Shell Programming and Scripting

I am facing a problem while storring the grep results into a variable. I need to count the occurence of the pattern \, in a file and store that in a variable. I have given the below command

p=`grep -c '\\,' filename`

But while echoing the variable, i am getting the total number of lines in the file instead of the count of lines having pattern \, . If i give grep directly i am getting the correct result. Please help

$grep -c '\\,' filename
1
$p=`grep -c '\\,' filename`
$echo $p
29

Code:

$ 
$ 
$ cat f2
Nothing on this line
this line has \, and \, and \, here
and finally \, and \,
but nothing here
$ 
$ 
$ grep '\\\,' f2
this line has \, and \, and \, here
and finally \, and \,
$ 
$ 
$ grep -c '\\\,' f2
2
$ 
$ x=$(grep -c '\\\,' f2)
$ 
$ echo $x
2
$ 
$ 

(A) Number of lines in file f2 that have the pattern "\," = 2.
(B) Number of occurrences of the pattern "\," in those 2 lines = 5.

I've assumed you want (A), although the following two statements in your post are contradictory:
