Change folder permissions in Windows Solved

Question

Hello,

I hesitated before putting this message in the Windows section, but I think it's the best solution.

So here it is, I want to modify the permissions of a folder (which happens to be C:\Program Files) so that any authenticated user of a domain (this part is already configured) can have write rights in addition to read and execute rights.

Note that it's not modification rights but strictly write rights.

I want to emphasize that the rights are only applied to this folder and not recursively!

So far, no major problem. I'll be told, "Go to properties/security/etc..."

My issue is that I need to do this via command line with DOS.

And there, I can't find a solution...

Thanks in advance if you have any ideas.

Configuration: Windows XP SP2

Click the Start button. Type the command cmd.
Right-click on the cmd.exe command and select Run as administrator.
Then enter the command takeown /F folderpath /R, replacing folderpath with the full path of the folder you want to take ownership of, for example takeown /F C:\MSOCache /R. Press Enter to validate.
You will then take ownership of the folder and all its contents (files and subfolders).

Hello

The chmod command allows you to modify access rights on files or directories. Only the owner of the files or directories (or root) can perform this operation.

There are 2 methods: symbolic or octal.

Symbolic method

chmod ugoa|+/-/=|rwxugo file

The parameters of chmod break down into three parts:

*
the 1st indicates to whom the modification of access rights applies:
o
u for the user, the file owner (u for user)
o
g for the group (g for group)
o
o for the rest of the world (o for others)
o
a for all (a for all)

*
the 2nd is a character +, - or = :
o
+ means adding new access rights
o
- means removing access rights
o
= means exclusively granting the specified access rights

*
the 3rd indicates the concerned right(s):
o
r for read (r for Read)
o
w for write (w for Write)
o
x for execute (x for eXecute)
o
u,g,o to refer to the rights of owner, group, other users

Some clarifications valid in the case of a directory:

*
r means total read access to the directory (the ls command lists, for example, all files contained in the directory). But in the absence of this right, it is still possible to read a file contained in this directory (by knowing its path).
*
x means the right to open the directory. To prevent "traversing" a directory, this is the right that needs to be removed.

Examples:

chmod g+r file ### allows the group to read the file
chmod u+rw,go+r file ### allows the user to read and write the file, and others to read it
chmod g=u file ### allows the group to have the same rights as the user

Octal method

chmod XXX file, where XXX = User | Group | Others (X represents an integer between 1 and 7)

Value of the digit X:

*
0: no rights in reading, writing, executing
*
1: execution right
*
2: write right
*
4: read right

Different rights can be accumulated: X = 7 (i.e. 1+2+4) means therefore that all rights are given on the file.

In summary X = Read (4) + Write (2) + Execute (1)

*
The 1st digit X specifies rights for the file owner.
*
The 2nd digit X specifies rights for the group owner of the file.
*
The 3rd digit X specifies rights for all other users on the file.

Thus, chmod 777 file grants all rights to everyone.

A chmod calculator is available at http://pages.infinit.net/glopglop/local/chmod.htm

Example:

chmod -c 644 /home/user/text.txt ### modifies the rights to rw-r--r-- for the text.txt file meaning that only the
owner can write and others can only read

man chmod ### to get all the options on "chmod"

Good luck

I would have really loved to be able to use a Linux infrastructure to take care of that...

My issue... well, it's that we are operating on Windows here. So everything has to be run with this operating system.

Otherwise, I wouldn't have hesitated and I would have already used chmod.

Does anyone have a Windows solution to suggest? I haven't found any since this morning...

Dacarn · Answer

A little bump to say that even a calculator doesn't work for this kind of thing...  A bit of help or I'll give up for good and have to bother all 150 users of the network one by one?

I will try to look for that, but I don't have many ideas.

One possibility that was suggested to me by a colleague is to use Cygwin in order to have access to a Unix shell...

However, it's a software that I find a bit too heavy for my taste and it will take a long time to install on all the machines.

Nevertheless, if I don't find other solutions, that will have to do.

Dacarn · Answer

After extensive research, I have found a solution that I am still studying the applications of.

Indeed, modifying permissions via command line in Windows XP is not included in the standard commands.

The Cygwin solution does not work either.

You must use the SetACL utility, which is an external program under GPL license.

It can be downloaded and installed at the following address:

With a bit of searching, there are numerous explanatory examples available.

Personally, after a Windows migration, I no longer had write access to my files due to the change of ownership, Changing the owner of a Windows file solved my problems. For the commands, it discusses ICACLS and TAKEOWN.

So, what about SetACL.exe?
