What that means is you are "finding" files with specific permissions. For example find / -type f -perm -0002 is going to find any files (the type f sets this, use d for directories) that are world writable. The 4 numbers following the -perm are the same as chmod's perms. Do a man chmod to get a full listing. On Thu, 2004-09-09 at 07:24, Chadley Wilson wrote:

Greetings,

In my studies I have come across octal permision mode with the find command. What on earth does it do, mean, refer to ?

The section is as follows find -perm mode : List file with the octal permission mode

I can find a decent understandable answer in the man pages or google.

This page has some information about octal permission mode: http://cfa-www.harvard.edu/cf/user_meetings/unix_groups/changing.html HL

It says that because the file permissions are specified using a number represented in octal - base 8. There are three bits for each of the four permission groups, each of which can be on or off - AKA 1 or 0. Three positions with 2 possiblities each gives 2^3, or 8. Hence, octal is the most convenient way to group the 4 sets of three binary digits. octal 0755 = binary 000111101101 = "ls output" ---rwxr-xr-x. It could just as easily be hexadecimal (1ED) or decimal (493), but the base-8 system is a lot handier for human use. If you've ever done a "chmod 0755 ~/public_html" then you've seen octal permission modes - the 0755 in there. Like everyone else said, "man chmod" th figure out exactly what each bit means. --Danny, noting that "ibase" and "obase" are real handy for checking your base conversions with bc... :)
