Shell Programming and Scripting

Hi,

Can any one tell me how to copy an alertlog file from a particular time stamp using shell script?

Thanks

that's by copy command ( cp ) only, can you please be more specific in your questions if possible with some mock examples?

Also, please post what you have tried so far.

Hi

Actually, i need to copy an alert log file from a particular time stamp.
its like

Ex:

alertlog file
------------

xxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxx
Mon Dec 15 04:30:15 2008
xxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxx
Tue Dec 16 05:40:25 2008
xxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxx
-----------------------------------------------

then i want to copy the file from timestamp "Tue Dec 16 05:40:25 2008" into a new file.

i hav tried like this

====================================

d="Wed Dec 17 06:50:35 2008"
cp=0
cat alert_<SID>|while read line
do
if [ $line -eq $d ]
then
cp=1
fi
if [ $cp -eq 1 ]
then
echo $line|cat a.txt
fi
done
====================================

is there any mistake in this?

something like this

Code:

awk '{ if ( $0 ~ /Tue Dec/ ) { ok=1 } if ( ok ) { print } }' filename

to print lines starting from a patten match to till the end of the file.

Please correct me if I have misunderstood the problem.
