git commit message as variable in linux [duplicate]

Question

This question already has an answer here:

How can I add a custom commit message to this git alias? (1 answer)

Closed 4 months ago.

I am trying in my linux (Xubuntu) console to make the git commit message in my chain of commands a variable so I can more easily execute my chain of commands.

Instead of this where I habe to edit inside the command:

b cucumber && git add . && git commit -m "my commit message" && git push && b cap staging deploy && b cap production deploy

I would like to use a variable. Something like:

1. $MSG="my new workflow"
2. b cucumber && git add . && git commit -m $MSG && git push && b cap staging deploy && b cap production deploy

Since I am a super bad at this things I would like to check back with someone who knows. Is the syntactically correct way of doing this?

Answer 1

The typical way of solving this is to declare an ad-hoc bash function in an alias where you can use numbered parameters (1,ドル 2,ドル ...), like:

git config --global alias.somename '!f() { b cucumber && git add . && git commit -m "1ドル" && git push && b cap staging deploy && b cap production deploy; }; f'
# then you can do
git somename "your message here will replace the 1ドル"

• Julian: your answer looks good @Romain Valeri. Could you elaborate more on the syntax please a little? Specifically: For what is the f needed? So I could do: git config --global alias.deploy '!f() { b cucumber && git add . && git commit -m "1ドル" && git push && b cap staging deploy && b cap production deploy }; f' Then I can do git deploy "my awesome commit" is that right? That would be awesome!
• Romain Valeri: The f stands for the ad-hoc function name, it is declared with f() { body } and it is called at the end with the simple f. And yes your renamed version looks fine :-)
• Julian: I did: git config --global alias.deploy '!f() { b cucumber && git add . && git commit -m "1ドル" && git push && b cap staging deploy && b cap production deploy }; f' and git deploy "test 2" results in => f() { b cucumber && git add . && git commit -m "1ドル" && git push && b cap staging deploy && b cap production deploy }; f: 1: Syntax error: end of file unexpected (expecting "}") What is wrong?
• Romain Valeri: @Julian Hmm...that's odd. I didn't ask before but: where are you executing the commands? I assumed bash but is it Windows cmd?
• Romain Valeri: Oh! No I see it now, we need a final ; missing after the last command inside the ad-hoc bash function, my bad! Edited my answer. Sorry for this.
• Julian: it seems to work. At least the cucumber test are running :-) Thanks a ton for support!
• Julian: no. Linux console
