You haven't told us which system and which shell you use, but from your use of the r alias i deduce it is an AIX system. r is an alias itself for:

Code:

fc -e -

I agree with rbatte1, it is a dangerous thing to rely on something spurious like the command history. If you want to repeatedly execute a (group of) command(s) then put them into a script, not an alias.

I hope this helps.
