http://www.unix.com – Hi, I have a value stored in x and I need to compare it to the numbers in every other line of a file. The file contains alternating lines of numbers and letters: aaaa1111 AAAAAAAA bbbb2222 BBBBBBBB cccc3333 CCCCCCCC I need to compare x to the numbers in every other line without the first four characters of that line. So I want to compare x to 1111, then to 2222, then 3333. This is to be the condition in an if statement: if [ $x = (line 1 without first four characters) ] or if [ $x = (line 3 without first four characters) ] I know I would have to use something along the li (HowTos)
