I have a file in which text file in which data is in the format
Code:
123456,1234567890,400,QWERTY,112121
987654,2345678901,300,ABCDEF,987909

There are similar rows in the data file.

Now I have to write a code in which user shall enter the values in the first column or the 2nd column such as 123456 or 987654, 1234567890 or 2345678901.

So I will take this input from the user and find the text entered by the user and match it in the input data file.

If the text matches then I need to write the rest of the values in that row in a new file.

Hence what I need is,
1) How to perform search (I tried grep command but if I enter 123, it searches it and says "Item Present", though it is not.
2) I want to read the data in the file until I encounter a comma, this way I shall be able to write the rest of the values of the row into the output file.

I hope problem is clear.
Kindly help me.
