I've to run a .csh script from a bash shell, to accomplish this I'm using tcsh -c <command> command but with that I also require environment variables defined in parent bash shell. Could someone suggest a way to export environment variables from bash to tcsh. I would like to have the below structure for my command.



$ tcsh -c "env ENV_VAR=${ENV_VAR} /command/to/run <args>"





bash tcsh

    Environment variables are inherited automatically, you don't need to do anything special. That's the definition of environment variables.

  • You don't need to use tcsh -c to run a csh script. If the script begins with #!/usr/bin/tcsh it will be run with tcsh.

  • tcsh -c <command> executes <command> as a tcsh command, but that doesn't affect how the scripts within it are executed.

Just add the variables to the environment of tcsh; the script will inherit them from tcsh. (I'm assuming /command/to/run is a C-shell script.)



$ SOME_VAR="some value" tcsh -c "/command/to/run <args>"


Assuming the argument to -c isn't some more complicated C-shell expression, you can dispense with the option.



$ SOME_VAR="some value" tcsh /command/to/run <args>
