Shell Programming and Scripting

Right, I'm sure we all get the question.

I could help with this but I know that the scripting wizards on this forum will do this much more efficiently than me. You've posted to a really high traffic forum here so I'm sure you'll get a response shortly (now the question is clearly defined).

Sorry to create the mess

sdosanjh,

A few questions:-Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.


We're all here to learn and getting the relevant information will help us all.


Perhaps something with grep would be appropriate. You may need a two step process though, one to extract all "insert_job" & "owner" records, and another to select just those for the specified owner.

Different OS and versions have different flags for grep, awk etc., so it's important to know which you have.


Thanks, in advance,

I tried

Code:

egrep "insert_job|owner: autosys"

but that is not working.
I have awk grep working well in the environment

It's unclear what you mean by not working. What output/errors do you get?

You might be better with:-

Code:

egrep "^insert_job|^owner:" infile  >  outfile

Then you have two records for every job. You then need to get every occurrence of owner: autosys a read the previous line.

I did ask a number of questions. Could you answer them so we can work out the best response.



Thanks,
Robin

@rbatte1,
there are no errors; but output is not as per my requirement.
i tried

Code:

 egrep "insert_job|owner: autosys"

; but i am getting all the jobs that are without owner:autosys also. because of OR operator in egrep.

While my requirement is to list only those jobs that are with owner: autosys .

---------- Post updated at 06:47 AM ---------- Previous update was at 06:45 AM ----------

ok Let me please rephrase the requirement.

1. i have file /tmp/a.txt with following entries as an example.

Code:

insert_job: job_A   job_type: c
command: echo "this is test"
machine: abc
owner: autosys
permission: gx,wx
date_conditions: 1
days_of_week: all
start_times: "18:00, 08:00"
alarm_if_fail: 1
timezone: UTC

2. Now i want output as below. (i want those jobs that has owner as autosys only
the output should be

Code:

insert_job: job_A   job_type: c
owner: autosys

If you are getting all the records for both owner that you want and others, then that's a first step. This is why I described it as a two step process. Pass that output into a second grep with appropriate flags and see what you can generate.

Have a read of the manual page for grep and see if you have either the -p flag, or -A & -B as these will probably help you. Not all OSs and versions support all flags, hence why I asked for the details I did.

I do not wish to be rude, but please answer my questions so that we can help you.
