hash

create a tracked alias 

KornShell Built-in


SYNOPSIS

hash [name ...]

hash -r


DESCRIPTION

hash creates one or more tracked aliases. Each name on the command line becomes an alias that is resolved to its full path name; thus the KornShell avoids searching the PATH directories for the command whenever you invoke it. A tracked alias is assigned its full path name the first time that the alias is used. It is re-assigned a path name the first time that it is used after the variable PATH is changed or the shell command cd is used.

hash is a built-in alias defined with

alias hash='alias -t'

If you specify hash without any arguments on the command line, hash displays the current list of tracked aliases.

Options

-r 

removes all current tracked aliases.


DIAGNOSTICS

Possible exit status values are:

0 

Successful completion.

1 

Failure because of an invalid command line option.
