gawk has been my go-to text processing program for many years. I have written a number of multi-thousand line programs in it. I always use the lint option. Catches many of my errors. One of these had to read a 300,000,000 byte file into a single string so it could be searched. The file was in 32-byte lines. At first, I read each line in and appended it to the result string, but that took way to long since the result string was reallocated each time it was appended to. So I read in about 1000 of the 32-byte lines, appending them to a local string. This 32000-byte string was then appended to the result, so this only was done 10000 times. Worked fine.
