Configuration
Environment variables
The following environment variables are available:
- UNZIP - Sets unzip to run with any option.
- UNZIP_OPTS - For use in VMS systems. Does the same as UNZIP (see above).
See the unzip man page for more environment variable information.
Usage
Extracting all the compressed file in the current directory:
user $
unzip temp.zip
Decompressing an archive without creating directories:
user $
unzip -j temp.zip
Forcefully overwrite existing files when decompressing:
user $
unzip -o temp.zip
Decompressing archive to another directory:
user $
unzip temp.zip -d /tmp
See the content of a zip file without decompressing:
user $
unzip -l temp.zip
Exclude certain file during the decompression:
user $
unzip temp.zip -x bashscript.sh -d /tmp
List detailed information about the archive:
user $
unzip -Z temp.zip
Converting text files when decompressing
user $
unzip -a temp.zip
To test our test.zip, printing only a summary message indicating whether the archive is OK or not:
user $
unzip -tq temp.zip
To test all zipfiles in the current directory, printing only the summaries:
user $
unzip -tq '*.zip'
To extract all text source files only '.txt':
user $
unzip temp.zip '*.txt'
To extract only newer versions of the files already in the current directory:
user $
unzip -fo temp.zip
To extract newer versions of the files already in the current directory and to create any files not already there:
user $
unzip -uo temp.zip
Extract a password protected zip file:
user $
unzip -P <password> passwordprotected.zip
Invocation
user $
unzip -h
UnZip 6.00 of 20 April 2009, by Info-ZIP. Maintained by C. Spieler. Send bug reports using http://www.info-zip.org/zip-bug.html; see README for details. Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir] Default action is to extract files in list, except those in xlist, to exdir; file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage). -p extract files to pipe, no messages -l list files (short format) -f freshen existing files, create none -t test compressed archive data -u update files, create if necessary -z display archive comment only -v list verbosely/show version info -T timestamp archive to latest -x exclude files that follow (in xlist) -d extract files into exdir modifiers: -n never overwrite existing files -q quiet mode (-qq => quieter) -o overwrite files WITHOUT prompting -a auto-convert any text files -j junk paths (do not make directories) -aa treat ALL files as text -U use escapes for all non-ASCII Unicode -UU ignore any Unicode fields -C match filenames case-insensitively -L make (some) names lowercase -X restore UID/GID info -V retain VMS version numbers -K keep setuid/setgid/tacky permissions -M pipe through "more" pager See "unzip -hh" or unzip.txt for more help. Examples: unzip data1 -x joe => extract all files except joe from zipfile data1.zip unzip -p foo | more => send contents of foo.zip via pipe into program more unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
