无法在Android Shell中执行Shell脚本

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.

Answer 1

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

Answer 2

file format reason maybe you create file in windows,then push it to phone. cat command ,can not see it. use vi,we can see

!/bin/sh^M

ps^M
