shell for a while, you will probably find that there are some commands

alias is a personalized name that stands for all or part of a command.
You can create an alias by entering:
in response to the shell's usual prompt for input. This
is not a normal command; it is an instruction to the shell itself.For example, suppose you have a hard time remembering that the mv command

would enter:

Tip: If you issue an exec sh, alias names are not exported. For information about how to put alias definitions in your login script pointed to by the ENV variable, see Customizing your shell environment: The ENV variable. DBCS recommendation: We recommend that you use single-byte characters when specifying an alias name, because the POSIX standard states that alias names must contain only characters in the POSIX portable character set. |
