First of all, we’ll go through the different timestamps of a file provided by Linux’s EXT file system. enables you to change the names, attributes, and timestamps of files in one go. These dates can be of any pattern like YYYY-MM-DDThh:mm:ss or dd/mm/yyyy hh.mm.ss. Overview In this tutorial, we’ll cover how we can check a file’s age and modification time in Linux. Perfect for any kind of file renaming including music and photo files. How do I get a file's timestamp in perl If you want to retrieve the time at which the file was last read, written, or had its meta-data (owner, etc) changed, you use the -M, -A, or -C filetest operations as documented in the perlfunc manpage. Sometimes there are dates in the file name like sample T11:10:10.csv or there could be a column in a file that has a date in it. I checked that the variables are working right with the commented out print statements, but when I run the program I get a message that says "Cannot rename file: Invalid argument at line 13." I'm not sure what I'm doing wrong here. In Perl generally, we have to read CSV (Comma Separated Values) files to extract the required data. Rename $oldfile, $newfile or die "Cannot rename file: $!" Opendir(DIR, $dirnam) or die "Cannot open directory: $!" I'm very new to perl, and I want to rename a group of files so that they are lowercase instead of uppercase (so from SBC005.wav -> sbc005.wav). These timestamps were discussed briefly when we talked about getting information about a file: the last access time, the last modification time, and the last.
