It does appear rather useless. Curiously, Debian (checked on Wheezy =
bash 4.2+dfsg-0.1+deb7u3 and Jessie = bash 4.3-11+b1) seems to not
supply anything like that, so it would appear to be some kind of
Fedora-ism rather than a part of anything upstream; that, or the
Debian folks are actually paying attention to what they ship onto
users' systems. lu$ cat /bin/cd
#!/bin/sh
builtin cd "$@"
lu$
But doesn't this change the current dir only in the child shell?
Which then exits right after the second line, parent shell's $PWD
unaffected. I really don't see how this script is useful.
