Running a script from script (bash)
Hello
I am a UNIX noob, attempting to use Cygwin on Windows XP to build a program. I am trying to get a few scripts together that can automate some tasks and I have run into a problem.
Basically this is related to calling one script from another. I found this thread in my search but am too noob to know if it answers my problem or not, so I will explain here.
I am calling one script (say: myscript.sh) from my home directory (the script itself is in the cygwin/usr/local/bin directory). Now on one line of this script it calls another script that is on a different drive and folder (say: cygdrive/d/dev/project) and it is called winenv.set.sh.
Now within winenv.set.sh a number of environmental variables are set. But what I notice is that after calling 'myscript.sh' the environmental variables have not been set. I know it works properly if I change into that directory and run the file using: . winenv.set.sh. And that is the same line I am using in 'myscript.sh'.
If I run: bash -v myscript.sh I end up seeing the text of the winenv.set.sh file in the console.
Hopefully my explanation is clear but if not please let me know how I can clarify, and thank you for any help you can provide.

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

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. SunOS 5.11 30 Jan 2004 script(1)
