives me
resp =
0
cmdOut =
'git rev-parse v1.3{}
'
I'm on a windows computer. I tried the same yesterday in octave online (https://octave-online.net/) which does give me the expected respone. I do think that octave online runs linux though.

That works on my system (W8+R2020a), so feel free to move that to the answer section.

Hmmm, maybe
cmd = 'echo git rev-parse v1.3^^{}'
(I am not using Windows so I cannot easily test myself.)

If you don't find a real solution: you can write the command to a bat file and run that instead. You can use the > symbol to redirect the output to a plain text file, which you can then read back.
You might want to use tempname to generate file names in the temp folder of the system running your function. That way you have the best chance of write access.

Maybe you need to escape it in some way. I'm on mobile so I can't test it for you.
