Aliases are useful for specifying the default version of a command that exists in several versions on your<br />
system, or to specify default options to a command. Another use for aliases is for correcting incorrect spelling.<br />
The first word of each simple command, if unquoted, is checked to see if it has an alias. If so, that word is<br />
replaced by the text of the alias. The alias name and the replacement text may contain any valid shell input,<br />
including shell metacharacters, with the exception that the alias name may not contain "=". The first word of<br />
the replacement text is tested for aliases, but a word that is identical to an alias being expanded is not<br />
expanded a second time. This means that one may alias ls to ls -F, for instance, and <strong>Bash</strong> will not try to<br />
recursively expand the replacement text. If the last character of the alias value is a space or tab character, then<br />
the next command word following the alias is also checked for alias expansion.<br />
Aliases are not expanded when the shell is not interactive, unless the expand_aliases option is set using<br />
the shopt shell built-in.<br />

<strong>Bash</strong> <strong>Guide</strong> for <strong>Beginners</strong><br />
Aliases are created using the alias shell built-in. For permanent use, enter the alias in one of your shell<br />
initialization files; if you just enter the alias on the command line, it is only recognized within the current<br />
shell.<br />
