Thanks you, Thomas! BTW, I have no mentions about this "@" in 'man date', but I have it in 'info date' :P Oh, this way with “@” is the coolest one!
Thanks you, Thomas!

BTW, I have no mentions about this “@” in ‘man date’, but I have it in ‘info date’ :P

The manual command is almost funny: `man date`. With GNU date on Ubuntu, the command is date -d @1168573011, and on NetBSD it’s date -r 1168573011.

I can't figure out how to escape all of the ' and "'s. I would love to have an alias so that I can just type: ctime 11645789. I know I could easily move this same code into a script and put that in my path for the same effect but I'm also running on different machines and it's easier to move an alias than a script . . .

I don't know of any systems that define EPOCH automagically. The example could have been EPOCH=`date +%s` but if you're using date to get an epoch then there is no sense in converting it since a different date argument would get the format you need.

It's easily done without if you know how to nest double-quotes properly: DATE=$(awk "BEGIN { print strftime(\"%c\",$EPOCH) }") Doing everything in awk's BEGIN block ensures that it will not wait for piped input (more efficient again). Bourne shells does variable expansions inside of double-quotes, so $EPOCH gets evaluated properly. The pipe in the awk example is inefficient.
