How to do row comparison in shell script
Hi,
I need help on doing the below thing in shell script.
I have a file with millions of rows called "abc.txt". i have another file with millions of rows called "xyz.txt".
I would like to do the below operation.
Open the abc.txt, read the first line, do some operations on the column values and hold it in temp variable. Open the the xyz.txt and read the first line and do some operations on the column values and hold it in temp variables.
Write this temp values to the output file.
The major hiccups in this is i have to compare the first row of abc.txt with the first row of xyz.txt and second row to the second row and so on.
How can i do the comparison of first line with first line and second line with second line and so on ?
