Common options include;
- -f - 'freshen' existing files; extract only those files that already exist on disk and that are more recent than those files on disk
- -u - as -f but also extract files that do not already exist on disk
- -B - save a backup copy of each file overwritten, with a tilde appended (only if compiled with UNIXBACKUP defined)
- -j - junk paths; extract all files to current or specified (with -d) directory, ignoring the archive's directory structure
- -n - never overwrite existing files
- -l - list files in archive(s)
- -t - test integrity of archive(s)
file-list - specify one or more zip archive files, separate multiple file names with spaces
-d directory - extract files to specified directory (default is to current directory)
-x file-list - exclude the specified file or files from processing by unzip
Usage Examples
unzip /etc/test - extract files (and file directory structure) from archive /etc/test.zip to the current directory
unzip -j test -d /test/temp/ - extract files from archive test.zip to the current directory, ignoring the archive's directory structure
unzip -n test* -x test8 - extract files (and file directory structure) from all archives with filenames starting test with the exception of archive test8.zip
Usage Notes
Unless the -d option is used files are extracted to the current directory
