Perl - grep issue in filenames with wildcards
Hi
I have 2 directories t1 and t2 with some files in it. I have to see whether the files present in t1 is also there in t2 or not. Currently, both the directories contain the same files as shown below:

$ABC.TXT
def.txt

Now, when I run the below script, it tells def.txt is found, $ABC.TXT not found. Since the filename itself contains wildcard, grep seems to be having some issue:


Code:
#!/usr/bin/perl
 
 
my @src=`ls /home/t1/`;
my @dest=`ls /home/t2/`;
 
foreach my $file (@src){
   @match=grep(/$file/, @dest);
   if (@match==0){
      print "Found $file";
   }else{
      print "Not found $file";
   }
}

Output:
Code:
Found def.txt
Not found $ABC.TXT

Please advice. I have put 2 files for samples. I also have some files like $$ABC.TXT, $$$ABC.TXT.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
