There is a chmod command to set file permissions, but can I get file permissions in octal mode (such as 755) from the command line?
You can try
stat -c "%a %n" *
Replace * with the relevant directory or the exact filename that you want to examine.
From the man page of stat,
-c --format=FORMAT
use the specified FORMAT instead of the default; output a newline after
each use of FORMAT
%a Access rights in octal
%n File name
Usage:
With files:
$ stat -c "%a %n" ./Documents/Udev.html
664 ./Documents/Udev.html
With folders:
$ stat -c "%a %n" ./Documents/
755 ./Documents/
