Question LINE_MAX (limits)
Perderabo,
Thanks for the reply. I have obviously missed the point somewhere. The LINE_MAX setting here is 2048 chars. How does this figure relate to the 12,000 chars (plus cr's, linefeeds) that appears to be the restriction.
Below are some positive and negative examples. The closest wc value I have achieved so far is 11,810 (without a failure) and I know it fails when it hits 12,044.
Does your reply still stand, or have I missed something.
Unfortunately, source .c/.h filenames being what they are, can only be picked up by using the filename extension. Developers tend not select alphabetically ordered filenames, otherwise I would use a*.c etc.

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
