linux - Cut and tr: command not found

Question

Whats wrong whit this code:

#!/bin/sh
PATH=/sbin:/bin

. /lib/init/vars.sh
. /lib/lsb/init-functions

 HOSTNAME="TAI-$(ifconfig | grep "HWaddr" | cut -d" " -f11 | tr -s ":" "-")"

Then:

root@teste:/ ./hostname.sh <enter>

The script return:

./hostname.sh: 7: ./hostname.sh: cut: not found
./hostname.sh: 7: ./hostname.sh: tr: not found

But in console (command line) run perfect.

root@teste:/ HOSTNAME="TAI-$(ifconfig | grep "HWaddr" | cut -d" " -f11 | tr -s ":" "-")" <enter>

root@teste:/ echo $HOSTNAME <enter>
root@teste:/ TAI-b8-27-eb-81-4f-c5  - It's OK.

Someone could help me please?

Thanks a lot.

Look at the line:

PATH=/sbin:/bin

cut and tr are in /usr/bin , which is missing from your PATH. Add :/usr/bin to the end of the PATH variable.

PATH=/sbin:/bin:/usr/bin
