Comparing to specific line in file bash script

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)

In those files, there are only numbers. So each line is just a number witch should be present on both file.

Count character in one line 1 year 20 weeks ago

Please check the attachment for the example.

I would like to write a script that takes something like this: Line 1 Line 2 Line 3 Line 4 [Blank line] Line 6 Line 7 Line 8 Line 9 [Blank line] etc....

And makes it to look like this: Line 1|Line 2|Line 3|Line 4|[Blank line, if it's easier] Line 6|Line 7|Line 8|Line 9|[Blank line, if it's easier] etc.

I would think it would be fairly easy to use two loops, one for the the 5-li

Hello!

I'm currently trying to organize data for some bio research, but I'm not sure how to compare a value to values in a file. So what I have are 2 arrays, one array contains NM numbers and can be referenced as NM[#]. The other array has symbols, SYM[#].
