getopt(1) General Commands Manual getopt(1)
NAME
getopt - parse command options
SYNOPSIS
optstring args
DESCRIPTION
is used to break up options in command lines for easy parsing by shell procedures and to check for legal options. optstring is a string of
recognized option letters (see getopt(3C)). If a letter is followed by a colon, the option is expected to have an argument, which may or
may not be separated from it by whitespace.
The positional parameters ...) of the shell are reset so that each option is preceded by a and is in its own positional parameter; each
option argument is also parsed into its own positional parameter.
recognizes two hyphens to delimit the end of the options. If absent, places at the end of the options.
The most common use of is in the shell's command (see the example below) where converts the command line to a more easily parsed form.
writes the modified command line to the standard output.

If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
able.
If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable
contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
Single-byte and multibyte character code sets are supported.
DIAGNOSTICS
prints an error message on the standard error when it encounters an option letter that is not included in optstring.
EXAMPLES
The following code fragment processes the arguments for a command that can take the options or and the option which requires an argument:
This code accepts any of the following as equivalent:
WARNINGS
