Change folder permissions


I created a variable:

current_folder = mkdir $(date "+%Y%m%d")

Then tried to change to folder permissions:

chmod 777 /export/home/eric/$current_folder

and got an error in a script. What am I doing wrong?

Use code tags, what error?
Hint this:
Code:
current_folder = mkdir $(date "+%Y%m%d")
Is completely the wrong syntax.

Well, I'm using a 3rd party application to run the script so it's kinda generic. When running these commands manually at the command prompt I get this error:

-bash: current_folder: command not found

I thought I was defining the variable right

No, you cant assign the o/p of mkdir to a variable like that, also no spaces around the '=' sign.
Try
Code:
current_folder=$(date "+%Y%m%d")
mkdir "$current_folder"
This assigns the output of the date command to the variable then passes the contents to the mkdir command creating the folder.

the mkidr command will also fail with an error if the folder already exists so you will need to either check first or handle the error or your script will fall over.

I figured it out:
chmod 777 /export/home/eric/${current_folder}

Except those permissions are almost certainly incorrect. My guess is that you mean either 1777 or 755 or 750, depending on who is supposed to be able to read and write the folder. Who is supposed to be able to read the folder? Who is supposed to be able to write to the folder?

If you are the only one then you'll want 750 or 700. Check the manual page for chmod and take a quick look at this page:

https://www.digitalocean.com/communi...ux-permissions

Between the two they should give an idea about how to read (and write) the permissions and get them to do what you intend.

You could also take care of it with one liner as follows:

mkdir --mode=777 $(date "+%Y%m%d")

didn't know you could set the mode at the same time you create the folder with mkdir, you learn something new every day!
