Top Forums Shell Programming and Scripting Running a script from script (bash) Post 302271496 by bobban on Friday 26th of December 2008 01:20:58 AM
Old 12-26-2008
Here is the solution for those who come across this thread in the future.

The problem in a nutshell is that a script itself runs in a sub-shell, so setting environment variables in that script only sets them in the sub-shell (which is destroyed when the script finishes). The solution is to run the script using the 'source' command which allows the script to change the environment variables in the calling shell.

In my case, I am calling a script that calls a script that sets environment variables:

source myscript.sh

- and myscript.sh will contain a line: source winenv.set.sh


note that a period can be used instead of 'source'.

. myscript.sh

. winenv.set.sh

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
