How to put the output of a shell command into a variable

TCH · 11 July 2021, 16:26

In UNIX you can use shell substitution for this purpose, like

KECSKE=`cat kecske.txt`

or

KECSKE=$(cat kecske.txt)

. How is this done in AmigaShell? I know the commands

type

and

set

, but how do i connect them together?

Code:

set KECSKE <result of "type kecske.txt" should be here>

I cannot find any info about this. Is this even possible in the AmigaShell? At least with a trick?

Try this:

Code:

set <var> '<command [args]>'

So, substitutions are done via the apostrophes. Thank you very much.

Edit: But this is only works at the prompt, not in a shell script.

Edit 2: Okay, they were reverse apostrophes, so the backtick works just like in UNIX.
