Full Discussion: Checking whether the file exists under a directory and doing a diff

In each dir do an "ls -1" to give you a single column of files. Output each to a new file. Then use comm to find the common and distinct files in each.

Code:
dev$ ls -1 >/tmp/dev.ls
dev$ cd ../uat
uat$ ls -1 >/tmp/uat.ls ;
cd /tmp
tmp$ comm dev.ls uat.ls

The man page on comm will tell you how to interpret the output and how to run it to get the results you want.

CPANPLUS::Shell(3)					User Contributed Perl Documentation					CPANPLUS::Shell(3)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
