So, where do we start? Being an electronics engineer, is the assumption correct that you know what a specification is? Loosely phrased, the description of a target (contents, shape, structure, timing) and the collection of basic data (setup, sample input, ...) to start from, constraints and/or exceptions and/or boundary conditions, tools available (or forbidden), sometimes accompanied by ideas or even rules/instructions on how to get there.
Still online? Let's start with
The target: Paraphrased from your post#1: A list of directories with the information "contains valid/invalid files". Please refine to taste.
The basics: A number of subdirectories in your home directory (definition varies in above posts) with files to be searched for keywords. Please be very aware that we don't know anything about your computer/(file-) system/directory structure/anything. So some samples might help!
Additional info needed:
- What flexibiltiy is required?
- Do the subdirs change a lot?
- Are there more subdirs?
- - How to define the interesting ones?
- - How to exclude the others?
- - Use a "white list" (= config file)?
- Do the keywords change?
- - How to provide?
- - Are there more than one keyword per subdir?
- config files to be used?
- - one? many?
- - structure of the config file(s)
- - up to the service provider?
Constraints/exceptions/boundary conditions:
- not (yet) known
The tools: available *nix commands/versions (your Solaris have may some restrictions that other OS don't have)
- pure shell (which do you use?)
- text processing commands (sed, awk, perl, ...)
- up to the service provider?
I'll stop here with this non-exhaustive list. Feel free to complete and answer.
You now may say: "What an immense effort for a minor task like a mere 'file list for 7 directories' ". I'd request you to ponder the overall time it took for the two of us to type posts #1 to #10 compared to you making up your mind and put together a small set of basic data, stringent rules, and a precise, distinct result, with which a satisfactory solution would have been proposed within hours if not minutes.
I'd propose you take a step back and try to rephrase your request considering at least part of above...

Hi,
Want to know, is there any way to restrict a Solaris user to Single Login. Means a particular user can login once and if he or someone else tries to login with his ID then a message displayed "user already logged in" and denies his attempt.

continue
break(1) User Commands break(1)
NAME
break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until loop
SYNOPSIS
sh
break [n]
continue [n]
csh
break
continue
ksh
*break [n]
*continue [n]
DESCRIPTION
sh
The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.
The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.
csh
The break utility resumes execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current
line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.
The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.
ksh
The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified, then break n levels. If n is
greater than the number of enclosing loops, the outermost enclosing loop shall be exited.
The continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-
th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words that follow a command preceded by ** that are in the format of a variable assignment are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign, and also that word splitting and file name genera-
tion are not performed.
