I ran into an oddity in alias expansion. I don't know if it
is a bug, or some feature I'm unfamiliar with:
Two aliases:
alias ls='ls -CFG --show-control-chars --color=tty '
alias dir='ls'
If I type "ls dir" (created a test dir called dir), I
get:
"ls dir"
I get:
ls: ls: No such file or directory.
This was "unexpected". Tracing showed:
/tmp> ls foo
+ ls -CFG --show-control-chars --color=tty foo
ls: foo: No such file or directory
---the above is "normal"---but below:
/tmp> ls dir
+ ls -CFG --show-control-chars --color=tty ls -CFG --show-control-chars
--color=tty
ls: ls: No such file or directory
---- Where the filename should have been I see dir treated
as another alias to be expanded. Huh?
I traced the cause to the ls alias -- the "space" at the
end of the alias is causing the behavior: with space,
it expands "dir" as another alias. Without the space at
the end, it works as I would have normally expected.
Is this a bug, or some feature I'm unfamiliar with?
Thanks,
