NAME

       yash - Yet Another Shell

SYNOPSIS

       yash [options] [filename [args...]]
       yash [options] -c command [command_name [args...]]
       yash [options] -s [args...]

DESCRIPTION

       yash  is a command line shell that conforms to the POSIX.1 (IEEE Std 1003.1, 2008 Edition) standard for the most part. Actually, it is much
       more POSIX-compliant than other shell like bash and zsh.

       yash also has its own features beyond POSIX, such as:

	  * global aliases
	  * random numbers
	  * socket redirections and other special redirections
	  * right prompt
	  * command completion

OPTIONS

       set - set shell options and positional parameters
	     set [-abefhmnuvxC] [+abefhmnuvxC] [-o option] [+o option] [--] [arg...]
	     set -o
	     set +o
       The first form enables or disables the specified shell options and/or sets positional parameters to <arg>s. If no  <arg>s  are  given,  the
       positional parameters are not changed.
       If no options or <arg>s are given at all, a list of all existing variables is printed. To clear all positional parameters, use `set --'.
       The second form prints the current settings of the shell options in a human- readable form.
       The third form prints commands that can be used to restore the current option settings later.

       -h, --help
	      Show this help message and exit

       -a --allexport
	      Any variable is exported when assigned.

       -b --notify
	      When the status of a job is changed, it is notified immediately.

       --notifyle
	      Similar to -b, but only notify during line-editing. Ignored if -b is set.

       -e --errexit
	      Exit the shell immediately when any simple command returns a non-zero status.

       +f --glob
	      Perform pathname expansion (globbing).

       --caseglob
	      Perform pathname expansion case-sensitively.

       --dotglob
	      In pathname expansion, `*' and `?' match a `.' at the beginning of the filename.

       --markdirs
	      In pathname expansion, directory pathnames have a `/' at the ends.

       --extendedglob
	      Enable extended pathname expansion.

       --nullglob
	      In pathname expansion, patterns that do not match any pathname are removed from the command line rather than left as is.

       -h --hashondef
	      When a function is defined, all the commands in the function are registered in the command path cache.

       -m --monitor
	      Enable job control. All jobs are run in their own process group.	When the status of a job is changed, the status is reported before
	      the next prompt. This option is enabled by default for an interactive shell.

       +n --exec
	      Execute commands.  This option cannot be disabled in an interactive shell.

       +u --unset
	      Expand an undefined variable to an empty string.

       -v --verbose
	      Echo each command to the standard error before execution.

       -x --xtrace
	      After each command line is expanded, the expanded line is printed to the standard error.

       +C --clobber
	      Allow redirections to overwrite existing files.

       --ignoreeof
	      Do not exit when an EOF is entered.  This option is effective in an interactive shell only.

       --braceexpand
	      Enable brace expansion.

       --curasync, --curbg, --curstop
	      A background job becomes the current job when
		      (curasync)  invoked as an asynchronous command
		      (curbg)	  resumed by the bg built-in
		      (curstop)   stopped.
	      (These options are enabled by default)

       --histspace
	      Do not save lines that start with a space in the history.

       --posixly-correct
	      Make the shell behave as the POSIX shell.

       --vi   Enable vi-like editing.

       --emacs
	      Enable emacs-like editing.

       --le-convmeta
	      Treat 8th bit of input as a meta-key flag (regardless of terminfo).

       --le-noconvmeta
	      Do not treat 8th bit of input as a meta-key flag.

       --le-visiblebell
		   Alert with a flash rather than a bell.

       --le-promptsp
	      Move cursor to beginning of line each time when starting line-editing. (enabled by default)

       --le-alwaysrp
	      Make the right prompt always visible on the screen.

       --le-compdebug
	      Print debugging information during command line completion.

       Options can be disabled by using `+' instead of `-'. For example, `set +a' or `set ++allexport' disables the allexport  option.	 Prefixing
       `no' to a long option also disables the option. For example, `set --nounset' disables the unset option.
