Since all PC operating systems allow spaces in filenames, unzip by default extracts filenames with spaces intact e. However, it may be highly suspicious to make use of this Unix "feature". File comments are created with the -c option of zip 1or with the -N option of the Amiga port of zip 1which stores filenotes as comments.
On VMS, see also -S. This safety feature new for version 5. The default is to exploit the destination file system, preserving case and extended file name characters on an ODS5 destination file system; and applying the ODS2-compatibility file name filtering on an ODS2 destination file system.
A similar scenario takes place when the sequence number range for numbered backup files gets exhaustedor for bit systems. Note that under many operating systems, the TZ timezone environment variable must be set correctly in order for -f and -u to work properly under Unix the variable is usually set automatically.
Use this option with extreme caution. This option results in setting the timestamps for all extracted entries to the current time. By default unzip queries before extracting any file that already exists; the user may choose to overwrite only the current file, overwrite all files, skip extraction of the current file, skip extraction of all existing files, or rename the current file.
In contrast to most of the competing utilities, unzip removes the 12 additional header bytes of encrypted entries from the compressed size numbers. On Tandem, -a is enabled by default, see above.
Nothing but the file data is sent to stdout, and the files are always extracted in binary format, just as they are stored no conversions. See -f above for information on setting the timezone properly. This option has evolved and now behaves as both an option and a modifier. On some systems the number of available lines on the screen is not detected, in which case unzip assumes the height is 24 lines.
Without the -x option, all C source files in all directories within the zipfile would be extracted. However, when the -: This option performs the same function as the -f option, extracting with query files that are newer than those with the same name on disk, and in addition it extracts those files that do not already exist on disk.
By specifying -D, unzip is told to suppress restoration of timestamps for directories explicitly created from Zip archive entries.
Doubling the option -bb forces all files to be extracted in this format. The handling of filename codings within unzip falls back to the behaviour of previous versions.
By default unzip queries before overwriting, but the -o option may be used to suppress the queries. Many multi-user operating systems provide ways for any user to see the current command line of any other user; even on stand-alone systems there is always the threat of over-the-shoulder peeking.
Be sure to quote any character that might otherwise be interpreted or modified by the operating system, particularly under Unix and VMS.
