Setting environment variable using shell script
Hi All,

I'm trying to write an menu driven program to automate some functions which involve loging to multiple hosts. The hosts can differ for every use, so I thought I would use an config file to get the hostnames. Now I need to set those values in the config file to environment variable to access by the menu script to login and proceed with the functions.

I tried to execute the config file from the shell script, but the environment variables are dying after the menu script is exited. The question is how to set those environment variable in the terminal for the complete session even after exiting the script, because if the menu gets failed in the 2nd or 3rd step and when the user tries to execute the script again it is mandating the user to run the config file inorder to set the env variables which is a pain for the user.

Please give your suggestions !!!

Thanks,

makesh

MAKESH(1)						      General Commands Manual							 MAKESH(1)

NAME

       makeSH - a .SH script maker

SYNOPSIS

       makeSH files

DESCRIPTION

       MakeSH  examines  one or more scripts and produces a .SH file that, when run under sh, will produce the original script.  The .SH script so
       produced has two sections containing code destined for the output.  The first section has variable substitutions performed  on  it  (taking
       values  from  config.sh), while the second section does not.  MakeSH does not know which variables you want to have substituted, so it puts
       the whole script into the second section.  It's up to you to insert any variable substitutions in the first section for any values you want
       from config.sh.

       You  should  run  makeSH from within your top-level directory and use the relative path to the file as an argument, so that the "Extracting
       ..." line printed while running the produced .SH file later on will give that same path.

BUGS

       It could assume that variables from metaconfig's Glossary need to be initialized in the first section, but I'm too lazy to make it do that.
