I don't believe a not grep expression will solve your issue. Perhaps you want something like grep "^/dir_a/", this will print any line that begins with "/dir_a/"
I have already tried those conditions but no luck, so when i want to count files in dir_a it should only give me 2 files but not 3. Is there a better wat to get the accurate number.
Code:
cat file|grep dir_a|wc -l
       3
cat file|grep dir_b|wc -l
       1

Btw if it begins with dir_a also i will see 3 files in dir_a even though there are only 2 because when i have a list of files in one file with the full path, that is how you will get the number.

bzfgrep

BZGREP(1)						      General Commands Manual							 BZGREP(1)

NAME

       bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression

SYNOPSIS

       bzgrep [ grep_options ] [ -e ] pattern filename...
       bzegrep [ egrep_options ] [ -e ] pattern filename...
       bzfgrep [ fgrep_options ] [ -e ] pattern filename...

DESCRIPTION

       Bzgrep  is  used to invoke the grep on bzip2-compressed files. All 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  bzgrep  is  invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, bzgrep
       uses it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	bzgrep string files
	   for csh: (setenv GREP fgrep; bzgrep string files)
