I would like to know how to call one script from another and the return the value of the called script to the calling script for further processing?(in bash)
To call a script, simply issue the command as you would type it at the normal prompt.
The above are simplified, but hopefully show you the simple logic. The last line of 'exit 0' ends the program and returns an error code of 0.
Before my '#say good-bye' line, I could check for a returned value, with somthing like:
So, you can pass something back as part of the error-handling ability of master programs and called programs.
Otherwise, the only other effective way I know of to pass data from a called program back to the master program is to write the information to a temporary file.
