Description:
See attached script (mgz -help)

 

I am using signals, "trap", and "wait" to control a given number of threads in the background. Initially I setup signals handlers that trap SIGUSR2 and execute a new thread, then I execute the number of threads given, and I wait for the threads in the background to complete with the "wait" command. In previous versions - "GNU bash, version 2.05.8(1)-release (i386-redhat-linux-gnu)" this script works just fine, as "wait" is waiting for all background jobs, including the ones started *after* the wait command started waiting. However in the latest release "wait" only waits for the jobs started before the wait command, and the ones started after are not waited on.

 

Repeat-By:
You can use this to test correct function of the script:

mgz 'sp=$(($RANDOM%10)); sleep $sp; echo File "[$tfile]" slept $sp' 2 file1 file2 file3 file4 file5 file6 file7 file8 file9
