Hi,
Currently I'm moving the files based on date like below.
"mv *20150901* backup_folder" - Limitation: can move only 1 day files to backup folder.
I want to move the files of different dates like 20150901,02, 03, 04.....
Is there any single command to do it.
Thanks in advance!! (2 Replies)

STRTOTIME(3) 1 STRTOTIME(3)
strtotime - Parse about any English textual datetime description into a Unix timestamp
SYNOPSIS
int strtotime (string $time, [int $now = time()])
DESCRIPTION
The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the
number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in $now, or the current time if $now is not supplied.
Each parameter of this function uses the default time zone unless a time zone is specified in that parameter. Be careful not to use dif-
ferent time zones in each parameter unless that is intended. See date_default_timezone_get(3) on the various ways to define the default
time zone.
PARAMETERS
o $time
-A date/time string. Valid formats are explained in Date and Time Formats.
o $now
- The timestamp which is used as a base for the calculation of relative dates.
RETURN VALUES
Returns a timestamp on success, FALSE otherwise. Previous to PHP 5.1.0, this function would return -1 on failure.
ERRORS
/EXCEPTIONS
Every call to a date/time function will generate a E_NOTICE if the time zone is not valid, and/or a E_STRICT or E_WARNING message if using
the system settings or the $TZ environment variable. See also date_default_timezone_set(3)
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.3.0 | |
| | |
| | Prior to PHP 5.3.0, relative time formats sup- |
| | plied to the $time argument of strtotime(3) such |
| | as this week, previous week, last week, and next |
| | week were interpreted to mean a 7 day period rel- |
| | ative to the current date/time, rather than a |
| | week period of Monday through Sunday. |
| | |
| 5.3.0 | |
| | |
| | Prior to PHP 5.3.0, 24:00 was not a valid format |
| | and strtotime(3) returned FALSE. |
| | |
| 5.2.7 | |
| | |
| | In PHP 5 prior to 5.2.7, requesting a given |
| | occurrence of a given weekday in a month where |
| | that weekday was the first day of the month would |
| | incorrectly add one week to the returned time- |
| | stamp. This has been corrected in 5.2.7 and later |
| | versions. |
| | |
| 5.1.0 | |
| | |
| | Now returns FALSE on failure, instead of -1. |
| | |
| 5.1.0 | |
| | |
| | Now issues the E_STRICT and E_NOTICE time zone |
| | errors. |
| | |
| 5.0.2 | |
| | |
| | In PHP 5 up to 5.0.2, "now" and other relative |
| | times are wrongly computed from today's midnight. |
| | This differs from other versions where it is cor- |
| | rectly computed from current time. |
| | |
| 5.0.0 | |
| | |
| | Microseconds began to be allowed, but they are |
| | ignored. |

EXAMPLES
Example #1
A strtotime(3) example
<?php
echo strtotime("now"), "
";
echo strtotime("10 September 2000"), "
";
echo strtotime("+1 day"), "
";
echo strtotime("+1 week"), "
";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "
";
echo strtotime("next Thursday"), "
";
echo strtotime("last Monday"), "
";
?>
Example #2
Checking for failure
<?php
$str = 'Not Good';
// previous to PHP 5.1.0 you would compare with -1, instead of false
if (($timestamp = strtotime($str)) === false) {
echo "The string ($str) is bogus";
} else {
echo "$str == " . date('l dS of F Y h:i:s A', $timestamp);
}
?>
NOTES
Note
If the number of the year is specified in a two digit format, the values between 00-69 are mapped to 2000-2069 and 70-99 to
1970-1999. See the notes below for possible differences on 32bit systems (possible dates might end on 2038-01-19 03:14:07).
Note
The valid range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 UTC to Tue, 19 Jan 2038 03:14:07 UTC. (These are the
dates that correspond to the minimum and maximum values for a 32-bit signed integer.)
Prior to PHP 5.1.0, not all platforms support negative timestamps, therefore your date range may be limited to no earlier than the
Unix epoch. This means that e.g. dates prior to Jan 1, 1970 will not work on Windows, some Linux distributions, and a few other
operating systems.
For 64-bit versions of PHP, the valid range of a timestamp is effectively infinite, as 64 bits can represent approximately 293 bil-
lion years in either direction.
Note
Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator
is a slash ( /), then the American m/d/y is assumed; whereas if the separator is a dash ( -) or a dot ( .), then the European d-m-y
format is assumed.
To avoid potential ambiguity, it's best to use ISO 8601 ( YYYY-MM-DD) dates or DateTime::createFromFormat when possible.
Note
Using this function for mathematical operations is not advisable. It is better to use DateTime::add and DateTime::sub in PHP 5.3
and later, or DateTime::modify in PHP 5.2.
