Re^3: help needede in backticks(``) and system function by ikegami (Patriarch) on Feb 10, 2006 at 01:41 UTC
Yes, the parent will wait in both cases. Unless you do execute something like `command &` (unix) or `start command` (Windows). `fork`+`exec` doesn't wait. IPC::Open3 doesn't wait. IPC::Run can do both. The special syntax `system 1, ...` in Windows doesn't wait.	[reply] [d/l] [select]
