i have to grep a series say 98782 from a group by series in a file ,plz tell me how can i grep the series.

Hi,

Could you give an example of what you want? The above description is not very clear.

Even better - show us what you have attempted, and why you need help.

grep "98782" <filename>

example
 

there is a file of mobile numbers having lacs of mobile number
i have to grep the count of a particular series say 9872 from that file
problem is that when i am using grep "9872" its works but it is searching the numbers like
9156239872
9198720002
As it find the series 9872 at last and middle.
I have to find only those number start with series "9872"
9872 may be at middle or end but i have to find numbers start with 9872.

Hi,

As ajeetsinghraina guessed correctly, you can use grep to do that.

grep "^9872" filename should do the trick.

The ^ tells grep to only look for entries that start with the search pattern.

Hope this helps.

grep ^9872 <filename>

Edit: druuna beat on this.
