Display permissions in octal format
Hi,

Is there any way to display the permissions in octal format rather than "rwxrwxrwx" format.

I have a file and i want to see the permissions in octal format. Please help.

Okay this is working .

i checked one file with permissions -rw-r--r-- and this code is showing it as 100644.

Can any one explain what 100 means here ??

you need to add the bitwise AND

Code:
perl -e'printf "%o\n",(stat shift)[2] & 07777'


from the perldoc

Quote:
Because the mode contains both the file type and its
permissions, you should mask off the file type portion and
(s)printf using a "%o" if you want to see the real permissions.

On many Unix/Linuxes there is perl basically installed. Did you try it?
