I didn't do it!

Jot it down

For testing purposes, I usually create a series of files to run my bash scripts against and I love using the jot command.

jot 3

Generates:

1
2
3

Awesome! This allows me to:

jot 8 | xargs touch

I also use it to generate random series of numbers:

jot -r 10

What if you want to specify a range of numbers to which the randomisation occur?

jot -r 10 580 900

The above gives you 10 random numbers between 580 to 900. Awesome, right? Then there’s more - you can prepend a word to it!

jot -w file_%d -r 10 580 900

Like I said, I love the jot command. There’s a lot more use of this nifty little command. I only cover those I use often.

For the rest of it, you can go through the tutorial here.
