Capital Letters in File and Directory Permission Bits - Linux
This is a discussion on Capital Letters in File and Directory Permission Bits - Linux ; Sometimes, if I issue the command:
chmod +t mydir
or
chmod g+s mydir
The permission bit on the directory appears as a capital letter, instead of a
lower case letter.
For example:
drwxrwx--T 1 mark sticky 1024 Jan 1 1990 ...

Capital Letters in File and Directory Permission Bits
Sometimes, if I issue the command:
chmod +t mydir
or
chmod g+s mydir
The permission bit on the directory appears as a capital letter, instead of a
lower case letter.
For example:
drwxrwx--T 1 mark sticky 1024 Jan 1 1990 mydir
Why is there a capital T instead of a lower case one ?
The same happens with the sgid bit, I sometimes get a capital S.
drwxr-S--x 1 mark sticky 1024 Jan 1 1990 mydir
What is happing, and what do the capitals in the permission bits mean ?
Thanks in advance to anyone who can help.
Mark.

From:
info coreutils ls
The permissions listed are similar to symbolic mode specifications
(*note Symbolic Modes:
. But `ls' combines multiple bits into the
third character of each set of permissions as follows:
`s'
If the setuid or setgid bit and the corresponding executable
bit are both set.
`S'
If the setuid or setgid bit is set but the corresponding
executable bit is not set.
`t'
If the sticky bit and the other-executable bit are both set.
`T'
If the sticky bit is set but the other-executable bit is not
set.
`x'
If the executable bit is set and none of the above apply.
`-'
Otherwise.
