Since we are talking about shell aliases and functions here is a
simple shell snippet that can create the directories with the modes
explicitly.
#!/bin/sh
mkdir_px() {
case $1 in */*) mkdir_px $(dirname "$1") ;; esac
test -d "$1" || mkdir -m $(stat -c %a .) "$1"
}
mkdir_px "$@"
exit $?
It is a little bit long but not unduly so.

That is the original traditional behavior of 'mkdir -p'. As Paul
pointed out in his follow-up that behavior has been in use and is now
standardized by POSIX lest some new implementation decides to do
something different from the previously implemented behavior. It is
unfortunate that it was originally implemented that way but having
done so and gotten into common use it is too late to change it now.
That is why POSIX exists is to prevent the proliferation of different
features on every system when corner case behavior like this is
found. You can pretty much guarentee that someone is counting on that
behavior if for no other reason than just by accident.

I'd like directories to be group-writable (775) by default and files to group-read-only (644) by default. Andreas suggested using ACL (setfacl -m d:g::rwx), but my file system sadly does not support ACL. Any suggestions? I'm using the following alias for directories that are created interactively: alias mkdir='mkdir -m $(stat -c%a .)' Cheers, Shaun

It makes a lot of sense. Currently all the users of my team are in one group, and so my umask is 022. I'll have to talk to my systems group about changing our practice. Cheers, Shaun

Hi Paul, I'm using an alias so that a directory is created with the same permissions as its parent: alias mkdir='mkdir -m $(stat -c%a .)' By hand I'm typing mkdir -p project/subproject Your umask suggestion is good. I hadn't thought of changing the umask in a subshell. Cheers, Shaun

Hi Bob,
I was using exactly that shell function that you described, but it
doesn't work for
mkdir -p foo/bar
I'm using the alias you gave, which works better. Thanks.
I've noticed one issue, which I feel is a bug in mkdir. When using mkdir
-pm, the specified mode is applied only to the final directory and not
the parent directories:
$ mkdir -pm 775 foo/bar
$ ls -ld foo foo/bar
drwxr-xr-x 3 sjackman assembly 4096 May 30 10:27 foo
drwxrwxr-x 2 sjackman assembly 4096 May 30 10:27 foo/bar
I would expect both foo and foo/bar to have mode 775.
Cheers,
Shaun

I don't know when 'touch' has been enhanced for '--reference' but wasn't it the same question then? Have a nice day, Berny

If your primary purpose is for an alias then you can do it this way:
alias mkdirchmod='mkdir -m $(stat -c %a .)'
alias mkdirchmod='install -d -m $(stat -c %a .)'
However a shell function might serve you better:
mkdirchmod() { mkdir "$@" ; chmod --reference=. "$@" ;}
But I think this task is better served by not doing it all and instead
using the technique of User Private Groups.

The UPG (User Private Group) technique works very well in this
situation. There is a lot of documentation available on UPG on the
net and so I won't include a specific pointer. Search for it and you
will find a lot of information on it. And different operating systems
deal with configuring it differently and so you would want to look at
documentation for your particular system. But I highly recommend
using the technique.
I generally dislike combining the functionality of several different
commands into one command. In this case combining mkdir and chmod and
I don't see any reason they can't be used individually. Plus mkdir
already allows you to create directories with a specified permission
and this is feature creep into the area of the 'install' command which
also already allows creating directories of specified permissions.

I would find it useful for mkdir to have a --reference=FILE option that works identically to chmod. My primary use case for this feature is to create a shell alias: alias mkdir='mkdir --reference=.' so that in interactive shells, new directories are created with the same permissions as their parent directory. My goal is to have directories in my personal home directory to have permission 755 and directories in my shared work space to have permission 775, so that other members of my group may create new files in shared directories. Files should have permission 755 so that members of my group cannot modify files that I've created. Thanks, Shaun
