Do you know about the obscure Linux command ‘seq’????? It is actually quite cool. seq ‘prints’ (sends to standard output) a sequence of numbers. By itself it does nothing, but with a few parameters it functions nicely.greg@workstation:~$ seq 10greg@workstation:~$ seq 3 9greg@workstation:~$ seq 10 10 110 But why would you want to do this? To sequentially number files that don’t exist yet using touch, for example!seq has c-like format capabilities. For those of you who don’t know c, this means that seq understands certain wildcard like tokens that are used to format stuff. Let’s say we want a sequence of files called “harvey” numbered from 01 to 10. The format for that would be %02g which can be put in the middle of a double-quoted string. So the string “harvey%02g” is a template. The command:seq -f "harvey%02g" 10will produce a sequence of ten strings each starting with harvey and ending with a number: To make these words into empty files, you use the “touch” comand. “touch” followed by a legal filename will update the timestamp of the file referred to. But, if there is no file of that name, touch creates it! So the string of made-up filenames is fed to touch as follows:touch $(seq -f "harvey%02g" 10)This one-liner will get you ten harveys! Oh, the -f flag in seq tells seq to use the formatting codes.
