How to make a program that finds id's of xinput devices and sets xinput some settings

Question

I have a G700 mouse connected to my computer. The problem with this mouse in Linux (Ubuntu) is that the sensitivity is very high. I also don\'t like mouse acceleration, so I

You can do something like the following.

if [ "$SEARCH" = "" ]; then 
    exit 1
fi

ids=$(xinput --list | awk -v search="$SEARCH" \
    '$0 ~ search {match($0, /id=[0-9]+/);\
                  if (RSTART) \
                    print substr($0, RSTART+3, RLENGTH-3)\
                 }'\
     )

for i in $ids
do
    xinput set-prop $i 'Device Accel Profile' -1
    xinput set-prop $i 'Device Accel Constant Deceleration' 2.5
    xinput set-prop $i 'Device Accel Velocity Scaling' 1.0
done

So with this you first find all the IDs which match the search pattern $SEARCH and store them in $ids. Then you loop over the IDs and execute the three xinput commands.

You should make sure that $SEARCH does not match to much, since this could result in undesired behavior.
