How do you get the last modification date of a file?
I'm trying to get the date output to be in the form yyyy-mm-dd (e.g. 2013-01-18)
When I run this on another file (by typing ./dateScript theFile.txt), I keep getting this message:
stat: illegal option -- c
What's wrong with my code here or how can I fix it?
What about the following instead? I was told that date -r does what I want, but I can't seem to get it to. Since I can't find much information on how to use the date command, I've put it off to the side unless someone else knows how I can get the last modified date from a file with the date command.
Any other simple suggestions to get the last modification date of a file so that I can append it to the end of said file would be great too. I've been trying to figure out some variation of this problem for a few hours now and at this point I have no new ideas and am completely stagnant, so any help is really appreciated.
Good morning,
I would like to find all files of a certain type and display their name as well as their modification date.

Hi
I'd like to know if is it possible to find files given a certain modification date (say, 01-05-2006, that's 1st of May 2006)
I can calculate the days backward:
find / -ctime 23
but I wish to search by exact modification day
Thanks (5 Replies)

I realize this is basic and probably obvious, but I'm pulling my hair out. I'm guessing this is just some flag on the file command or somesuch, but I can't find it. Help me get unstuck please?

Hi, I'm executing a script to check if a file has been modified on a shared folder.

EXAMPLES
Example #1
DateTime.__construct(3) example
Object oriented style
<?php
try {
$date = new DateTime('2000-01-01');
} catch (Exception $e) {
echo $e->getMessage();
exit(1);
}
echo $date->format('Y-m-d');
?>
Procedural style
<?php
$date = date_create('2000-01-01');
if (!$date) {
$e = date_get_last_errors();
foreach ($e['errors'] as $error) {
echo "$error
";
}
exit(1);
}
echo date_format($date, 'Y-m-d');
?>
The above examples will output:
2000-01-01
Example #2
Intricacies of DateTime.__construct(3)
<?php
// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "
";
// Specified date/time in the specified time zone.
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "
";
// Current date/time in your computer's time zone.
$date = new DateTime();
echo $date->format('Y-m-d H:i:sP') . "
";
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "
";
// Using a UNIX timestamp. Notice the result is in the UTC time zone.
$date = new DateTime('@946684800');
echo $date->format('Y-m-d H:i:sP') . "
";
// Non-existent values roll over.
$date = new DateTime('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "
";
?>
The above example will output something similar to:
2000-01-01 00:00:00-05:00
2000-01-01 00:00:00+12:00
2010-04-24 10:24:16-04:00
2010-04-25 02:24:16+12:00
2000-01-01 00:00:00+00:00
2000-03-01 00:00:00-05:00
