And now, what is the problem. When "connect" is executed for the first time (return code = 150), "getsockopt" in "error_s" return code "146", but after "goto"
when "getsockopt" is executed second time "error_s" is equal "0" (which means connection is established successfully).
Example output:
The same code executed on i.e. Linux CentOS or HPUX, when getsockopt is executed second time, return error codes and inform that there is no connection but in case of Solaris
"getsockopt" works in a strange way.
Please explain what is the problem or how to deal with such behavior on Solaris.
Thanks in advance.

Your sample output does not match what the code you posted would emit. There's no "try connect again!" in your sample output, yet your code would have printed that given the value of errno_s.
Not only that, your code would not compile as the else clause following the goto statement is not valid C or C++ code.
It's hard to know what's going on when the code you post can not produce the output you're seeing.
Also, why are you assuming errno will be reset to zero? Few if any library calls will do that, especially on Solaris, which follows POSIX and other specifications MUCH more closely than Linux does.

It is just a pseudo-code - to show what is the main problem.
OK. So you showed us imaginary output from pseudo-code that won't compile and has never been run. That makes it hard for us to imagine what problems you might run into if you wrote working code and actually looked at the output it might produce.
If you have code that did produce the output you showed us, show us that code! If not, write some code, compile it, run it, and show us the code and the output that was produced by running that code.
We see nothing at all strange about the output produced by getsockopt() on a Solaris system from the pseudo-code you've shown us. If we don't know what you passed to getsockopt(), we can't guess at what any OS might do with the data it was given.

Look at the following data file(cou.data) which has four fields separated by tab.
Four fields are country name, land area, population, continent where it belongs.
As for country name or continent name which has two words, two words are separated by space.

Hi there,
I'm running into a very weird situation. Let's forget about the purpose of my initial script please. I noticed the bug whatever I'm trying to do.
I'm on an old server running bash 3.1.17.
Say we have the following script :

This really puzzles me. The following code gives me the error 'expr: syntax error' when I try to do multi-line comment using here document

I've posted about this before, but only recently narrowed the problem down to a specific cause.
Ok, first of all, the behavior:
It occurs when autocompletion brings up its list (not when there is only a single option). Basically, if I were to type, say,
cd ~/<TAB>
I would get something... (2 Replies)

Is it normal behavior for a shell script that terminates to terminate its parent shell when executed with the "." option?
For example, if I have the example script (we'll name it ex.sh):

exit 2

And I execute it like this:

Hi there,
I have a strange problem and I cannot figure it out what I am doing wrong here.
Let me try to picture it.
In principle it is prety straight forward, but something odd is happening.
