Big pattern file matching within another pattern file in awk or shell
Hi
I need to do a patten match between files .
I am new to shell scripting and have come up with this so far. It take 50 seconds to process files of 2mb size . I need to tune this code as file size will be around 50mb and need to save time.
Main issue is that I need to search the pattern from Keys in one file(File1) and then that file becomes the pattern for another two files (File2 and File3).
Is there any other way to do it?
File content looks like below.
**File1**
**File2**
**File3**
**Keys**
**Sample output**
** shell script code so far**

Hi All,
I'm new to perl,
My requirement is to check if particular file exists.
e.g. filename.txt, filename1.txt, filename2.txt etc
I tried the below code:-
my $var1 = "filename.txt"
if ( -e ($var1 = ~ /file\w/))
{
print "File found \n";
}
else
{ print "File not found \n";
}

Hi Gurus,
I have a file like below.. I have to match each with predefined pattern. If matches then have to write the entire record to a separate file. If not make the value as NULL and write the entire record into another file.
