Diff Paste is an interactive Bash script to call a diff tool with pasted (or typed) content.
I wrote it because I have frequently found myself wanting to paste two short (or not so short) snippets of text into a Bash shell and see whether they are different.
$ ./diffp
Paste or type the first text now (press Enter, Ctrl-d when done):
this is a
short story
about a bat and a dog
who go on
adventures
Paste or type the second text now (press Enter, Ctrl-d when done):
this is a
short story
about a cat and a dog
who go on
adventures

-----------------------------------------------------
3c3
< about a bat and a dog
---
> about a cat and a dog
-----------------------------------------------------
| < this line came from your first input |
| > this line came from your second input |
-----------------------------------------------------
Or when the snippets are identical:
$ ./diffp
Paste or type the first text now (press Enter, Ctrl-d when done):
a cat
Paste or type the second text now (press Enter, Ctrl-d when done):
a cat
-----------------------------------------------------
| Your diff taken at 10:33 (1573662793) starts here |
-----------------------------------------------------

| No diff. Inputs were identical. |

Download the diffp file and put it somewhere.
You may need to make it executable with chmod +x diffp.
I recommend putting it somewhere on your path, like in /usr/local/sbin/, so that you do not have to be in the same directory to call it.
