Cannot use funccion $date in home network


Hello
I have a home network. I cannot use the funccion $date. WHen I use it in my PC, it works good, but when I use it to rename folder depende on the $(date) I got bash errors. I think, that is because $(date) create long names with spaces like:

Code:
lun sep  7 14:48:30 CEST 2009
So, there is some problem to create this names in network, that is what I think.

When I use $RANDOM instead $(date) it works good.

Any solution to can use $(date) in network?

Variables or Command Substitution

Greetingz!

I'm a little lost....are you attempting to access the value stored in a Variable, or are you trying to do "Command Substitution" within a shell script?

Specifically, $(date) is not a function, you're calling the "date" command (as in /usr/bin/date), because you're using parenthesis, rather than curly brackets.

Unless you meant ${date} which would call a Variable, which should be set in the script, or your shell's environment files.

If you're trying to get a date added on to the end of a directory's name, you might want to check the manual page ("man date") for the syntax.

Perhaps something like this;

mv directory_name directory_name-`date +%Y_%m_%d-%H%M`

so you wind up with a directory named like this;

directory_name-2009_09_08-0253

Hope this helps!
