![]() ![]() In this simple tutorial, we’ll quickly look at the solution to this problem. In order to delete files older than X number of days, try using Unix find command. find command is more powerful than you can really imagine. It comes up with multiple options which when gets handy can help you cover a lot of functional requirements like moving files among directories, deleting old files, archiving files etc. Recently I came across one such requirement of deleting files older than X days from a directory in Unix server and I thought of sharing the solution with you. Replace x with the number of days before which the files have to be compressed. Unix find command is used to achieve the desired result.įind /path/to/the/directory/ -type f -name '*' -mtime 30 -exec rm \ : This is actually the execution command which calls for deletion of all the files filtered by all the above criteria. LastWrite (get-date).AddDays(-x) date(Get-Date). Rm stands to remove in Unix.Īlthough it is a very simple command, still I want you understand the usage of mtime in find command in a little more detail. ![]() The POSIX specification for find command states that : mtime n The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n. In the descriptions, wherever n is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a plus ( ‘ ’ ) or minus-sign ( ‘-‘ ) sign, as follows: n More than n. Important point to note in the above statement is that the fractional part is always ignored. ![]() So, when you specify -mtime 1, it looks for files older more than 1 day. Rather to explain it further, it simply says to match files modified two or more days ago. If you want to delete files older than 1 day, you can try using -mtime 0 or - mtime 1 or - mmin $((60*24)). ![]() Would suggest you to try playing with the combinations on your own to deepen the understanding. Still in case you have questions, please feel free to get in touch with me. ![]()
