Severity: normal
I was trapped by this strange bug. It seams that wildcards ("?" and "*")
are not resolved when used in redirection.
If I use the following in a script with sh (dash), it tries to write to
'/sys/class/leds/0003:17EF:6009.000?:amber:mute/brightness'.
#! /bin/sh
set -x
DEVICE=0003:17EF:6009.000
echo 1 > /sys/class/leds/${DEVICE}?:amber:mute/brightness
The following will work correct:
#! /bin/sh
set -x
DEVICE='0003:17EF:6009.000'
MUTE="$(echo /sys/class/leds/${DEVICE}?:amber:mute)"
echo 1 > $MUTE/brightness
With other shells (zsh or bash) both snipplets does the same.
