How to count many lines have the same number in two columns?
I need to compare the numbers in two columns and count how many lines have the same value in both columns. For example:
17 19
17 17
17 18
19 19
25 22
34 34
Expected output:
3
I can't sort them because each line is a specific gene and I can't use awk because technically we haven't seen it in class yet. Is there any way to do this with grep?

One way would be to use grep with its Extended Regular Expressions mode, to match the value in column 1 and print all those lines whose second column is also the same. The first part ([^ ]+) captures the value in first column, and 1 means those lines whose value captured in the first column is also the same as second. The -c is for printing those lines returned.
grep -cE '([^ ]+) 1' file
