Spawning Unix commands from IDL under bash [message #93307]

I've recently succumbed to peer pressure to switch my (Mac and Linux) shell from tcsh to bash.

Everything is working fine except that I do not have access to the aliases defined in my .bash_profile (Mac) or .bashrc (linux) files when spawning from IDL. For example in my .bash_profile file I have

alias ll="ls -l"

I am able to use this alias at the system prompt but it is not recognized when spawning from the IDL prompt

IDL> $ll (or IDL> spawn,'ll' )
bash: ll: command not found

Note that this is not a PATH problem and IDL> spawn,'ls' does work.

A google search revealed a user asking a similar question 10 years ago
https://docs.astro.columbia.edu/ticket/160

and the "solution" was to use tcsh instead of the bash shell. But there must be some way for bash users to get the same behavior issuing a command from SPAWN within IDL, that they do when issuing the command from the system prompt.

Thanks, --Wayne
