Running scripts on AM335x EVM

KrithikChandrashekar

I've only recently started working on the embedded linux platform and I'm not very familiar with it. I'm trying to combine a set of commands into one script file to configure my wifi module on the daughter board to avoid executing each set of instructions separately . Here's a list of steps that I've done:

Created a new script file using vi editor and saved it in /usr/folder_name
Added executable permission using chmod 755 script_file_name
Tried to execute the script using ./script_file_name

But, I get an error on the last command saying that -sh: ./script_file_name: not found

The script file now juts has an echo command to spit out "Hello World", which I already ran under desktop linux but i'm unable to do so on the bash for embedded linux.

Chandrashekar,

Please include the actual commands you are using. For example, did you cd into the directory where you wrote the script file? What are the contents of the file. Without the actual commands and file it is very hard to help.

Chase,

I actually figured it out. It was merely changing the script file to reference sh instead of bash in the first line. I assumed it had bash, like ubuntu did. Thanks for your help though!

The EVM filesystem does not have bash. If you are starting your script with...

#!/bin/bash

...then you will get the error that you described. Change this to...

#!/bin/sh

... and you have to conform to sh type script commands (no bash).

Regards,

Greg
