Get them all! (unalias -a) aliases make scripts non portable and hard to debug as you found. unalias [-a] [name ...] Remove each name from the list of defined aliases. If -a is supplied, all alias definitions are removed. The return value is true unless a supplied name is not a defined alias. Since this is a script in /root/ I assume it is running more often as root than not. Thus, a better solution in this case might be CP=/bin/cp $CP /tmp/a /tmp/b This lets you use the safer $CP in your script. The advantage is that trojan programs/ scripts that might be hidden in $PATH will not be found. This is very important for systems where a person might "su" in contrast to "su - ". i.e. The first ("su") does not tidy up $PATH and bad things might happen. Since this is in /root the script should also be setting $PATH and not depending on it. Do compare and contrast CP=/bin/cp and CP="/bin/cp "! Other scripts (application drivers) often depend on the users $PATH so full path names are the most common solution. For completeness \cp also works to squash the alias. -- T o m M i t c h e l l spam unwanted email. SPAM, good eats, and a trademark of Hormel Foods.
