Question

How do I reuse previous arguments in reverse order in Bash?

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

This question was answered by @sierracircle:

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-name

a quick example of a script, which I can pass two variable to when I run it:

#!/bin/bash

echo $1
echo $2

exit 0

now if I run that script like this:

file-name   "first variable"  "second variable"

it should echo:

first variable second variable
