data:
i have a file that contains chunks similar to the above.
i want to parse this file and skip over chunks that have entry time which is older than 60 days. Meaning, DO NOT output those chunks.
Please note, some of the chunks in the data file do not have "entry_time". so for those entries, i want this script to output the chunk and move on to the next chunk.
So in other words, i want to do the date subtraction only on chunks that have "entry_time".
this is the code i'm using:
how do i substract the entry time from the time now??? and also, is this script good enough to do what i need?
I want to calculate the date of next satureday of current date using shell script.
Suppose, today is 27-feb-08
I want to get the date of next satureday, which means 01-mar-08, in the formate '' YYMMDD ".
I do this in ksh..
Please tell me any type of command which help me out.

avisplit
avisplit(1) General Commands Manual avisplit(1)NAME
avisplit - split AVI-files into chunks of a maximum size
SYNOPSIS
avisplit [ -i file -o base [ -s size ] [ -H num ] [ -t s1-s2[,s3-s4,..] -c -m -b num -f commentfile ] ] [ -v ]
COPYRIGHT
avisplit is Copyright (C) by Thomas Oestreich.
DESCRIPTION
avisplit splits a single AVI-file into chunks of size size.
Each of the created chunks will be an independent file, i.e. it can be played without needing any other of the chunk.
OPTIONS -i file
Specify the filename of the file to split into chunks.
-o base
Specify the base of the output filename(s) avisplit will then split to base-%04d.avi
-s size
Use this option to specify the maximum size (in units of MB) of the chunks avisplit should create. 0 means dechunk, create as many
files as possible.
-H num Create only the first num chunks then exit.
-t s1-s2[,s3-s4,..]
Split the input file based on time/framecode (hh:mm:ss.ms)
-c Together with -t. Merge all segments into one AVI-File again instead generating seperate files.
-m Together with -t. Force split at upper bondary instead of lower border.
-b num Specify if avisplit should write an VBR mp3 header into the AVI file. Default is 1 because it does not hurt. num is either 1 or 0.
-f commentfile
Read AVI tombstone data for header comments from commentfile. See /docs/avi_comments.txt for a sample.
-v Print only version information and exit.
EXAMPLES
The command
avisplit -s 700 -i my_file.avi
will split the file my_file.avi into chunks which's maximum size will not exceed 700 MB, i.e. they will fit onto a CD, each. The created
chunks will be named my_file.avi-0000, my_file.avi-0001, etc.
avisplit -i my_file.avi -c -o out.avi -t 00:10:00-00:11:00,00:13:00-00:14:00
will grab Minutes 10 to 11 and 13 to 14 from my_file.avi and merge it into out.avi
BAD SYNCH
When you split a file with avisplit and the A/V sync for the first file is OK but the sync on all successive files is bad then have a look
at the output of tcprobe(1) (shortend).
| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
| 10 chunks, 1920000 bytes
You'll see the AVI file has only 10 Audio chunks but 250 video chunks. That means one audio chunk spans several video frames. avisplit can
not cut a chunk in half, it only handles complete chunks. If you do, say, avisplit -s 20, it is possible that the first file will have 6
audio chunks and the second one only 4 meaning there is too much audio in the first AVI file.
The solution is to remux the AVI file with
transcode -i in.avi -P1 -N 0x1 -y raw -o out.avi
(of course -N 0x1 is not correct for all AVI files). Now look at tcprobe again
| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
| 250 chunks, 1920000 bytes
The data in this file is exactly the same (its bit-identical) as it was in in.avi; the AVI file was just written in a different way, we do
now have 250 audio chunks which makes splitting much easier and more accurate for avisplit.
