This is a silly script but you would be surprised how many times a day I have to do this and no matter how many times I type the command, I always get it wrong (or more than likely I forget to escape something). Its also interesting to note that the scripts I find silly are usually the ones that are the most popular on this site….so here it is.
Basically, if you copy and paste this script into a file and run it, it will give you the exact date and time in the sed command to run to search all lines in a log file from the previous hour to now and save it to another file.
