One other gotcha from traditional Unix to Linux, for administrators, is the icps command, which didn't use to exist, and which took 2 commands to replicate on Linux. I used the ipcs -mop command to retrieve information about the shared memory segments being used. The command in Linux doesn't use those switches. Your mileage may vary.
Does anyone know for sure? I'm about the leave the U2 world as work is taking me a different direction. Actually, I was laid off and am seeking employment and it seems the opportunities in the U2 field are almost non-existent for someone who has to stay around to care for aging parents.
