Top Forums Shell Programming and Scripting Compare file dates before copy Post 303021436 by Neo on Thursday 9th of August 2018 09:17:50 AM

If you convert to DMY format, will have have to write more code to instruct a computer to compare dates.

That's why UNIX time is so great.

You can easily compute with it.

On my backups, I use standard date and time format because I don't use the information to have a computer compare the dates / times.

So, I prefer human readable file names.

But if I was comparing the times using a computer, then I use UNIX time.

For example, when you logout of this forum, we set a cookie of your last login time, so when you login again, we know what posts you have not seen, based on time, etc.

This cookie stores the time in UNIX time.

NAME
finger - user information lookup program SYNOPSIS
finger [ options ] name ... DESCRIPTION
By default finger lists the login name, full name, terminal name and write status (as a `*' before the terminal name if write permission is denied), idle time, login time, and office location and phone number (if they are known) for each current UNIX user. (Idle time is minutes if it is a single integer, hours and minutes if a ':' is present, or days and hours if a 'd' is present.) A longer format also exists and is used by finger whenever a list of people's names is given. (Account names as well as first and last names of users are accepted.) This format is multi-line, and includes all the information described above as well as the user's home directory and login shell, any plan which the person has placed in the file .plan in their home directory, and the project on which they are working from the file .project also in the home directory. Finger may be used to lookup users on a remote machine. The format is to specify the user as ``user@host.'' If the user name is left off, the standard format listing is provided on the remote machine. Finger options include: -m Match arguments only on user name. -l Force long output format. -p Suppress printing of the .plan files -s Force short output format. FILES
/etc/utmp who file /etc/passwd for users names, offices, ... /usr/adm/lastlog last login times ~/.plan plans ~/.project projects SEE ALSO
chfn(1), w(1), who(1). AUTHOR
Earl T. Cohen BUGS
Only the first line of the .project file is printed. There is no way to pass arguments to the remote machine as finger uses an internet standard port. 4th Berkeley Distribution May 10, 1986 FINGER(1)
