bash - Why does tee wait for all subshells to finish? -


i have server script runs mysqld , forks continue running. example:

./mysqld <parameters> & echo "parent runs next line in script." <do more stuff>

why tee wait child process end before ends itself?

edit:

for example, following hangs:

./myscript | tee -a logfile.log

because can't sure has tee'd output if child process still running.
