And when they do, they will see that "$@" is actually the correct expression to use when they want to process all arguments that the script/function was given. text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/scripting/array?rev=1262679647 Create an array % local -a buffer % buffer=(a b c) Create an array with each words of a string % string="Welcome to the real world, Neo" % buffer=(${=string}) Create an array of lines from a file % buffer=("${(f)$(< /etc/hosts)}") % echo $buffer[1] 127.0.0.1 eva-O1.linagora.com eva-01 text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/scripting/paramexp?rev=1262679647 Parameter expansion is one of the most important (and powerful) parts of zsh scripting. Its behaviour may be changed by various modifiers and flags, which will be discussed below. The zshexpn(1) manpage is a detailed reference about every single aspect of parameter expansion. We do not intend to copy its content. So, if the description here may seem a little incomplete, consult the manual to get a complete description. text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/scripting/paramflags?rev=1262679647 Expansion Flags are very powerful. However they are sometimes not that easy to understand by just reading the manual. So, let's look at some examples for their usage.
