File permissions - UNIX for Dummies Questions & Answers

Is there any way that I can use the ls command to view the permissions that a group has on a file.

I know ls -l file1 will list all the permissions for file1.
Would I have to use the following command: ls -l file1
Then grep or sed the output to retrieve what permissions the group has.

Got it

ls -l file1 | cut -c 4-6

Is there a more efficient way?

Not really. You can write a short shell script and then alias the script - if by "efficient" you meant a simpler user interface.

How do I assign the results to a variable.

I have tried the following but it doesnt work

TMP= ls -l file1 | cut -c 4-6

This just seems to output the file permissions to the screen, whereas I want the result stored to TMP so that I can perform an If statement on it.

*Note the backticks I inserted.

Code:

TMP=`ls -l file1 | cut -c 4-6`
