Wait Until You See What Szkielko Pl Can Fix For You
man wait (2) All of these system calls are used to wait for state changes in a child of the calling process, and obtain information about the child whose state has changed. A state change is considered to be: the child terminated; the child was stopped by a signal; or the child was resumed by a signal So wait() allows a process to wait until one of its child processes change its state, exists ... Note that sleep and wait can be very powerful in conjunction, if you want your bash script to wait until it receives a signal. The following script will stop waiting for the sleep to finish if it receives one of the trapped signals. With just the sleep alone, the signal wouldn't be encountered until the sleep has finished.
