Edit file File name : setopt Content :setopt [ {+|-}options | {+|-}o option_name ] [ -m ] [ name ... ] Set the options for the shell. All options specified either with flags or by name are set. If no arguments are supplied, the names of all options currently set are printed. The form is chosen so as to minimize the dif- ferences from the default options for the current emulation (the default emulation being native zsh, shown as <Z> in zshop- tions(1)). Options that are on by default for the emulation are shown with the prefix no only if they are off, while other op- tions are shown without the prefix no and only if they are on. In addition to options changed from the default state by the user, any options activated automatically by the shell (for ex- ample, SHIN_STDIN or INTERACTIVE) will be shown in the list. The format is further modified by the option KSH_OPTION_PRINT, however the rationale for choosing options with or without the no prefix remains the same in this case. If the -m flag is given the arguments are taken as patterns (which should be quoted to protect them from filename expan- sion), and all options with names matching these patterns are set. Note that a bad option name does not cause execution of subse- quent shell code to be aborted; this is behaviour is different from that of `set -o'. This is because set is regarded as a special builtin by the POSIX standard, but setopt is not. Save
