bash 脚本返回状态 -13

Question

Scenario: Below are two scripts where a bash script is invoked by python script.

test.py

import subprocess
p=subprocess.call(['bash','test.sh'])
f = open("demofile2.txt", "a")
f.write(p)
f.close()

test.sh

echo "hello world"

observation: works fine when the test.py is executed directly.

issue: when I create demon under /service to run the file. The value of 'p' (return of call) is -13.

Note: The user:group for both script is root. I am using centos8

Answer 1

If anyone has same problem, the answer lies in the resolution of the path.

When I to execute the python script in the command line, it was able to locate the script. But when the demon tool (even systemd) runs the script it was not able to locate the bash script. When I provided absolute path of the bash script(opt\test\test.sh) in the python script,it worked.

\opt\test\test.py

import subprocess
p=subprocess.call(['bash','opt\test\test.sh'])
f = open("demofile2.txt", "a")
f.write(p)
f.close()

\opt\test\test.sh

echo "hello world"
