- .br
- UnZip is used to extract files compressed and packaged by Zip (see HELP ZIP
- for information on ZIP).
- .sk
- For a brief help on Zip and Unzip, run each without specifying any
- parameters on the command line.
- .sk
- UNZIP will list, test, or extract from a ZIP archive. ZIP archives are commonly
- found on MS-DOS systems; a VMS version of ZIP can also be found here.
- .sk
- 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 filespec is provided to
- specify a subset of the archive members. The filespec is similar to an egrep
- expression, and may contain:
- .sk
- .literal
- * matches a sequence of 0 or more characters
- ? matches exactly 1 character
- \nnn matches the character having octal code nnn
- [...] 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.
- .end literal
- .sk
- Format:
- .sk;.lm+1;.literal
- UNZIP [-cflptuvxz[ajnoqUV]] file[.zip] [filespec...]
- .end literal;.lm-1

- 2 Parameters
- .sk;.indent -4
- file[.zip]
- .sk
- File specification for the ZIP archive. The suffix .ZIP is applied if the
- specified file does not exist. Note that self-extracting ZIP files are
- supported; just specify the .EXE suffix yourself.
- .sk;.indent -4
- [filespec]
- .sk
- An optional list of archive members to be processed. Expressions may be
- used to match multiple members. Expressions should be enclosed in double-quotes
- to prevent interpretation by DCL. Multiple filenames should be separated by
- blanks.

- 2 Options
- .br
- The default action of UnZip is to extract all zipfile entries. The following
- options and modifiers can be provided:
- .sk;.literal
- -c extract files to SYS$OUTPUT (terminal)
- -f freshen existing files (replace if newer); create none
- -l list archive files (short format)
- -p extract files to SYS$OUTPUT; no informational messages
- -t test archive files
- -u update existing files; create new ones if needed
- -v list archive files (verbose format)
- -x extract files in archive (default)
- -z display only the archive comment
- .end literal;.sk;.literal
- MODIFIERS
- -a convert to VMS textfile format (only use for TEXT files!)
- -j junk paths (don't recreate archive's directory structure)
- -n never overwrite existing files; don't prompt
- -o OK to overwrite files without prompting
- -q perform operations quietly (-qq => even quieter)
- -U leave filenames uppercase if created under MS-DOS, VMS, etc.
- -V retain (VMS) file version numbers
- -X restore owner/protection info (may require privileges)
- .end literal
