waitfor

Wait until a path exists

Syntax:

waitfor pathname [wait_time]

Runs on:

Neutrino

Options:

pathname

The path to test.

wait_time

The maximum number of seconds to wait for the file to appear. It can include one decimal digit to specify tenths of a second. The default is 5.0 seconds.

Description:

The waitfor utility pauses temporarily until a stat() on the specified pathname succeeds. It's often used for synchronization, to allow a resource manager to perform its startup functionality, and then for the process manager to proceed with the further interpretation of the script file.

Native io-pkt and ported NetBSD drivers don't put entries into the /dev/io-net namespace, so a waitfor command for such an entry won't work properly in buildfiles or scripts. Use if_up -p instead; for example, instead of waitfor /dev/io-net/en0, use if_up -p en0.
