I'm trying to write a script that checks the DTS of a file the compares it to the current time. If greater that 60 mins has gone by and the file has not been written to alert.
So far I have the time pulled from the file but I dont know how to compare the times against a 60 min difference.

I need to move files after midnight but attach the previous date to it.
Moving files before midnight no proproblem but how can I move files which are created on the 22nd for example but add a date stamp of previous day?
Date ='date +"Y%m%d"' gets today's date but how can I get yesterday's... (3 Replies)
Hi,
can any one tell me how to achieve this...I will input the path and file name and it should rename it to current date and time...
this is what I tried...
#! /usr/bin/sh
set -x

Dear Gurus,
I'm trying to move a number of files from one directory to another directory with a new date stamp. This is my script:
#! /bin/csh
Today_Date=`date +%Y%M%D`
mv /usr/TRS/data/TS* /usr/TRS/backup/TS*.${Today_Date}
when i run the script i'm getting the following errors:

Hi All,
Wondering if there is have a date added at the end of a test string. I have a hypothetical text file day one:
John
Paul
George
When the file day one is output, I'd like it to read something like this:
John 101406
Paul 101406
George 101406
Day two, when the same text file... (0 Replies)
Hi,
We are using RSYNC for syncing remote directories and working great. Our requirement is to have the destination files with date/time stamp of when they're copied on to the destination server, NOT the date/time stamps of source files/directories.
As RSYNC, by default, preserving the same... (4 Replies)
Hi,
Below is the content of the file how it looks:

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
