Not much different to mine, must be normal:
Code:
bash-4.1$ type cat
cat is /usr/bin/cat
bash-4.1$ type ls
ls is /usr/bin/ls
bash-4.1$
It's a bash builtin, see man bash. Relevant bit here:
Quote:
type [-aftpP] name [name ...]
With no options, indicate how each name would be interpreted if used as a command name. If the -t option is used, type prints a string which is one of alias, keyword, function, builtin, or file if name is an alias, shell reserved word, function, builtin, or disk file, respectively. If the name is not found, then nothing is printed, and an exit status of false is returned. If the -p option is used, type either returns the name of the disk file that would be executed if name were specified as a command name, or nothing if ''type -t name'' would not return file. The -P option forces a PATH search for each name, even if ''type -t name'' would not return file. If a command is hashed, -p and -P print the hashed value, not necessarily the file that appears first in PATH. If the -a option is used, type prints all of the places that contain an executable named name. This includes aliases and functions, if and only if the -p option is not also used. The table of hashed commands is not consulted when using -a. The -f option suppresses shell function lookup, as with the command builtin. type returns true if all of the arguments are found, false if any are not found.

do you mean
Code:
type ls
ls is aliased to `ls --color=auto'
is an error? No, it is normal, you have an alias defined for ls. You can check your aliases by typing the command alias.
try which ls
