Git Alias - Multiple Commands and Parameters

Question

This will work (tested with zsh and bash):

[alias] chs = !git checkout $1 && git status

This targets Windows batch / msysgit bash; might not work on other environments.

As Olivier Verdier and Lily Ballard have said

[alias] chs = !git checkout $1 && git status

almost works, but gives a spurious extra insertion of the argument ...

git chs demo -> git checkout demo && git status demo

But if you add && : to the end of your alias, then the spurious argument is consumed into a location tag.

So

[alias] chs = !git checkout $1 && git status && :

gives the correct output ... git chs demo -> git checkout demo && git status

You can define a shell function.

[alias] chs = "!f(){ git checkout \"$1\" && git status; };f"

I was able to create multi-line and quite complex git aliases. They work fine on Windows but I assume they'd work elsewhere too, for example:

safereset = "!f() { \
                trap 'echo ERROR: Operation failed; return' ERR; \
                echo Making sure there are no changes...; \
                last_status=$(git status --porcelain);\
                if [[ $last_status != \"\" ]]; then\
                    echo There are dirty files:;\
                    echo \"$last_status\";\
                    echo;\
                    echo -n \"Enter Y if you would like to DISCARD these changes or W to commit them as WIP: \";\
                    read dirty_operation;\
                    if [ \"$dirty_operation\" == \"Y\" ]; then \
                        echo Resetting...;\
                        git reset --hard;\
                    elif [ \"$dirty_operation\" == \"W\" ]; then\
                        echo Comitting WIP...;\
                        git commit -a --message='WIP' > /dev/null && echo WIP Comitted;\
                    else\
                        echo Operation cancelled;\
                        exit 1;\
                    fi;\
                fi;\
            }; \
            f"

I wrote a post and have a few more examples here.

[alias]
chs = !git branch && git status
