Non-regular rc files?

[Brian L. Matthews]

I've been using an old version of bash (1.14.7(1) specifically) and have
a script that creates an xterm running a command, but I want it to be
running in an interactive shell so if I kill the command, the window sticks
around so I can look at it's output or rerun the command, etc. I've
accomplished this with something like:

xterm ... -e /bin/bash -rcfile <(echo command)&

Unfortunately it appears that bash 2.x requires that the rcfile be a
regular file, as I get:

bash: /dev/fd/63: not a regular file

when I do a /bin/bash --rcfile <(echo echo hello)

So, is there any way to get bash to read an rcfile from a /dev/fd, or a
better way to create my xterms?

Thanks,
Brian
