Passing environment variables to parent shells

konndanley · #1 (**permalink**) 08-04-2007

Hi,

I am using bash and need to run a set of tcsh scripts that set environment variables. Is there a way to do this? Any help greatly appreciated.

Can you explain your requirement in detail please ????

Thanks for the response.

I use Bash, but others have written a lot of scripts in tcsh. These tcsh set a lot of different environment variables that are used to set paths, tool licenses, etc....

So, for example, if i'm in Bash, I want to run a script called 'test.csh' that contains the single line:

setenv PROJ_HOME /proj/myproj

How do I get $PROJ_HOME to be seen from Bash?

If I am in Bash, I have a C-shell script I want to run that sets an environment variable that I want, I can do this:

The file 'cshwrap' contains the line:
exec /bin/csh -c "source $1; exec /bin/bash"

Then I can just do:
. cshwrap cshfilename
