Shell Including date in filename

[balanga]

I was looking for a way of including the date in a filename and can across this answer. So I tried touch "$(date +"%Y_%m_%d_%I_%M_%p").log" and touch $(date +"%Y_%m_%d_%I_%M_%p").log and both returned:-

Illegal variable name.

How can I do this under FreeBSD?

 

[trev]

touch "`date +"%Y_%m_%d_%I_%M_%p"`.log"

 

[Vull]

/bin/sh -c 'touch "$(date +"%Y_%m_%d_%I_%M_%p").log"'

 

[balanga]

touch "`date +"%Y_%m_%d_%I_%M_%p"`.log"

I figured it out eventually, after a bit of trial and error, slightly different... ie without quotes (")

touch todays-$(date +"%m_%d_%Y").log

touch todays-$(date +"%m_%d_%Y").log

It's more elegant this way $(), also you avoid confusing ' with `.

Just noticed my paste didn't work properly... should have been:-
touch todays-[ICODE]date +"%m_%d_%Y"[/ICODE].log

Hmmm.... seems like embedding the command in a CMD tag strips of the backticks... Here it is as a CODE fragment:-

touch todays-`date +"%m_%d_%Y"`.log2

Can you post your command line, as I'm not sure what you mean...

Use echo $(date) instead of

echo `date`

.

Edit: Annoying, the forum software automatically translates backticks to an [icode] block, even if you enclose it in [noparse]. Another reason not to use backticks.
