Syntax
int getopt_long ( string argv, string optstring, string long_options))
Description
getopt_long breaks up command lines for easier parsing and legal review. It examines a list of arguments for short or long options.
The function works in posixly correct mode and does not reorder arguments. However, if you unset the POSIXLY_CORRECT environment option, it reorders the argv variable as it scans, placing all nonoptions at the end of the list.
Example
while ((option = getopt_long(args, "vh",{"verbose","help"})) !=""){
print("Matched option",option);
}
Syntax
int getopt_long_only ( string argv, string optstring, string long_options))
Description
getopt_long breaks up command lines for easier parsing. It examines a list of arguments for only long options.
The function works in posixly correct mode and does not reorder arguments. However, if you unset the POSIXLY_CORRECT environment option, it reorders the argv variable as it scans, placing all nonoptions at the end of the list.
Example
while ((option = getopt_long_only(args, "vh",{"verbose","help"})) !=""){
print("Matched option",option);
}
Syntax
int glob ( string pattern, string str )
Description
glob matches a string to a pattern. This match is often used for filenames since the patterns are the same ones that the UNIX shell uses for filename matching.
For more information, see the fnmatch(3) man page.
Returns true if the string matches the pattern, otherwise false.
Example
#this returns true because the “*” wildcard character matches any number of any character
glob("a*b", "axyzb")
#this returns true because the “.” Is interpreted as a literal period char.
glob("a.*b", "a.fgb")
Table 41: Search patterns

Upper or lower case j followed by any number of characters. |
[a-z] |
Any lower case character. |
[^a-z] |
Any character except lower case characters. |
j? |
j followed by a single character. |
