Hey guys,

I have been trying to write a shell script which is able to run a little programm.

ping -c 2 192.168.1.51
if [$? !=0] ; then
wol --host=192.168.1.1 90:50:A1:EF0:53
echo "Starting up Host"
fi
Thats what I got so far. What I want to do is that the script pings one of my computers in my network.
Whenever it fails I want the script to start the program "wol" which starts up the remote computer by the wake on lan function.

I am a noob in shell programming so it is a minor error most probably. I guess the line

wol --host=192.168.1.1 90:50:A1:EF0:53

has to be different. It is the whole command which has to be executed.

Thx

You do not need to post your question twice but you need to tell us what the problem is !

Hey,

I am sorry for double posting. My firefox had some trouble sending my post!

The problem is that whenever I execute the script it says

line 4 command not found. Line 4 is
wol --host=192.168.1.1 90:50:A1:EF0:53

Thx

Is this bash scripting ?
Isn't the real error message:
"wol: command not found"
Assuming int, the "wol" command is either missing or not in the path.

Hey

yeah it is a bash script.

And you are right it cannot find the command. I just want to know how I write a sript that can execute a program.

When I type "wol" in the command line it executes the programm "wol".
Do I have to specify the path of the programm or what?

Thx

Suinatsa

what is your path ? (echo $PATH)
where/what is wol ? (type wol)
that's one possibility, another would be to set a correct PATH.

Hey

ok wol is a program which uses the (w)ake (o)n (l)an function. Whenever you execute the program with some parameters it starts up a computer in a network.

What I want to do is that whenever I execute the script one computer in my network starts up.

I never specified anything for $path so it does not show me anything if I do echo $path.
Thats why I asekd if I have to do it!

Thx

I already know that, please answer my question which was:
run both of the following shell commands, and post their output:
You do not start the network, which must be already up, but really boot-up a connected host.
I didn't asked you about $path but $PATH, which is usually set even if you're not aware of.

Hey

I am sorry but I am a noob in shell coding!

Ok I ran the commands:

/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/games:/opt/www/htdig/bin:/usr/lib/java/bin:/usr/lib/java/jre/bin:/opt/kde/bin:/usr/lib/qt/bin:/usr/share/texmf/bin
wol is /usr/local/bin/wol

Thats the output.

Thx

Are you running your script directly from the bash command prompt, or do you have it setup to run from something like a cron script. Usually the PATH variable that is set when running a cron script is different from a user's bash prompt. Explicitly specifying the path to wol might help. (e.g. /usr/local/bin/wol)

Can you post the whole script code too ?
Or add "echo $PATH" before the "wol" command is attempted and see if /usr/local/bin is there.
