Finding files modified within a specific time periodPosted: April 21, 2018
I had been working experimentally on a file a couple of days ago and forgot to change the name to something meaningful. I remembered roughly when I was working on it and would recognise the name and context when I saw it (probably). But the problem is how to you find the relevant files? Stackoverflow to the rescue (as always), with a bit of
find /home/dan/ -name *.xml -mtime -2 -ls |more
It’s all pretty self explanatory except the
-mtime -2: the utility, the start directory, any restrictions on the file name (you want to use this if you are searching a home directory: I have 10k+ files, it looked like before I added it, given all the cache files from the web browsers), the time period in days (-mtime), and a ls-style display. |more is a pipe that allows you to look at the output in segments if there is more than a screen’s worth.
-mtimeis the only funny bit: it searches back the number of days expressed by its value. If the value is positive, it searches bac roughly that number of days from the moment it is invoked (roughly in the sense of “about 48 hours ago” in this case); if the number is negative, it search back from now until that number of days (or in this case “from now back to about two days ago”).
If you need a timeframe less than a day, there is a switch for minutes as well.
