Some people, when confronted with a problem, think 'I know, I'll use regular expressions.' Now they have two problems.

If I want to get the lines 506, 590 and 600 (from text1.log) written to out.log.
The following command allows me to do that:
awk 'NR==506||NR==590 || NR==600' "text1.log" > out.txt
Let us set a=506, b=590 and c=600.
Now what I need is lines 628 (a+(122)*n), 712 (b+(122)*n),
722 (c+(122)*n) ,where n=1-20 written out from text1.log.
Can awk be suitable for this?
Can someone outline how this can be done. I appreciate your help.
If the above needs to be repeated for a series of outputs, text2.log, text3.log, how can this be done? Any help is greatly appreciated.

It would be nice if you left your e-mail address. Sometimes I want to send a private message, or just thank for the great comment. Having your e-mail really helps.

* use <pre>...</pre> to insert a plain code snippet.
* use <pre lang="lang">...</pre> to insert a syntax highlighted code snippet.
For example, <pre lang="python">...</pre> will insert Python highlighted code.
* use <code>...</code> to highlight a variable or a single shell command.
* use <a href="url" nospam>title</a> to insert links.
<a href="url" nospam>title</a>
* use other HTML tags, such as, <b>, <i>, <blockquote>, <sup>, <sub> for text formatting.
