I just put the logic in for printing out 30, based on user input of 39, work on the logic and you can get it to print 48 or whatever the next number is. Off course the script needs improvement in terms of error checking, checking if user did supply $1 etc., left as an exercise for OP . It will go up and down 100 numbers only, which can be tweaked.
I want to grep a range of numbers in a log file. My log file looks like this:

That is a combination of yr,month,date,hours,minutes,seconds.
I want to search in the log file events that happened between a particular time.

hi guys,
I want to do pattern matching with awk or sed but I don't know how. here's what I want:
I have a line number for a pattern that I have already found using grep, and I know a pattern like "---" that happens a few lines above that certain line number. I want to print out the chunk... (1 Reply)

Dear Friends,
I want to know how to grep for the lines that has a number between given range(start and end).
I have tried the following sed command.

However this requires both start and end to be part of the content being grepped. However... (4 Replies)

In an ideal scenario, I will have a listing of db transaction log that gets copied to a DR site and if I have them all, they will be numbered consecutively like below.

UNBUFFER(1) General Commands Manual UNBUFFER(1)NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected from non-interactive programs. For example, suppose
you are watching the output from a fifo by running it through od and then more.
od -c /tmp/fifo | more
You will not see anything until a full page of output has been produced.
You can disable this automatic buffering as follows:
unbuffer od -c /tmp/fifo | more
Normally, unbuffer does not read from stdin. This simplifies use of unbuffer in some situations. To use unbuffer in a pipeline, use the
-p flag. Example:
process1 | unbuffer -p process2 | process3
CAVEATS
unbuffer -p may appear to work incorrectly if a process feeding input to unbuffer exits. Consider:
process1 | unbuffer -p process2 | process3
If process1 exits, process2 may not yet have finished. It is impossible for unbuffer to know long to wait for process2 and process2 may
not ever finish, for example, if it is a filter. For expediency, unbuffer simply exits when it encounters an EOF from either its input or
process2.
In order to have a version of unbuffer that worked in all situations, an oracle would be necessary. If you want an application-specific
solution, workarounds or hand-coded Expect may be more suitable. For example, the following example shows how to allow grep to finish pro-
cessing when the cat before it finishes first. Using cat to feed grep would never require unbuffer in real life. It is merely a place-
holder for some imaginary process that may or may not finish. Similarly, the final cat at the end of the pipeline is also a placeholder
for another process.
$ cat /tmp/abcdef.log | grep abc | cat
abcdef
xxxabc defxxx
$ cat /tmp/abcdef.log | unbuffer grep abc | cat
$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
abcdef
xxxabc defxxx
$
BUGS
The man page is longer than the program.
