Pipe echo of associative array into dmenu
Clash Royale CLAN TAG#URR8PPP
1
I have this script:
#!/bin/bash
declare -a arr
arr+=(
[mirror]="xrandr --output hdmi-1 --same-as edp-1"
[extend]="xrandr --output hdmi-1 --auto"
)
screen=hdmi-1
chosen=$(echo -e $!arr[@]| dmenu -fn monospace-14)
[ "$chosen" != "" ] || exit
But when I run this, mirror and extend are the same item.
Is there a way to get this into two separate items?
To print multiple items you do this:
echo -e "firstnsecondnthird" | dmenu
I used an associative array because then I only need to write the options once, and adding options is very easy (just append the list).

Shouldn't it bedeclare -A(upper case) for an associative array (as opposed todeclare -afor an indexed array)?

+1 That is so amazingl! I never heard about declare -A before. I am feeling like a idiot for all scripts that I wrote without knowing about that. So that is the OP's problem.

Are you wanting to use
bash or sh? Your code explicitly uses sh but the question is tagged bash. Please clarify. n. b. I'm pretty sure sh does not have associative arrays.– DopeGhoti
