I'm new to FreeBSD but not new to Linux/UNIX so bear with me.
I tried using "nl" to number lines in standard out put and I got this:
102 scott@blue: /home/scott > ls -al | ln
usage: ln [-fhinsv] file1 file2
ln [-fhinsv] file ... directory
link file1 file2
My question is: what is the "nl" command under FreeBSD used for? I guess
"cat -n" would give the results I'm looking for but what happend to nl
(number lines)?
man nl gives me this (output cut for brevity):
curs_outopts(3X) curs_outopts(3X)
NAME
clearok, idlok, idcok immedok, leaveok, setscrreg,
wsetscrreg, scrollok, nl, nonl - curses output options
SYNOPSIS
#include <curses.h>
int clearok(WINDOW *win, bool bf);
int idlok(WINDOW *win, bool bf);
void idcok(WINDOW *win, bool bf);
void immedok(WINDOW *win, bool bf);
int leaveok(WINDOW *win, bool bf);
int setscrreg(int top, int bot);
int wsetscrreg(WINDOW *win, int top, int bot);
int scrollok(WINDOW *win, bool bf);
int nl(void);
int nonl(void);
DESCRIPTION
These routines set options that change the style of output
within curses. All options are initially FALSE, unless
otherwise stated. It is not necessary to turn these
options off before calling endwin
