hash(1) OSS Shell and Utilities Reference Manual
NAME
hash - Affects memory of where utilities are located
SYNOPSIS
hash [utility ...] -r
FLAGS
-r Causes the hash command to forget all locations of utilities and com-
mands.
DESCRIPTION
The hash command affects the way the current shell environment remembers the locations of
utilities.
When the name of a command or utility is specified for utility, the hash command adds the loca-
tion of that command or utility to its list of remembered locations.
When the -r flag is used, hash forgets all previously remembered locations of utilities and com-
mands.
When utility is not specified and the -r flag is not used, hash reports the contents of its list of
remembered locations.
EXAMPLES
1. The following command lists the commands whose locations the hash
command currently remembers:
hash
NOTES
The hash command is a shell built-in command. It differs from the regular commands in that it
does not open a new shell process when it executes.
A general discussion of shell built-in commands and a list of the OSS shell built-in commands
are in the reference page for sh(1).
