cindex(shell flags)
If the tt(-s) flag is not present and an argument is given,
the first argument is taken to be the pathname of a script to
execute. The remaining arguments are assigned to the positional
parameters. The following flags are interpreted by the shell
when invoked:
startitem()
item(tt(-c) var(string))(
Read commands from var(string).
)
item(tt(-i))(
Force shell to be interactive.
)
item(tt(-s))(
Read command from the standard input.
)
enditem()
For further options, which are common to invocation and the tt(set)
builtin, see
ifzman(zmanref(zshoptions))\
ifnzman(noderef(Options))\
. Flags may be specified by name using the tt(-o) option. For example,
example(zsh -x -o shwordsplit scr)
runs the script tt(scr), setting the tt(XTRACE) option by the corresponding
letter `tt(-x)' and the tt(SH_WORD_SPLIT) option by name.
