Shell Programming and Scripting

Hi,
I have following problem. I have a file with time stamps and some data describing what happened between time stamps. Something like this:

10:00
meeting with K
meeting with L
11:00
lunch
12:00
work with K
13:00

From this file I have to get a file with time stamps and lines between them only if K was mentioned. So in this example the resulted file will be:

10:00
meeting with K
meeting with L
11:00
12:00
work with K
13:00

Any help will be greatly appreciated.

If you only want lines beginning with the word meeting or with the time:

Code:

awk '/:/ || /^meeting/' file > new_file

Regards

Thank you!
but this solves the problem only partially. I need all lines in that time period even if only one line has the pattern.

Code:

cat file.txt | perl -n -e 'print if( /\d\d:\d\d/ || /^meeting/ || /\s+K/ )';

To select those blocks with "meeting" or "work":

Code:

awk '
/meeting/ || /work/ {f=1}
/:/ && f {print s; print; s=""; f=0; next}
/:/ {s=""}
{s=s? s "\n" $0: $0}
' file > new_file

Regards

In both cases I'm getting:
