chmod -R u+w,go-w docs: Adds write permission to the directory docs and all its contents (i.e. Recursively) for owner, and removes write permission for group and others chmod ug=rw groupAgreements.txt: Sets read and write permissions for user and Group: chmod 664 global.txt: Sets read and write permissions for user and Group, and provides read ...
The following are some examples of symbolic notation: -rwxr-xr-x : a regular file whose user class has full permissions and whose group and others classes have only the read and execute permissions. crw-rw-r-- : a character special file whose user and group classes have the read and write permissions and whose others class has only the read ...
The setuid and setgid bits are normally represented as the values 4 for setuid and 2 for setgid in the high-order octal digit of the file mode. For example, 6711 has both the setuid and setgid bits (4 + 2 = 6) set, and also the file read/write/executable for the owner (7), and executable by the group (first 1) and others (second 1).
For example, to add the bit on the directory /usr/local/tmp, one would type chmod +t /usr/local/tmp. Or, to make sure that directory has standard tmp permissions, one could also type chmod 1777 /usr/local/tmp. To clear it, use chmod -t /usr/local/tmp or chmod 0777 /usr/local/tmp (the latter will also reset the tmp directory to standard ...

In Unix and Unix-like systems, including POSIX-conforming systems, each file has a 'mode' containing 9 bit flags controlling read, write and execute permission for each of the file's owner, group and all other users (see File-system permissions §Traditional Unix permissions for more details) plus the setuid and setgid bit flags and a 'sticky' bit flag.

Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
