cd command, file permissions.

when you try to "execute" a directory, shouldn't it really just do a CD, considering the meaning of x permission on a dir?

Code:

hostname:/home/jameson/% ham
ham: Permission denied.

The execute permission for a directory make a user to search through that directory or make that directory the current one. But not without typing the cd command. If I remember well, such a feature is implemented in zsh, not in bash.

I can't see what command you tried to issue--is "ham" a directory or what????

If I try to "execute" a directory, it tells me the command is not found.

Execute priveleges on a directory mean that you are allowed to enter it and make changes--otherwise execute has no real meaning.

Seemed likely... zsh is pretty hip. However:

Code:

[jameson@whiteout]~% echo $SHELL
/usr/sbin/zsh
[jameson@whiteout]~% ls
Desktop  first_week  mail  scripts
[jameson@whiteout]~% scripts
zsh: permission denied: scripts

no such luck.

(scripts has 775 permissions)

setopt autocd

man zshoptions:

AUTO_CD (-J)
If a command is issued that can't be executed as a normal command, and the command is the name of a directory, perform the cd command to that directory.

dawkcid got the point: in newer versions of zsh, option autocd is set by default. You can check if you have it enabled by typing setopt without arguments.
