Getting file timestamp in certain format
Hi all,

I'm a Unix newbie and I need to get file timestamp in the following format:
Code:
YYYYMMDD HH24:MM:SS

example:
Code:
20120713 18:49:30

For start I've tried the following code, but I don't know how to display the year and even format the date:
Code:
ls -l $filename | awk '{print $7 $6 $8}'

My environment is HP-UX so I need to get it using Korn shell.

Any help would be greatly appreciated.

Thanks & Regards,

Setya

How is your input date looking? I don't have your environment to test...

I'd actually just started up a wiki to try to add things that would help when I'm teaching that might be helpful to you.

Code:
date +%Ymd %H%M%S

Give 'man date' a look, will have some HP-UX specific options in it and might have a prefab close to what you're looking for.

Hi,

Thank you for your response.
As I understand 'date' is used to display current timestamp.
What I need is to display file timestamp with certain format.

Regards,

Setya

Code:
filemtime()
{
perl -e '      
      # @arr = stat("$ARGV[0]");
      ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = 
            localtime( (stat("$ARGV[0]") )[9]);
      printf("%4d %02d %02d %02d:%02d:%02d",
            $year+1900, $mon+1, $mday, $hour, $min, $sec);     
      '  $1
}

echo $(filemtime t.lis)

ls -l will not work because the date format changes for files older than 6 months.
perl or some other language like C is the only generally available choice.
