Top Forums UNIX for Dummies Questions & Answers How to move files based on filetype and time created? Post 302530189 by LuckyTommy on Monday 13th of June 2011 08:04:56 AM

Skrynesaver, thanks for the response.

Do you mind helping me decipher this code for a moment:

Code:
for i in $(file * |grep JPEG| cut -d\: -f1);do 
export i; ctime=$(perl -e ' @details = stat $ENV{i};print $details[10]'; if [ $ctime -gt 1306710000 -a $ctime <1307055600 ]
mv $i newFolder;
fi
done

I added indents to make it more readable.

Code:
for i in $(file * |grep JPEG| cut -d\: -f1);do

For each filename i in ( grep JPEG ) // What does "cut -d\: -f1" do?

Code:
export i;

Load the filename into variable i?

Code:
ctime=$(perl -e ' @details = stat $ENV{i};print $details[10]';

Extract the file attributes, parsing for creation time and load into variable ctime?

Code:
if [ $ctime -gt 1306710000 -a $ctime <1307055600 ]

If that creation time is > May 30 && < June 2nd

Code:
mv $i newFolder;

Move the file

Is that right?

Time::localtime(3pm)					 Perl Programmers Reference Guide				      Time::localtime(3pm)

NAME
Time::localtime - by-name interface to Perl's built-in localtime() function SYNOPSIS
use Time::localtime; printf "Year is %d ", localtime->year() + 1900; $now = ctime(); use Time::localtime; use File::stat; $date_string = ctime(stat($file)->mtime); DESCRIPTION
This module's default exports override the core localtime() function, replacing it with a version that returns "Time::tm" objects. This object has methods that return the similarly named structure field name from the C's tm structure from time.h; namely sec, min, hour, mday, mon, year, wday, yday, and isdst. You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your core functions.) Access these fields as variables named with a preceding "tm_" in front their method names. Thus, "$tm_obj->mday()" corresponds to $tm_mday if you import the fields. The ctime() function provides a way of getting at the scalar sense of the original CORE::localtime() function. To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package. NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this. AUTHOR
