Launch doesn't work

[oss-linux-etc]

This is with default settings.

bash: line 1: cd: too many arguments
bash: line 1: ./backup: No such file or directory
Exit code=127
Press enter to continue...

Is there any documentation how to use launch and run configurations?

When you started a script in "run" or "debug" mode it is available as a new launch configuration - standard eclipse behavior.

Just Open "Run->Run configurations" and search for the created configurations.

By the way: I think the bash output is from your script - you should try to call the script directly from a terminal and check if the problem exists.
