Grep in multiple columns

Shell Programming and Scripting

Hi All,

One of my source file is having more than 100 columns. Now, I need to check the particular string in 75th,76th and 79th columns of the source file.

If I find the particular string in above mentioned columns, then I need to print the entire record with line number.

Kindly help me how to achieve this.

Ex:

String to check:
100,200,300

Source File:

75thcolumn,76th column,79th column
1,2,3
500,700,800
100,200,300
700,250,120

Expected Result:

3 100,200,300

Thanks

Suresh

Try :

awk -F, '$75==100 && $76==200 && $79==300{print NR, $0}' file
