Pathway Modification in Bash?

[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

export IDL_PATH='/path/to/IDL:$IDL_PATH'

Note that bash doesn't read .cshrc, bash use the files .bash_profile and .bashrc.

The syntax for setenv VAR value:$VAR in bash is as lordnothing writes.
export VAR="value:$VAR"

Hi lordnothing,

Thanks for your reply. But how does

export IDL_PATH='/path/to/IDL:$IDL_PATH'

specifiy the path of the external package that I'm attempting to use? (The command for the .cshrc file was setenv IDL_PATH +/packagedirectory:$IDL_PATH )

Also, how would the line setenv IDL_PATH +/packagedirectory
read in my .profile file?

Thanks very much. -Kathy
