Just a small observation on the side: "-1" is unnecessary in this case, because ls will format its output in only one (instead of several) columns already if it notices that the output is not going to a terminal. See the following transcript:
I executed the following command in the korn shell:
$ variable1="qwerty" ls | sort
and the shell executed the 'ls | sort' command.
I would have expected an error message from the shell, but instead of that the shell ran the 'ls | sort' command and didn't realize the variable assignement. ... (1 Reply)

chgrp
CHGRP(1) User Commands CHGRP(1)NAME
chgrp - change group ownership
SYNOPSIS
chgrp [OPTION]... GROUP FILE...
chgrp [OPTION]... --reference=RFILE FILE...
DESCRIPTION
Change the group of each FILE to GROUP. With --reference, change the group of each FILE to that of RFILE.
-c, --changes
like verbose but report only when a change is made
-f, --silent, --quiet
suppress most error messages
-v, --verbose
output a diagnostic for every file processed
--dereference
affect the referent of each symbolic link (this is the default), rather than the symbolic link itself
-h, --no-dereference
affect symbolic links instead of any referenced file (useful only on systems that can change the ownership of a symlink)
--no-preserve-root
do not treat '/' specially (the default)
--preserve-root
fail to operate recursively on '/'
--reference=RFILE
use RFILE's group rather than specifying a GROUP value
-R, --recursive
operate on files and directories recursively
The following options modify how a hierarchy is traversed when the -R option is also specified. If more than one is specified, only the
final one takes effect.
-H if a command line argument is a symbolic link to a directory, traverse it
-L traverse every symbolic link to a directory encountered
-P do not traverse any symbolic links (default)
--help display this help and exit
--version
output version information and exit
EXAMPLES
chgrp staff /u
Change the group of /u to "staff".
chgrp -hR staff /u
Change the group of /u and subfiles to "staff".
