Check whether file exists in directory
Hi guys,
I am beginner trying to learn unix. So any help is welcomed.
My requirement is to check whether is a file exists in a particular directory or not.
The directory path and filename are taken dynamically with user interaction. So the program should continue only if the $filename exists in $directory
Regards,
Maris Markur

lwp-download5.18
LWP-DOWNLOAD(1) User Contributed Perl Documentation LWP-DOWNLOAD(1)
NAME
lwp-download - Fetch large files from the web
SYNOPSIS
lwp-download [-a] [-s] <url> [<local path>]
DESCRIPTION
The lwp-download program will save the file at url to a local file.
If local path is not specified, then the current directory is assumed.
If local path is a directory, then the last segment of the path of the url is appended to form a local filename. If the url path ends with
slash the name "index" is used. With the -s option pick up the last segment of the filename from server provided sources like the Content-
Disposition header or any redirect URLs. A file extension to match the server reported Content-Type might also be appended. If a file
with the produced filename already exists, then lwp-download will prompt before it overwrites and will fail if its standard input is not a
terminal. This form of invocation will also fail is no acceptable filename can be derived from the sources mentioned above.
If local path is not a directory, then it is simply used as the path to save into. If the file already exists it's overwritten.
The lwp-download program is implemented using the libwww-perl library. It is better suited to down load big files than the lwp-request
program because it does not store the file in memory. Another benefit is that it will keep you updated about its progress and that you
don't have much options to worry about.
Use the "-a" option to save the file in text (ascii) mode. Might make a difference on dosish systems.
EXAMPLE
Fetch the newest and greatest perl version:
$ lwp-download http://www.perl.com/CPAN/src/latest.tar.gz
Saving to 'latest.tar.gz'...
