Old 03-19-2019
Despite nezabudka's and MadeInGermany's comments being correct they don't explain the error message. It comes from the shell interpreting the < as the redirection operator for stdin, and it doesn't find the file named the $error_limit's value. Escaping it would have helped circumvent that error, but had immediately stumbled over the next one: <= is not an accepted operator (in bashat least - you didn't mention the shell you use), use ! ... \> in lieu. Be aware that either of these compare values lexicographically using the current locale, so 145 would be considered less than 87, for instance. That's where nezabudka's proposals to use integer / numerical operators (like -le) come into play.

nwauth

NWAUTH(1)							      nwauth								 NWAUTH(1)

NAME

       nwauth - Verify username/password

SYNOPSIS

       nwauth [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -D ]

DESCRIPTION

       nwauth  does  nothing  but logging into a NetWare server. If the login was successful, an error code of 0 is returned. If the login was not
       successful, an error code of 1 is returned. It was designed for use by other programs who want authenticate users via a NetWare server.

       If there is no -P or -n option specified on command line, nwauth always expects a password on stdin. If the stdin is a tty, then  the  user
       is prompted for a password. Otherwise nwauth simply reads stdin for a password.

       nwauth  looks  up the file $HOME/.nwclient to find a file server and a user name if they are not specified on command line. See nwclient(5)
       for more information. Please note that the access permissions of .nwclient MUST be 600, for security reasons.

OPTIONS

       -h
	  -h is used to print a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user name
	  If the user name your NetWare administrator gave to you differs from your unix user-id, you should use -U to tell the server about  your
	  NetWare user name.

       -D
	  nwauth  says	that  your password is correct if you have existing connection to server with name user name. This is handy for some shell
	  scripts, but it is unacceptable for authorization modules, such as PAM, PHP or Apache. It was pointed to me that this behavior  was  not
	  well	known, and there exist at least one PAM module which does not know that (this module is not part of ncpfs; you should use PAM mod-
	  ule which comes with ncpfs instead anyway).
