1 I am trying to create a script so users can execute a certain command as root
2 without entering a password. I thought suid was the way to do this, but I am
3 not having any success.
4
5 The command I want to execute as root is "echo -n mem > /sys/power/status".
6
7 I created a bash script (/usr/local/bin/suspendtoram) like so:
8
9 #!/bin/bash
10 echo -n mem > /sys/power/status
11
12 then set owner and group to root:root and made the script suid.
13
14 However this doesn't work. The error message goes:
15
16 /usr/local/bin/suspendtoram: line 2: /sys/power/state: Permission denied
17
18
19 I am still having to "sudo echo -n mem > /sys/power/status" and then to enter
20 a password. What am I doing wrong?
21
22 thanks
