41 The following options are available:
44 When extracting a text file, convert DOS-style line endings to
45 Unix-style line endings.
47 Match file names case-insensitively.
49 Extract to stdout/screen.
50 When extracting files from the zipfile, they are written to stdout.
53 but doesn't suppress normal output.
55 Extract files into the specified directory rather than the current
59 Extract only files from the zipfile if a file with the same name
60 already exists on disk and is older than the former.
61 Otherwise, the file is silently skipped.
63 Ignore directories stored in the zipfile; instead, extract all files
64 directly into the extraction directory.
66 Convert the names of the extracted files and directories to lowercase.
68 List, rather than extract, the contents of the zipfile.
71 When extracting a file from the zipfile, if a file with the same name
72 already exists on disk, the file is silently skipped.
75 When extracting a file from the zipfile, if a file with the same name
76 already exists on disk, the existing file is replaced with the file

87 Test: do not extract anything, but verify the checksum of every file

92 already exists on disk, the existing file is replaced with the file
93 from the zipfile if and only if the latter is newer than the former.
