setfacl script

[ibaboom]

Good day

I have a question on how to create a script to setfacls on another system. I have the output from getfacl, on the new system the file system does not exist. I would like to create the file system and set the acls at the same time. Any suggestions would be greatly appretiated.

Here is what the output of the getfacl looks like.

# file: somedir/
# owner: lisa
# group: staff
user::rwx
group::rwx
other:---

I need to create all of the directories and subdirectories listed in the file. I know that I can use setfacl --restore=myfile to set all of the acls. But how would I go about creating all the directories.

Thanks a lot

Actually the script needs to create directories with the owners and groups.

How would I do such a task.

Thanks

You would have to scan myfile for 'file:', extract the directory name, and create the directory using mkdir.

grep 'file:' myfile | awk '{print $3}' | xargs mkdir

Then you would:

setfacl --restore=myfile

That should set the owners and groups as well. It does on my RHEL4.

Cool, but if I ran that as root wouldn't it create all the directories as root:root

As I said "That should set the owners and groups as well.". You'll just have to try it like I did.

• Create a directory
• Use getfacl to save the ACL information
• Change the owner and group on the directory to something else
• Use setfacl with the --restore option to see if it changes them back

Awk is complaining about a syntax error for the print statement.

Sorry but I can't help you unless you post the commands that you typed in and the exact error message that you got.

Hey thanks for your help! I realized the error was I used parenthasis() insted of brackets {}

I actually wrote a perl script.

open(FILE,"@ARGV[0");
while (defined ($line = <FILE>)) {
chomp $line;
if $line =~ /mydir/) {
$directory = substr($line, ;
}

mkdir $directory, "\n";
}


But your solution is much more to the point!
