Error Capturing Particular Data

Hi everyone!

Can any one help me out regarding capturing relevant data from a file.

For e.g, if i want to capture the comment written after "Prompt:" for a particular date, like for this case what would be the command to capture the tag written after "Prompt:" for Date: 2009-03-20.

A brief intro is for your reference:

Actually i want to capture number of Prompt with their tags for one particular day using script, if any one can help me out in letting me know the command i can use that in my script later.

This script will run on daily basis and will capture the tags written after "Prompt:" for one particular date.

You can use sed to do that it will start looking at lines starting with "<beginingOfLine>=<anyNumberOfTimes>Date: <date>" until it reaches another line begining with =<anyNumberOfTimes>, then remove all the text up to and including the word "Prompt:"
Code:
sed -n -e '/^=*Date: 2009-03-18/,/^=*/s/^.* Prompt: //p' inputFile

Thanks ldapswandog,

Things started to workout, but the output is as follows by using your command;

Local network interface[172.17.215.10:13005] is opened. (i.e. the starting line for that date)

and if i change ur command to :

sed -e '/^=*Date: 2009-03-18/,/^=*/s/^.* Prompt: //p' inputFile

then the oputput is same as input file

please guide.

Try awk:
Code:
awk -F:\  'f && /Prompt/{print $2}/=$/{f=((/2009-03-20/)?1:0)}' log

Sorry about that you need to add an '=' sign to each of the wildcard searches so it consistently captures lines with 2 or more in a row.
Code:
sed -n -e '/^==*Date: 2009-03-18/,/^==*/s/^.* Prompt: //p' inputFile

# 6  
thnks a million for this

it really worked

also please help me from this prespective that

now by running the mentioned commnad the output is without time, how can i get the time.

Start the substitute at [DS1]
Code:
sed -n -e '/^==*Date: 2009-03-18/,/^==*/s/\[DS1\].* Prompt: / /p' inputFile
