How do I create an array from a file using every 3rd line
A file contains the following information shown below. Every ceName has 2 consecutive lines that have to be evaluated, using awk, sed, cut (any common unix tools).

Input file:
Code:
ceName: Node-1
processName: tzMgmt
Status: PROCESS_NOT_RUNNING
ceName: Node-2
processName: tzMgmt
Status: PROCESS_RUNNING
ceName: Node-1
processName: XDM
Status: PROCESS_NOT_RUNNING
ceName: Node-2
processName: XDM
Status: PROCESS_RUNNING

To become:

Code:
processName        Status Node-1                   Status Node-2
-----------        -------------------              -------------------
tzMgmt              PROCESS_NOT_RUNNING        PROCESS_RUNNING
XDM                  PROCESS_NOT_RUNNING        PROCESS_RUNNING

Any advice appreciated.

Thanks,

Bjoern

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Thanks for the reply, but the text you put into [code - /code] is not really code but text.

Try this and see if you can modify it to your requirement:
Code:
sed 'N;N;N;N;N;s/\n/\t\t/gp' file

FYI: You put your data / input / output etc also between [CODE]
This will make it easy to read.

This works, but not the best way.
Lets see if any one else comes up with a better one.
Code:
sed  '/ceName:.*/d; s/^[^:]*: //' 3rdline.txt | sed 'N;N;N;s/\n/\t/g; s/\(^[^\t]*\t[^\t]*\t\)[^\t]*\t\([^\t]*\)$/\1\2/'

This is a little more refined:
Code:
sed  '/ceName:.*/d; s/^[^:]*: //' 3rdline.txt | sed 'N;N;N;s/\n/\t/g; s/\([^\t]*\t\)//3'

Code:
awk 'ORS=NR%3?"~":"\n"' alltr.out > alltr.sql
