So I have a HUGE file that I need to parse out. Each file will be around 16meg, and will be a text file.

I want to remove the first 76 characters from each line of the file. If the legnth of the line is less than 67 characters then it should be discarded.

I then want to count the number of occurances of the character '+' that are left in the file.

Because of the size of the file - what is the best/easiest language to do this in? Could it be done using some simple unix scripting, or would it be better to create a C++ or java program to do this?

I'd definitely say that a shell script could do this.

I'm not a script guy, so i'll defer to others on this, but the algorithm would seem simple enough.

perl should do it, no sweat. i've parsed files a lot larger than 16 meg in no time.

just read the file one line at a time and you should have no problems
