There has been a number of old threads on this but non looked like
they worked
I have a shell env varible and a file that has a generic name. The
resolved shell var needs to be substituted in that spot:
setenv FILENAME /path/to/myfile.txt
the file has some text:
I need to subtitue FILENAME
end result:
I need to subtitue path/to/myfile.txt
Thanks
