Korn Shell Options

The Korn shell has a number of options that specify your environment and control execution. There are options that cause background jobs to be run at a lower priority, prevent files from being overwritten with redirection operators, disable filename expansion, specify the vi-style in-line command editor, and more.

Table 7.2 lists some of the Korn shell options, along with the default values (these may differ on your system). All of the options are listed in Appendix E.
