I'm running a script which is triggered by the kernel object of device attachment. The purpose of the script is to run one of the commands that are loaded with the device and grep a certain line which prints the firmware version. When I lookat the log I get the following errors: "command": not found. My issue here is that when I run this script manually, everything seems to work, and that "command" is found and works properly. I also included 60 seconds wait time so that this module/drivers would be loaded by that time (just in case), which seems not to help since the script is executed after drivers are loaded anyways. Any help would be appreciated, thanks!

It depends on the script. The script is triggered not by your shell which has your path and environment information, but other path and environment information. Echo out the environment information to a debug log file when the script runs.

Check that against what you have in your user environment.

You also need to get to the bottom of what command is not being found. Do you get a line number? Or is the script one line only? Either case, find out what command is being rejected.

A final point is that for most scripts I include the full pathname for all executable commands.

Instead of "ls" I use "/bin/ls" because ls is located in the /bin directory. If you're unsure, when in your shell, perform to get the path for the command you're running from within the script and then place that path into the script file.

to help debug try issueing an echo $PATH from within your script and compare it with the output of the your $PATH variable. try using the /path/to/program from within the script to ensure it can find the command.

You are being too secretive... Loading kernel-modules / attaching hardware doesn't add new commands to the shell or installs new executable binaries, so please try to explain what are you actually talking about.

Interesting. Are you running Android? I'm just starting to learn more of it so please add more details.

Are you using a udev rule?
