How do I do this in one line reusing and reversing the arguments? Also what’s the syntax to create a function that will do this?
mv newname.js oldname.js git mv oldname.js newname.js
for example to make a folder then cd into it you
mkdir new-folder-name && cd $_
is it something like mv newname.js oldname.js && git mv $2 $1

have you considered writing a script? It is fairly simple, and you can add variables when you run it.
just create a text file, save it with whatever you want to name it, and then make it executable with:
chmod +x file-namea quick example of a script, which I can pass two variable to when I run it:
#!/bin/bash echo $1 echo $2 exit 0now if I run that script like this:
file-name "first variable" "second variable"it should echo:
first variable second variable
awesomer.
One more fun step: you can make a line in your .bashrc file (if you dont have a .bashrc file, just create a file called .bashrc in your users home directory)
add this:
reload your bashrc:
and now you can run this:
thanks, I made the file github.com/gdi2290/git-mv on github
