ZIP archives, as well as use many different compressors. On the other hand, there are a number of other compression tools named similarly: 7-Zip, gzip, bzip2, rzip, etc.

In case you don't want the parent directory to be included: cd dir1; zip -r.. I'm confused, I did this and get a long list of inflations and extractions but when I check the directory it is empty, save for the original zip file? Where is it all going? For the record, use unzip -d myfolder squash. This mimics how most UI unzip tools work. Show 1 more comment. You can zip files up in compressed format with the GNU tar program: tar -zcvf myfile.

To unzip that file, use: tar -zxvf myfile. Or use tar jcvf file. I downvoted your answer because the question is about how to deal with zip archives not tar files. Starfish, that's certainly within your rights, thanks for at least explaining why, so many people don't take the time to do that :- I took "zip" in the more generic sense compression rather than a specific format, so I'll make that more clear. Be aware that tar archives may not work correctly when moving between different platforms, mac to linux or vice versa.

Zip is much safer, as it works correctly on all systems. I suppose technically this is gzip, so that's fine. I guess. Pretty obviously not what the question asked for though. If you don't have zip and unzip packages installed and you have java, you can use jar to unzip: jar -xf file. Not my server, no unzip, zip, 7z, nothing And this worked. This is a great tip.

We need jdk in advance to execute this command. Compressing: 7za a archive. If you want to use the same compression algorithm with your tarballs, use the -J switch with tar : tar cJf archive.

Bind that to a and creating an archive becomes a arc. Starfish Starfish 3 3 silver badges 12 12 bronze badges. I know this is an old thread but this is the best answer.

Doesn't talk about 7z or tar, its concise and straight to the point — Kyle. BSD Tar can also do this bsdtar -a -c -f sunday. You can use the —t option with the zip command to test the file first. Enter the following:. Some zip files have several different files included in them.

You can extract all of them, or you can exclude some of them. To view a list of the contents of a zip file use the -l option with the zip command:. To specify that you want to unzip the files to a different destination than the directory you are in, type the command:. The —d switch tells the system to put the unzipped files somewhere else.

This article has explained how to unzip and access the content of zip files in Ubuntu Linux. Introduction If you downloaded a file that ends in. Was this article helpful? Vladimir Kaplarevic. The current mapping is as follows: 1 success for normal exit, 0x7fff for warning errors, and 0x7fff?

BUGS Multi-part archives are not yet supported, except in conjunction with zip. This will definitely be corrected in the next major release. Archives read from standard input are not yet supported, except with funzip and then only the first member of the archive can be extracted.

Archives encrypted with 8-bit passwords e. However, the code may fail to detect the correct wrapping locations. First, TAB characters and similar control sequences are not taken into account, they are handled as ordinary printable characters. The correct handling of tabs would require the implementation of a query for the actual tabulator setup on the output console. Dates, times and permissions of stored directories are not restored except under Unix. On Windows NT and successors, timestamps are now restored.

This problem appears to be fixed, but control-C or control-Break can still be used to terminate unzip. This was apparently due either to a hardware bug cache memory or an operating system bug improper handling of page faults? Basically the only file types restored by unzip are regular files, directories and symbolic soft links. This is a limitation of the operating system; because directories only have a creation time associated with them, unzip has no way to determine whether the stored attributes are newer or older than those on disk.

Smith v2. Path of the ZIP archive s. If the file specification is a wildcard, each matching file is processed in an order determined by the operating system or file system.

Only the filename can be a wildcard; the path itself cannot. Be sure to quote any character that might otherwise be interpreted or modified by the operating system, particularly under Unix and VMS. If no matches are found, the specification is assumed to be a literal filename; and if that also fails, the suffix. An optional list of archive members to be processed, separated by spaces.

Regular expressions wildcards may be used to match multiple members; see above. Again, be sure to quote expressions that would otherwise be expanded or modified by the operating system. An optional list of archive members to be excluded from processing.

Without the -x option, all C source files in all directories within the zipfile would be extracted. An optional directory to which to extract files. By default, all files and subdirectories are recreated in the current directory; the -d option allows extraction in an arbitrary directory always assuming one has permission to write to the directory.

This option need not appear at the end of the command line; it is also accepted before the zipfile specification with the normal options , immediately after the zipfile specification, or between the file s and the -x option.

The option and directory may be concatenated without any white space between them, but note that this may cause normal shell behavior to be suppressed. If the first option on the command line is -Z , the remaining options are taken to be zipinfo 1L options.

See the appropriate manual page for a description of these options. This option is similar to the -p option except that the name of each file is printed as it is extracted, the -a option is allowed, and ASCII-EBCDIC conversion is automatically performed if appropriate. This option is not listed in the unzip usage screen. By default unzip queries before overwriting, but the -o option may be used to suppress the queries.

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. The names, uncompressed file sizes and modification dates and times of the specified files are printed, along with totals for all files specified.
