$(which cd) returns /usr/bin/cd and that file contains the script I displayed
yesterday. I do not have my MBP here at work today so I cannot obtain the
other informations you desire.
In any case, once the reference to aliases twigged my memory I tested for the
problem with other accounts and discovered that the issue existed only for my
development user id. That brought to mind that I once had RVM installed on
that account. Further, I recalled I once had run into a bug with an early
development version of RVM due to it overriding cd in a shell function, which
is not an alias but is similar enough for most purposes. I cannot recall what
that issue was but at least the memory of it put me on the right track.
So I grepped for CD in ~/\.* and found an RVM related cd function in
.bash_profile which did not escape $1. I changed that reference to "$1" and
the problem was thereby fixed.
Thanks for all the help and suggestions.
I do have a few residual questions however:
1. What does the 1+ in the shell expansion ${1+"$@"} mean and do?
2. I know that $0 returns the shell name or shell script file name. How does
${0##*/} differ in effect from $0.
3. Why is ${0##*/} used instead of $0 or ${0} in this case?
