my initial purpose is wanted to pipe the files to a perl program.
see, say my perl program is getfile.pl (taking file names as argumemnts)
if i use:
> getfile.pl f1 f2 dir1 dir2
to execute the perl file, it's working.
However, if i use:
> ls | getfile.pl OR >find * | getfile.pl
it's not working. It wouldn't recoglise the input argument (@ARGV is empty)
also
>getfile.pl < f1 f2 dir1 dir2
it only recognise f2, dir1, dir2. The first argument f1 is missing. (ie. @ARGV only contains f2, dir1 and dir2)
sometimes I ftp files from an Unix environment from the command prompt of my win2000 pc and I get a "broken pipe" message. sometimes I'll get nothing but sometimes I'll get part of the file.
Whats this "broken pipe" about?? (3 Replies)
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

I know what causes 'broken pipe' errors, but I can't understand why I can get it (only occasionally) with my example:

Basically I'm searching the ps output looking for the process I'm interested in and excluding the process that is grepping for the... (2 Replies)

io::pipe
IO::Pipe(3pm) Perl Programmers Reference Guide IO::Pipe(3pm)NAME
IO::Pipe - supply object methods for pipes
SYNOPSIS
use IO::Pipe;
$pipe = new IO::Pipe;
if($pid = fork()) { # Parent
$pipe->reader();
while(<$pipe>) {
...
}
}
elsif(defined $pid) { # Child
$pipe->writer();
print $pipe ...
}
or
$pipe = new IO::Pipe;
$pipe->reader(qw(ls -l));
while(<$pipe>) {
...
}
DESCRIPTION
"IO::Pipe" provides an interface to creating pipes between processes.
CONSTRUCTOR
new ( [READER, WRITER] )
Creates an "IO::Pipe", which is a reference to a newly created symbol (see the "Symbol" package). "IO::Pipe::new" optionally takes two
arguments, which should be objects blessed into "IO::Handle", or a subclass thereof. These two objects will be used for the system call
to "pipe". If no arguments are given then method "handles" is called on the new "IO::Pipe" object.
These two handles are held in the array part of the GLOB until either "reader" or "writer" is called.
METHODS
reader ([ARGS])
The object is re-blessed into a sub-class of "IO::Handle", and becomes a handle at the reading end of the pipe. If "ARGS" are given
then "fork" is called and "ARGS" are passed to exec.
writer ([ARGS])
The object is re-blessed into a sub-class of "IO::Handle", and becomes a handle at the writing end of the pipe. If "ARGS" are given
then "fork" is called and "ARGS" are passed to exec.
handles ()
This method is called during construction by "IO::Pipe::new" on the newly created "IO::Pipe" object. It returns an array of two objects
blessed into "IO::Pipe::End", or a subclass thereof.
