Unable to execute a shell script in android shell

Question

I am trying tun a shell script from android shell. Please see the output below.

root@user:/data # ./run_script.sh
/system/bin/sh: ./run_script.sh: No such file or directory

root@user:/data # ls -l run_script.sh
-rwxrwxrwx root     root         5861 2016-11-14 07:31 run_script.sh

Why is it saying "No such file or directory" The error is strange as the file is actually present.

I tried copying the same shell script to /system partition as well. The result is same. I verified from mount command that both the partitions are not mounted with noexec flag.

I am able to get it working with sh run_script but I want to get it working by executing directly.

Yes 777 are the permissions. In the code snippet i showed the permissions — Sandeep

Usually this happens when a shebang is not correct. Check if you have a "#!..." at the start of the script and remove it or correct it

you have to remove it or put: "#!/system/bin/sh" (no quotes)

Thank you so much. It worked.. I have one more query.. My script is a big one. In the middle of execution I see an error as follows "./run_script: //: can't execute: Is a directory" error. Any Idea why do we see this

Looks line it's trying to execute a directory, you might want to run it as "sh -x run_script.sh" : "-x xtrace Write each command to standard error (preceded by a ‘+ ’) before it is executed. Useful for debugging.his will print out in "debug" mode" and see exactly what's going on.
