Example uses of the Linux Command zipAn Introductory Tutorial

The following examples illustrate typical uses of the command unzip for unpackaging "archive" files, also called "zip files". The archive files are assumed

to be generated using software such as zip, which uses the s tandard z ip file format.

To use unzip to extract all members of the archive letters.zip into the current directory and subdirectories below it, creating any subdirectories as

necessary:

unzip letters

To extract all members ofletters.zip into the current d irectory only:

unzip -j letters

To test letters.zip, printing only a summary message indicating whether the a rchive is OK or not:

unzip -tq letters

To test allzipfiles in the current d irectory, printing only the summaries:

unzip -tq \*.zip

(The backslash be fore the as terisk is only required if the shell expands w ildcards, as in Unix; double quotes could have been used instead, as in the

source examples below .) To extract to standard output all members ofletters.zipwhose names end in .tex, auto-converting to the local end-of-line

convention and piping the output into more(1):

unzip -ca letters \*.tex | more

To extract the binary file paper1.dvito standard output and pipe it to a printing program:

unzip -p articles paper1.dvi | dvips

To extract all FORTRAN and C source files--*.f, *.c, *.h, and Makefile--into the /tmp directory:

unzip source.zip "*.[fch]" Makefile -d /tmp

(the double quotes are necessary only in Unix and only if globbing is turned on). To extract all FORTRAN and C source files, regardless of case (e.g.,

both *.c and *.C, and any makefile, Makefile, MAKEFILE or similar):

unzip -C source.zip "*.[fch]" makefile -d /tmp

To extract any such files but convert any uppercase MS-DOS or VMS names to low ercase and convert the line-endings of all of the files to the local

standard (without respect to any files tha t might be marked ``binary''):

unzip -aaCL source.zip "*.[fch]" makefile -d /tmp

To extract only newer versions of the files a lready in the current directory, without querying (NOTE: be careful of unzipping in one timezone a zipfilecreated in another--ZIP archives other than those created by Zip 2.1 or later contain no timezone information, and a ``newer'' file from an eastern

timezone may, in fact, be o lder):

unzip -fo sources

To extract newer versions o f the files a lready in the current directory and to create any files not a lready there (same caveat as previous example):

unzip -uo sources

To display a diagnostic screen showing which unzip and zipinfo options are stored in environment variables, whether decryption support was compiledin, the compiler with which unzip was compiled, etc.:

unzip -v

In the last five examples, assume that UNZIP or UNZIP_OPTS is se t to -q. To do a singly quiet listing:

unzip -l file.zip

To do a doubly quiet listing:

unzip -ql file.zip


3/3



(Note that the ``.zip'' is generally not necessary.) To do a standard listing:

unzip --ql file.zip

or

unzip -l-q file.zip

or

unzip -l--q file.zip

(Extra minuses in options don't hurt.)
