Shell Programming and Scripting

You provided no context. They are wrong in the "Unix" context (which is what you called it) as they apply only to certain commands (or is it only one command?).

Do you think the search and replace command wont work?
I gave in terms of vi usage.

It will work as I explained..

And $ has that meaning which I explained, in that command context.

Hi Johnson,

I used the command you gave to me but still I'm not getting any output

grep "^[ ]*Jobstart time" inputfile_jobstart_grep | cut -f2 -d =


Thanks,
Raju

Then the file doesn't contain any lines with the pattern you gave.

Hi Strangfeld,

If I use your commad It will give me the output as 2 . since in the input file had two time stamp fields with seperator = like below

Job start time=2009-10-16 11:04:48 Job elapsed time=00:02:34

I want to get 2009-10-16 11:04:48 from the file inputfile_jobstart_grep




Thanks,
Raju

Hi Johnson,

Here is the content in the file inputfile_jobstart_grep

DBsetup DFmodify infilter Uvchange Uvdelete Uvread Uvtlconvert Uvwrite acct.restore anlyze basic block catalog cdict claccount clear.file cname conf.file create.file Job start time=2009-10-16 11:04:48 Job elapsed time=00:02:34 jobstatus=2

The one which I highlighted in green contains the Job start time so I need to get the timestamp portion of it


I tried below command

grep "^[ ]*Job start time" inputfile_jobstart_grep | cut -f2 -d =

but no result


Thanks,
Raju

Your pattern matches the beginning of the line.
What you are searching for is in the middle of the line.

So I guess I must be misunderstanding you or can you please try to describe in another way.

What I assume by reading the above statement is that you have a simple text file which has line items such as what you posted above:

Code:

DBsetup DFmodify infilter Uvchange Uvdelete Uvread Uvtlconvert Uvwrite acct.restore anlyze basic block catalog cdict claccount clear.file cname conf.file create.file Job start time=2009-10-16 11:04:48 Job elapsed time=00:02:34 jobstatus=2 
DBsetup DFmodify infilter Uvchange Uvdelete Uvread Uvtlconvert Uvwrite acct.restore anlyze basic block catalog cdict claccount clear.file cname conf.file create.file Job start time=2009-10-17 10:04:48 Job elapsed time=00:02:34 jobstatus=3
DBsetup DFmodify infilter Uvchange Uvdelete Uvread Uvtlconvert Uvwrite acct.restore anlyze basic block catalog cdict claccount clear.file cname conf.file create.file Job start time=2009-10-18 11:24:38 Job elapsed time=00:03:34 jobstatus=2
And so on?

Or are you saying that you are creating the above output by running some grep, sort, awk, sed whatever commands on some source data which you have not shown yet?
