Write portable Git aliases

Question

The following aliases return all the same number of results, on my Cygwin (on Windows):

file-history1 = log --
file-history2 = log
file-history5 = "!f() { git show -s $(git rev-list --date-order HEAD -- $1); }; f"
file-history6 = !sh -c 'git show -s $(git rev-list --date-order HEAD -- $0)'

But what would be the best / worse ones in there?

I'd like to write portable aliases, that will work similarly on Windows (Cygwin or Git Bash) / Linux / MacOS...

I do have a favor for #5 and #6 as they show that they expect an argument. But that would be disregarded if they don't execute properly on other platforms...

Answer 1

Ignoring other requirements or needs you might have (like what @ades mentions in the first comment) I'd vote for option 2: file-history = log

I'd say that for the sole reasons that

1. It is simpler
2. It has no dependencies

As a rule of thumb I've learnt the painful hard way, is simpler means less chance of breaking, lower maintenance/debug costs, easy of understanding for you later or other people, portability, ...

So, if it works for you given any other requirements, I'd say go with the simplest, which looks like (2).
