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:

Code:
# uname -srv
AIX 1 7

# for i in a b c d e ; do touch $i ; done

# ls -l
total 0
-rw-r--r--    1 bakunin     staff             0 Sep 26 17:27 a
-rw-r--r--    1 bakunin     staff             0 Sep 26 17:27 b
-rw-r--r--    1 bakunin     staff             0 Sep 26 17:27 c
-rw-r--r--    1 bakunin     staff             0 Sep 26 17:27 d
-rw-r--r--    1 bakunin     staff             0 Sep 26 17:27 e

# ls
a  b  c  d  e

# ls | cat -
a
b
c
d
e

I hope that helps.

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
