The next nine characters are in three groups of three; they describe the permissions on the file.
The first group of three describes owner permissions; the second describes group permissions;
the third describes other (or world) permissions. Characters that may appear are:
r Permission to read file
w Permission to write on file
x Permission to execute file
The following characters only appear in the execute permission (x) position of the output.
S Same as s except execute is turned off
s If in owner permissions section, setuid bit is on;
if in group permissions section, setgid bit is on
T Same as t except execute bit is turned off
t Save text bit is on
You can set some permissions with the chmod(1) command.
After the permissions comes the number of links to the file.
Next comes the name of the owner of the file or directory.
Then comes the name of the group that owns the file or directory.
Following this is the size of the file, expressed in bytes.
After this comes a date and time. For a file, this is the time that the file was last changed; for a
directory, it is the time that the directory was created. The –c and –u options can change
which time value is used.
The last item on the line is the name of the file or directory.
ENVIRONMENT VARIABLES
ls uses the following environment variables:
COLUMNS
contains the terminal width in columns. ls uses this value to determine the number
of output columns to write using the –C option.
TZ
contains the time zone to be used when displaying date and time strings.
