At least these are fun tips for me.
Fun with epoch dates
Unix does a great job of storing time as a long integer value. They call this time Epoch and it marks the seconds in time from January 1, 1970 at midnight. I see these times in various logs and have wrote programs to convert them. There is an easy way to do this at the command prompt. Just us the '@' sign in front of the value.
date -d @1234567890
To use date to dump the epoch time:
date +%s
