Working with files that are named with a timestamp
So I have a script that runs an ls on a given directory and looks for files with a timestamp that has the current hour in it and then does work with the files that it discovers
This is then run as a cron at 58 after the hour. This has obvious implications if the user manages to generate data between hh:58:01 and HH:00:00. it was a small risk but a risk nonetheless. It only took them two weeks. So now I need to figure out how to search for $DATE -1 hour and run the cron based on that and it has me stumped...
I've looked at several of the previous posts and can't seem to find any that pertain to my problem, I'd appreciate some help if possible.
I have a directory with numerous logs of various names all named by heading and date ie.
dog.20050529.log
dog.20050530.log

Hi Everyone!
Looking for some help with a script that will take all files in any given root folder (which are not already in a folder) and put them into separate folders with the name of each given file.
Any ideas?

I need to be able to identify files with file timestamps greater than a given timestamp.
I am using the following solution, although it appears to compare files at the "seconds" granularity and I need it at the milliseconds. When I tested my solution, it missed files that had timestamps... (3 Replies)

My question is, is there a way to use the join command listing the file... (4 Replies)

cron
CRON(8) System Manager's Manual CRON(8)NAME
cron - clock daemon
SYNOPSIS
auth/cron [-c]
DESCRIPTION
Cron executes commands at specified dates and times according to instructions in the files /cron/user/cron. It runs only on an authentica-
tion server. Option -c causes cron to create /cron/user and /cron/user/cron for the current user; it can be run from any Plan 9 machine.
Blank lines and lines beginning with # in these files are ignored. Entries are lines with fields
minute hour day month weekday host command
Command is a string, which may contain spaces, that is passed to an rc(1) running on host for execution. The first five fields are integer
patterns for
minute 0-59
hour 0-23
day of month 1-31
month of year 1-12
day of week 0-6; 0=Sunday
The syntax for these patterns is
time : '*'
| range
range : number
| number '-' number
| range ',' range
Each number must be in the appropriate range. Hyphens specify inclusive ranges of valid times; commas specify lists of valid time ranges.
To run the job, cron calls host and authenticates remote execution, equivalent to running rx host command (see con(1)). The user's profile
is run with $service set to rx.
Cron is not a reliable service. It skips commands if it cannot reach host within two minutes, or if the cron daemon is not running at the
appropriate time.
EXAMPLES
Here is the job that mails system news.
% cat /cron/upas/cron
# send system news
15 8-17, 21 *** helix /mail/lib/mailnews
