An environment variable with equal sign and && operator

Question

I want to create an environment variable for this command:

git --git-dir= echo test-folder/.git/ add Steps-to-follow.txt && git --git-dir= echo test-folder/.git/ commit

This is a relevant excerpt from my ~/.bash_profile:

export git11='git --git-dir='
export equal==
export git12='test-folder/.git/ add Steps-to-follow.txt && git --git-dir='
export git13='test-folder/.git/ commit'

I tried $variable-name one after the other for all those variables but I think the shell blob, on expanding, is not passing it in the way I want it to appear (due to standards compliance of some type).

1. I haven't really used export equal== but I have it there (I was trying random thing for it to work).

2. I tried piping the commands but that's stupid, that is not supposed to work.

3. I think the issue is with = sign in the environment variable (probably it is assuming the start of some other assignment). Meta character type input is not working (i.e., \= in place of =).

Some help in this will be really helpful.

I’m not familiar with git, so I don’t really understand what you are trying to do — in particular, why does your first command have the word echo twice, but then you didn’t put it into your variables?  But I guess that you want to do something like this:

Avineshwar_func() {
    git --git-dir="$1" echo test-folder/.git/ add Steps-to-follow.txt  &&  git --git-dir="$2" echo test-folder/.git/ commit
}

and then if you say

Avineshwar_func foo bar

it will be equivalent to saying

git --git-dir=foo echo test-folder/.git/ add Steps-to-follow.txt  &&  git --git-dir=bar echo test-folder/.git/ commit

Of course you can change the name from Avineshwar_func to whatever you want; e.g., git1.

Once you get this basically working, you should add error-handling; e.g.,

git1() {
    if [ -d "$1" ]  &&  [ -d "$2" ]
    then
        git --git-dir="$1" echo test-folder/.git/ add Steps-to-follow.txt  &&  git --git-dir="$2" echo test-folder/.git/ commit
    else
        echo "Usage: git1 dir1 dir2"
        return 1
    fi
}

Here's a working solution for it (RHEL 7 tested):

$ export test1='git --git-dir'
$ export test2='my-folder/.git/ add Steps-to-follow.txt'
$ #; git --git-dir'
$ export test3='my-folder/.git/ commit'
$ export git1=$test1=$test2
$ export git2=$test1=$test3
$ $git1
$ $git2

This will work. I cannot say this is the most optimal solution, however, it works the way I need and one might need it. && or ; (for firing multiple commands using one env. var.) didn't worked for me the way I expected it to work and hence I shifted to this acceptable solution for now. If someone comes up with something better or any improvement in this, please comment.
