Can a bash script detect an asterisk? [SOLVED]

[Koentje]

I just solved it myself. Awk can't search for astrix, so i changes it with sed to ^. Then awk print $1 and awk print $NF.

Code: Select all

xrandr | sed -n "/^$ports/,/^[^[:space:]]/p" | grep '*' | sed 's/*/^/g' | awk -F'^' '{print $1}' | awk '{print $NF}'

In a bash script

Code: Select all

#!/bin/bash

while read -r ports
do

   freq=$(xrandr | sed -n "/^$ports/,/^[^[:space:]]/p" | grep '*' | sed 's/*/^/g' | awk -F'^' '{print $1}' | awk '{print $NF}')
   reso=$(xrandr | sed -n "/^$ports/,/^[^[:space:]]/p" | awk 'sub("*"," "){print $1}')
   echo -e "$ports\t$reso  $freq"
   
done < <(xrandr | grep -w 'connected' | awk '{print $1}')

The script only searches for connected ports.

Output

Code: Select all

$ ./monitors.sh
DisplayPort-1	3440x1440  143.97
HDMI-1-1	1920x1080  60.00

So you got it from xrandr, thanks.

[Coggy]

What does the + mean?

I think it means it's xrandr's recommended setting. So it is nearly always the same as the * which indicates the current setting.

Are some of youse big-brains making your own conky widgets based on my idea???

Holy crap!
