Concurrent writing to file
Hi
I have a ksh that can have multiple instances running at the same time. The script (each instance) uses the SAME log file to write to. Should this cause a problem or is the ksh clever enough to queue write requests to the file? Thanks. GMMIKE

ksh will not do anything special to help you. Use append mode. That is do NOT use >. Use >> instead...
echo something >> logfile The kernel ensures that multiple processes writing to files in append mode do not step on each other's data.
