Top Forums Shell Programming and Scripting Reading a file that is already open by another process Post 302224715 by bakunin on Wednesday 13th of August 2008 08:57:47 PM

Some file without any content named "ok-file". It is only there if everything has been transferred correctly so if the ftp-process transfers this file, the process knows (by checking for the existence of this file) that everything has been transferred. If the initial check for the existence of the file fails the process would know that the data are incomplete and it has to wait.

I hope this helps.

NAME
wait - await process completion SYNOPSIS
[pid] DESCRIPTION
If no argument is specified, waits until all processes (started with of the current shell have completed, and reports on abnormal termina- tions. If a numeric argument pid is given and is the process ID of a background process, waits until that process has completed. Other- wise, if pid is not a background process, exits without waiting for any processes to complete. Because the system call must be executed in the parent process, the shell itself executes without creating a new process (see wait(2)). Command-Line Arguments supports the following command line arguments: The unsigned decimal integer process ID of a command, whose termination is to wait for. WARNINGS
Some processes in a 2-or-more-stage pipeline may not be children of the shell, and thus cannot be waited for. SEE ALSO
csh(1), ksh(1), sh-posix(1), sh(1), wait(2). STANDARDS CONFORMANCE
