Hi I have two similar files (both with 3 columns). I'd like to check if these two files contains the same elements (but listed in a different orders). First of all I'd like to compare only the 1st columns
file1.txt
"aba" 0 0
"abc" 0 1
"abd" 1 1
"xxx" 0 0
file2.txt
"xyz" 0 0
"aba" 0 0
"xxx" 0 0
"abc" 1 1
How can I do it using awk? I tried to have a look around but I've found only complicate examples. What if I want to include also the other two columns on the comparison? The output should give me the number of matching elements.
