autoload
Official Description
autoload is an alias for typeset -fu.
Syntax
autoload function_name
Options
None
Oddities
autoload enables the shell to recognize a name as a function name (-f) but not bother reading the function until it is actually needed (-u leaves the function undefined). This saves shell processing time in the event that the function is never used during the script run.
Example
$ cat funca function funca { print "In funca" } $ $ print $FPATH $ $ pwd /home/obrien $ $ FPATH=/home/obrien # FPATH variable must include path # of file containing function $ $ autoload funca # Make ksh aware of function funca $ $ typeset –f # Not loaded yet typeset -fu funca mc() { mkdir -p ~/.mc/tmp 2> /dev/null chmod 700 ~/.mc/tmp MC=~/.mc/tmp/mc$$-"$RANDOM" ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
