This manual page does not describe a program, but rather a facility that is common to several programs. In particular, several SDDS programs use a common convention for wildcards in element names.
The characters *, ?, [, ], and are used for wildcard operations.
[] * matches any zero or more characters. A sequence like *a matches zero or more
characters up to the first occurence of a.
[] ? matches any one character.
[] [rangeSpec] matches any one character in rangeSpec. rangeSpec is
composed on any number of explicit characters, plus character ranges specified as firstChar-lastChar,
which matches any character between firstChar and lastChar inclusive in the ASCII character set.
For example, [a-z] would match a lower case alphabetic character, while [a-z][A-Z][0-9] would
match any alphanumeric character.
[] [ rangeSpec] matches any one character not in rangeSpec.
