我如何列出 shell 脚本中的所有分支列表

Question

I am coding a script that makes a comparisson between two repositories from two different cotroler systems (svn and git) for a work im doing. In svn i just took the link of the repository that is the same as i would need to checkout (pull) the branch or even the trunk (master) of it. But in git things look different and i only have a ssh link to do it, and for what i've seen so far nothing is really helping, i even tried to make a variable that was supose to go to where the ".git" archive is setup in my machine to do the git branch -a from there, cause i seen it works when i'm inside the directory using the "WSL".

in svn i did it like this

svn_trunk="https checkout link"
BRANCHES="branches"
TAGS="tags"
TRUNK="trunk"

# Branchs Configuration
SVN_BRANCHES=$BASE_SVN/$BRANCHES
SVN_TAGS=$BASE_SVN/$TAGS
SVN_TRUNK=$BASE_SVN/$TRUNK

echo '[RUN] svn ls ' $SVN_BRANCHES
svn ls $SVN_BRANCHES

echo '[RUN] git ls ' $GIT_LIST
git tag -n $GIT_LIST

the out puts asks for my credentials and then it shows all the branches from it, but i dont know how to make something similar in git way.

I tried doing somethin similar like:

GIT_BRANCHES=$GIT_URL/$BRANCHES
GIT_TAGS=$GIT_URL/$TAGS
GIT_TRUNK=$GIT_URL/$MASTER

echo '[RUN] git ls ' $GIT_BRANCHES
git branch -a $GIT_BRANCHES

echo '[RUN] git ls ' $GIT_TAGS
git tag -n $GIT_TAGS

and i was expecting that the exit listed all branches and tags out of the repository, what it isnt doing.

If you run the git commands in a repository, then git branch -a will output all the branches. For example, check the output of these commands:

git branch -a > mybranches.txt
cat mybranches.txt 

Note that you don't need to specify anything after the git branch -a command if the current directory is a git repository.

But if your current directory (pwd) is not your git repository, then you may run the following command (note the -C option and a path):

git -C "PATH/TO/GIT-REPOSITORY" branch -a

The syntax is awkward. You have to add -C PATH before the actual branch -a command.
