both of these read operations work on the same stdin. you need to assign to a different fd and use that for one of them. the easiest way to do this is to ditch the useless use of cat (uuoc award).
Now we redirect passwd_sample into fd 9 for the entire while block, yet only the first read operation operates on fd 9. in this way, we'll keep our position in the file with each iteration and read line-by-line but not interfere with the read that wants input from the terminal.
if you're using bash, you can use read -s -N 1 for grabbing a single key. otherwise you'll need to press enter rather than "any" key.

I have written a script to read the file line by line.
It is reading and printing the lines.
But it is coming out of loop before reading last line.
So I am not able to print last line.

I need some help. I would like to read in a text file.
Take a variable such as ROW-D-01, compare it to what's in one line in the text file such as PROD/VM/ROW-D-01 and only input PROD/VM into a variable without the /ROW-D-01.
Is this possible? any help is appreciated. (2 Replies)

io::all::http
IO::All::HTTP(3pm) User Contributed Perl Documentation IO::All::HTTP(3pm)NAME
IO::All::LWP - Extends IO::All to HTTP URLs
SYNOPSIS
use IO::All;
$content < io('http://example.org'); # GET webpage into scalar
io('http://example.org') > io('index.html'); # GET to file
"hello
" > io('http://example.org/index.html'); # PUT webpage
# two ways of getting a page with a password:
$content < io('http://me:secret@example.org');
$content < io('http://example.org')->user('me')->password('secret');
DESCRIPTION
This module extends IO::All for dealing with HTTP URLs. Note that you don't need to use it explicitly, as it is autoloaded by IO::All
whenever it sees something that looks like an HTTP URL.
The SYNOPSIS shows some simple typical examples, but there are many other interesting combinations with other IO::All features! For
example, you can get an HTTP URL and write the content to a socket, or to an FTP URL, of to a DBM file.
METHODS
This is a subclass of IO::All::LWP. The only new method is "http", which can be used to create a blank IO::All::HTTP object; or it can also
take an HTTP URL as a parameter. Note that in most cases it is simpler just to call io('http://example.com'), which calls the "http" method
automatically.
OPERATOR OVERLOADING
The same operators from IO::All may be used. < GETs an HTTP URL; > PUTs to an HTTP URL.
SEE ALSO
IO::All, IO::All::LWP, LWP.
