Bash script - ENV Variable context problem using su
Hello
I have found some piece of code to verify and then run shell script with root permission from normal user.
see : http://blog.mecworks.com/articles/20...script-as-root
I have wrote two scripts using this tips.
- one to copy file from server to local computer ( files_copy_from_server.sh )
and this program is started by using another script ( files_copy_from_server_launcher.sh)
- one to copy file to server from local computer ( files_copy_to_server.sh )
and this program is started by using another script ( files_copy_to_server_launcher.sh)

The second one failed because variables are not set correctly :

Code:
user@asus:~> /home/user/bin/files_copy_to_server_launcher
CMD   : /home/user/bin/files_copy_to_server
PARAM : /home/user/bin/files_copy* /root/bin/
