Linux Script
Posted on 2012-12-22
I'm trying to add these requirements to my script below:
o The file owner can read, modify and access the scenario company directories
o The group members can read and access the scenario company directories
o Everyone else has no access.
· Create a file in each of the scenario company directories.
o Set the file permissions for the files in the scenario company directories.
o The owner can read and modify the file
o The group members can only read the file
o Everyone else has no permissions

Hi,
Your requirements require you to customise directory and file permissions before running the script. It is not a part of the script.
A directory should have this if you want the owner can read write and group can read write and others won't have any permission:
While if ypu want the group can only read but can't write the directory should have this:
Cheers,
K.

chmod 770 /Path/to/directoy

chmod 750 /path/to/directory

1-3) Add "umask 027" before creating directories (at line 13, for example)
4-7) Add "umask 026" before creating files
Then do something like
touch /ARI/SALES/REG_1/MYFILE
for each of the desired directories.
Since you said it's a Linux script change all backslashes (the Windows directory separator) to forward slashes (which is the standard Linux directory separator)
Tip: When using "mkdir -p ..." the full path will be created if it doesn't already exist, so you can spare all the stuff in the first lines 14-21.

Thanks what is the unmask command do? How do I add to my script. For touch, i can use that and remove mkdir?

"umask" sets the file/directory creation mask.
Issue "umask" on the command line to check the current setting.
By default, a newly created file has permissions 666 (rw-rw-rw-) and a newly created directory has 777 (rwxrwxrwx).
The value set in the umask is subtracted from this default, so a file created under umask 026 will have permissions 640 (rw-r-----), and a directory created under umask 027 will have permissions 750 (rwxr-x---).
Add it to your script as a regular statement in a separate line:
...
umask 027
mkdir ...
mkdir ...
...
umask 026
touch ...
touch ...
...
When the script exits the umask will be reset to its default value "022".
"man umask" for more.
"touch" does not replace mkdir. It just creates the named (empty!) file, resp. (when used without flags) sets its last modification timestamp to the current time if the file exists.
You can remove the statements meant to create the top level diectories when using the "-p" flag of "mkdir"
So
mkdir –v -p /ARI/MARKETING/FT
will create /ARI, /ARI/MARKETING and /ARI/MARKETING/FT if neither of these directories already exists, but will leave existing directories alone (means: it will not destroy and recreate these directories).

Yes, looks good.
I think the ">" character in the message string in line 14 is a typo, right?
Not that it will do any harm, I just wanted to mention ...
The error messages in lines 20/21 need customizing to contain the correct directory name.
Seems you don't want to use "mkdir -p ...", but that's of course your decision.
