Hi, I have a long list of string (each string is in a line). I need to count the number of appearance for each string.
I currently use `sort` to sort the list and then use another program to do the count. The second program doing the count needs only a small amount of the memory as the input is sorted. But `sort` writes a lot of temp files like `sortjISjDY`, which are very large. Because I only need the count, ideally, I'd like these temp files only keep the count info and the original string once, but not the original string many times. Does anybody know any better way to make the sort and count run more efficiently? -- Regards, Peng
