Data Broken Pipe

Hi
I tried to open the man page of sh and piped to `pg`. Normally while reading a file page by page using `pg`, if we wanna quit at the middle of file, we give "q" near the colon mode.

Ex1: $cat file1 | pg
hi
how
r
u
:
(page1) now press "return key", it will go to next page
yes
i
am
fine
: q
(I wanna quit here and I gave q and its quit from the process normally)
$


The above mentioned condition is normal

My case is:

$ man sh | pg
User Commands sh(1)



NAME
sh, jsh - standard and job control shell and command inter-
preter

SYNOPSIS
/usr/bin/sh [-acefhiknprstuvx] [argument...]

--------- goes on

: q
(now if i give q here, its showing error "BROKEN PIPE")

why in normal case mentioned in example 1 its not happening, while in man sh|pg its happening (broken pipe)?

Please help me on this with clear explanation?

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
