Modifying Path in IDL in Bash Shell?

[hobbies4kk]

Hi,

I'm a newbie to Linux and am attempting to modify my pathway in IDL to allow me to run a data reduction package in IDL. The directions for this this process are given for a .cshrc file, but I use a Bash shell. How can these directions be modified to allow me to use them? I've included the directions below. Thanks. -Kathy

Edit the .cshrc file to include the line

setenv IDL_PATH +/packagedirectory:$IDL_PATH

where /packagedirectory is the path to the package directory
(e.g., /scr0/irtf/Spextool).

If there is no IDL_PATH defined in the .cshrc file, then include the
line

setenv IDL_PATH +/packagedirectory
