96 Qshell Interpreter (qsh)
All of the single letter options have a corresponding -o option. The option value is
listed in parenthesis following the letter option below. qsh supports the following
options:
-a (allexport)
Set the export attribute to each variable that is assigned a value.
-b (notify)
Enable asynchronous notification of background job completion.
-C (noclobber)
Do not overwrite existing files with the > redirection operator.
-e (errexit)
If the interactive option is not set, exit immediately if any untested command
fails. The exit status of a command is considered to be explicitly tested if
the command is used to control an if, elif, while, oruntil; orifthe
command is the left hand operand of an && or || operator.
-f (noglob)
Disable path name expansion.
-F (float)
Enable floating point arithmetic in arithmetic expressions.
-m (monitor)
Run background jobs in a separate process group and display a message
when the job completes. qsh implicitly turns on this option when the
interactive option is set.
-n (noexec)
If the interactive option is not set, read commands but do not run them. This
is useful for checking the syntax of shell scripts.
-u (nounset)
Write a message to standard error when attempting to expand a variable
that is not set, and if the interactive option is not set exit immediately.
-v (verbose)
Write input to standard error as it is read.
-x (xtrace)
Write each command to standard error before it is run, preceded by the
expansion of the PS4 variable.
Each argument is assigned in order to the positional parameters.
v 0 when successful.
v “export - Set export attribute for variables”
v “readonly - Set read-only attribute for variables”
v “shift - Shift positional parameters”
v “unset - Unset values of variables and functions”
