Problem passing directory as argument with awk
I'm trying to figure out what's getting passed as the argument when I try to pass a directory as an argument, and I'm getting incredibly strange behavior. For example, from the command line I'm typing:

Code:
nawk -f ./test.awk ~

test.awk contains the following:

Code:
{
  directory = $NF
  print directory;
}

And I get the following output:

.dtprofile
.slickedit
cqcc_cache
search.txt
Command.pm
xcleardiff

These are only a few of the files in my home directory. Other directories return nothing at all even though they have hundreds of files in them. How is this behavior explained? I can't make heads or tails of it.

on

on(1)								   User Commands							     on(1)

NAME

       on - execute a command on a remote system with the local environment

SYNOPSIS

       on [-i] [-d] [-n] host command [argument] ...

DESCRIPTION

       The on program is used to execute commands on another system, in an environment similar to that invoking the program. All environment vari-
       ables are passed and the current working directory is preserved. To preserve the working directory, the working file system must be  either
       already	mounted  on the host or be exported to it. Relative path names will only work if they are within the current file system. Absolute
       path names may cause problems.

       The standard input is connected to the standard input of the remote command. The standard output and the standard  error  from  the  remote
       command are sent to the corresponding files for the on command.

OPTIONS

       The following options are supported:

       -d	Debug mode. Prints out some messages as work is being done.

       -i	Interactive mode. Uses remote echoing and special character processing. This option is needed for programs that expect to be talk-
		ing to a terminal. All terminal modes and window size changes are propagated.

       -n	No Input. This option causes the remote program to get EOF when it reads from the standard input, instead of passing the  standard
		input  from  the  standard  input of the on program. For example, -n is necessary when running commands in the background with job
		control.

DIAGNOSTICS

       unknown host

	   Host name not found.

       cannot connect to server

	   Host down or not running the server.

       can't find

	   Problem finding the working directory.

       can't locate mount point

	   Problem finding current file system.

       RPC: Authentication error

	   The server requires DES authentication and you  do not have a secret key registered with keyserv. Perhaps you logged in without a pass-
	   word. Try to keylogin.  If that fails, try to set your publickey with chkey.

       on server: RPC: can't encode arguments

	   The 10240 byte limit for arguments to be encoded and passed from the sending to the receiving system has been exceeded.

       Other diagnostic messages may be passed back from the server.

BUGS

       When the working directory is remote mounted over NFS, a Control-Z hangs the window.

       Root cannot use on.
