Hi All,
How can the head command be used to extract only a particular line.
By default head -n filename displays the first n lines. I want only the nth line.
I couldn't get it from forum search.

ZMORE(1) General Commands Manual ZMORE(1)
NAME
zmore - file perusal filter for crt viewing of compressed text
SYNOPSIS
zmore [ name ... ]
DESCRIPTION
Zmore is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy terminal. zmore works
on files compressed with compress, pack or gzip, and also on uncompressed files. If a file does not exist, zmore looks for a file of the
same name with the addition of a .gz, .z or .Z suffix.
Zmore normally pauses after each screenful, printing --More-- at the bottom of the screen. If the user then types a carriage return, one
more line is displayed. If the user hits a space, another screenful is displayed. Other possibilities are enumerated later.
Zmore looks in the file /etc/termcap to determine terminal characteristics, and to determine the default window size. On a terminal capa-
ble of displaying 24 lines, the default window size is 22 lines. To use a pager other than the default more, set environment variable
PAGER to the name of the desired program, such as less.
Other sequences which may be typed when zmore pauses, and their effects, are as follows (i is an optional integer argument, defaulting to
1) :
i<space>
display i more lines, (or another screenful if no argument is given)
^D display 11 more lines (a ``scroll''). If i is given, then the scroll size is set to i.
d same as ^D (control-D)
iz same as typing a space except that i, if present, becomes the new window size.
is skip i lines and print a screenful of lines
if skip i screenfuls and print a screenful of lines
q or Q Quit.
= Display the current line number.
i/expr search for the i-th occurrence of the regular expression expr. The user's erase and kill characters may be used to edit the regular
expression. Erasing back past the first column cancels the search command.
in search for the i-th occurrence of the last regular expression entered.
!command
invoke a shell with command. The character `!' in "command" is replaced with the previous shell command. The sequence "!" is
replaced by "!".
:q or :Q
Quit (same as q or Q).
. (dot) repeat the previous command.
The commands take effect immediately, i.e., it is not necessary to type a carriage return. Up to the time when the command character
itself is given, the user may hit the line kill character to cancel the numerical argument being formed. In addition, the user may hit the
erase character to redisplay the --More-- message.
At any time when output is being sent to the terminal, the user can hit the quit key (normally control-). Zmore will stop sending output,
and will display the usual --More-- prompt. The user may then enter one of the above commands in the normal manner. Unfortunately, some
output is lost when this is done, due to the fact that any characters waiting in the terminal's output queue are flushed when the quit sig-
nal occurs.
The terminal is set to noecho mode by this program so that the output can be continuous. What you type will thus not show on your termi-
nal, except for the / and ! commands.
If the standard output is not a teletype, then zmore acts just like zcat, except that a header is printed before each file if there is more
than one file.
