This might be more of a Linux than an IDL question, but it has been driving me crazy. I've started working on a Linux cluster, and I define aliases in a .cshrc file. One alias might be
alias lt "ls -lt"
These aliases work fine at the shell, but when I get into IDL and spawn the command (IDL>$lt ) it is not recognized.
lt: Command not found
Some additional information:
1. System aliases (those defined in /etc/profile_d) *are* recognized within IDL
2. If I spawn a child process in IDL ( IDL>$ ), then the aliases are again picked up at the system prompt.
3. I have a Linux cluster at my old job, where the aliases *are* picked up in IDL. I have yet to figure out what is different between the two Linux setups.
4. I tried using IDL83 and IDL85 in both command line mode and idlde on the new cluster, and in no case can I pick up my personal aliases. I've also tried using bash (defining aliases in .bashrc) instead of c-shell without success.
Thanks for any help. --Wayne

I sort of figured out the answer. I had a line in my .tchrc file to skip the remaining setup if not an interactive shell
if ($?USER == 0 || $?prompt == 0) exit
and the alias commands were located after this. Once you get into IDL there is no longer a shell prompt
IDL> $echo $?prompt
0
and so the shell script exited before defining the aliases. Of course, I figured this out only after posting. --Wayne
