True, that is the downside with the escaping solution. > > How abot this.

The only real solution I can see is something like what here-files use, namely using a magic end-of-block marker, that is also given before each item. Something like this: # EOB ls # EOB # EOB ls # EOB # EOB2 begin # EOB end # EOB2 Which I find extremely ugly. In comparison, I like the escaping soultion better. A third possibility I've considered is to escape each command in the history, but that would severely reduce the greppability of the history file. -- Axel ------------------------------------------------------------------------- Take Surveys.
