如何在Linux上的新贵脚本中复制文件？

Question

I have a simple upstart job. I want to copy a file there when it is restarted. I can not get it to work. I have read how to execute bash scripts etc from upstart but I dont get it to work. This is what I have tried:

script
    exec bash -c 'cp /opt/test/test.log /opt/test/test.log.old'
end script

When I stop and start the service the file is not copied. Any ideas what I am doing wrong?

Answer 1

This should be run within the pre-start script tag:

pre-start script
    exec bash -c 'cp /opt/test/test.log /opt/test/test.log.old'
end script

Answer 2

Add an Upstart job:

Create /etc/init/myjob.conf

vi /etc/init/myjob.conf

with content like the following:

description "my job"

start on startup

task

exec /path/to/my/script.sh

Your script.sh file contains:

cp /opt/test/test.log /opt/test/test.log.old
