Hi Don and Rudi,

I am highlighting the part from my original request

Quote:
Also I have a list of scrambled signals which has a shorter string and a longer string separated by // (double slash ). Always the shorter string of a scrambled signal will have the primary signal as a substring and I need to parse out the longest possible primary signal from it.


for this string

Code:
(\\b-[pt22dx]dfdfs/(dsgfspp22dx//[(\pp22dx)-@@----B-@--

only the shorter of the two columns (compared by length separated by //) will have the primary signal, in this case [(\pp22dx)-@@----B-@-- , so the answer is pp22dx.

NAME
pause - suspend process until signal SYNOPSIS
DESCRIPTION
suspends the calling process until it receives a signal. The signal must be one that is not currently set to be ignored or blocked (masked) by the calling process. If the signal causes termination of the calling process, does not return. If the signal is by the calling process and control is returned from the signal-catching function (see signal(5)), the calling process resumes execution from the point of suspension; with a return value of -1 from and set to APPLICATION USAGE
Threads Considerations Signal dispositions (such as catch/default/ignore) are shared by all threads in the process and blocked signal masks are maintained by each thread. Therefore, the signals being waited for should not be ignored by the process or blocked by the calling thread. will suspend only the calling thread until it receives a signal. If other threads in the process do not block the signal, the signal may be delivered to another thread in the process and the thread in may continue waiting. For this reason, the use of is recommended instead of for multi-threaded applications. For more information regarding signals and threads, refer to signal(5). SEE ALSO
