- .SH DESCRIPTION
- .B unzip
- will list, test, or extract from a ZIP archive, commonly found on MSDOS
- systems.
- Archive member extraction is implied by the absence of the -c, -p, -t,
- -l, -v or -z options. All archive members are processed unless a
- .B filespec
- is provided to specify a subset of the archive members.
- The
- .B filespec
- is similar to an egrep expression, and may contain:
- .sp 1
- .in +8
- .ti -8
- * matches a sequence of 0 or more characters
- .ti -8
- ? matches exactly 1 character
- .ti -8
- \\nnn matches the character having octal code nnn
- .ti -8
- [...] matches any single character found inside the brackets; ranges
- are specified by a beginning character, a hyphen, and an ending
- character. If a '!' follows the left bracket, then the range
- of characters matched is complemented with respect to the ASCII
- character set.
