只需從Internet下載一個.zip文件。我想使用終端解壓縮文件。正確的方法是什麼?
如何從終端解壓縮zip文件?
You can simply use unzip
.
Install it:
apt-get install unzip
And use it:
cd /path/to/file
unzip file.zip
If the unzip
command isn't already installed on your system, then run:
sudo apt-get install unzip
After installing the unzip utility, if you want to extract to a particular destination folder, you can use:
unzip file.zip -d destination_folder
If the source and destination directories are the same, you can simply do:
unzip file.zip
You can use:
unzip file.zip -d somedir
to extract to yourpath/somedir
If you want to extract to an absolute path, use
sudo unzip file.zip -d /somedir
A more useful tool is 7z
, which zips and unzips a range of compression formats, notably lzma
, usually the protocol offering the highest compression rates.
This command installs 7z
:
sudo apt-get install p7zip-full
This command lists the contents of the zip:
7z l zipfile.zip
This command extracts the contents of the zip:
7z x zipfile.zip
If the source and destination directories are the same, you can simply do:
unzip filename.zip
Here is the detailed description of options that I find useful:
Command: unzip -[option] zip-path. -d an optional directory to which to extract files -l List archive files. -P password Use password to decrypt encrypted zipfile entries (if any). -t Test archive files with cyclic redundancy check. -u Update the existing files. -z archive comment
I prefer bsdtar
to unzip
/zip
. For extracting, they are pretty similar:
bsdtar -x -f /one/two/three/four.zip -C /five
unzip /one/two/three/four.zip -d /five
However for zipping, bsdtar
wins. Say you have this input:
/one/two/three/alfa/four.txt
/one/two/three/bravo/four.txt
and want this in the zip file:
alfa/four.txt
bravo/four.txt
This is easy with bsdtar
:
bsdtar -a -c -f four.zip -C /one/two/three alfa bravo
zip does not have the -d
option like unzip, so you have no way to achieve the above unless you cd
first.
Using scripting tools: Perl and Python
Many answers here mention tools that require installation, but nobody has mentioned that two of Ubuntu's scripting languages, Perl and Python, already come with all the necessary modules that allow you to unzip a zip archive, which means you don't need to install anything else. Just use either of the two scripts presented below to do the job. They're fairly short and can even be condensed to a one-liner command if we wanted to.
Python
#!/usr/bin/env python3
import sys
from zipfile import PyZipFile
for zip_file in sys.argv[1:]:
pzf = PyZipFile(zip_file)
pzf.extractall()
Usage:
./pyunzip.py master.zip
or
python3 pyunzip.py master.zip
Perl
#!/usr/bin/env perl
use Archive::Extract;
foreach my $filepath (@ARGV){
my $archive = Archive::Extract->new( archive => $filepath );
$archive->extract;
}
Usage:
./perlunzip master.zip
or
perl perlunzip.pl master.zip

Install unzip ============= So First of all we need to install unzip on our system if it’s not installed. unzip command is used to extract files from a ZIP archive.
Run the following command to install
unzip
sudo apt-get install unzip
unzip
Syntex$ unzip [-aCcfjLlnopqtuvy] [-d dir] zipfile
Now Follow the steps below:
UnZip File
OPTION 1 – If the Zip File is in the same directory/folder in which your terminal is and we want to extract it in the present working directory.
Use the following command to achieve the above described scenario
sudo unzip zip_file_name.zip
if the zip file is protected with some password, then use the following command :
sudo ubzip -P zip_file_name.zip
Please make sure you use -P (capital P) not -p because the are different options.
OPTION 2 – If the zip file is not present in the same directory and we want to extract/unzip the file in different directory.
Use the following command to achieve the above described scenario
sudo unzip path/filename.zip -d another_path_or_same_path
if we does not use option -d the file will be extracted to present working directory.
And if the zip file is password protected we can also use
-P
.use tar Command in Linux / Unix
tar
is an acronym for Tape Archive. tar command is used to Manipulates archives in Linux/Unix. System administrators uses tar command frequently to rip a bunch of files or directories into highly compressed archive which are calledtarball
ortar
,bzip
andgzip
in Linux/Unix system.tar Syntex
tar [OPTION...] [FILE]...
Or
tar required Flags
tar {-r|-t|-c|-x|-u}
tar optional Flags
tar {one of the required Flags} [ -d ][-B] [ -F ] [ -E ] [ -i ] [-h ] [ -l ] [ -m ] [ -o ] [ -p ] [ -w] [ -s ] [ -U ] [ -v ] [-Number] [-b Blocks] [-f Archive]
Examples
Create tar Archive File by Compressing an Directory or a Single File
The terminal command below will create a
.tar
file calledsample_dir.tar
with a directory/home/codebind/sample_dir
orsample_dir
in present working directory.[email protected]:~$ tar -cvf sample_dir.tar sample_dir sample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output [email protected]:~$ ls sample_dir sample_dir.tar
Here’s what those flags (-cvf) actually mean
-c, --create
– create a new archive
-x, --extract, --get
– extract files from an archive
-f, --file ARCHIVE
– use archive file or device ARCHIVECreate
tar.gz
ortgz
Archive File by Compressing an Directory or a Single FileThe terminal command below will create a
.tar.gz
file calledsample_dir.tar.gz
with a directory/home/codebind/sample_dir
orsample_dir
in present working directory.Notice that we have added extra flag -z to the command.Here’s what the flag -z actually mean
-z, --gzip, --gunzip --ungzip
– Compress the archive with gzip[email protected]:~$ tar -cvzf sample_dir.tar.gz sample_dirsample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output [email protected]:~$ ls sample_dir sample_dir.tar.gz
The command bellow will create a .tgz file. One this to notice is tar.gz and tgz both are similar.
[email protected]:~$ tar -cvzf sample_dir.tgz sample_dirsample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output [email protected]:~$ ls sample_dir sample_dir.tgz
Compressing Multiple Directories or Files at Once
Let’s say, For example we want to compress the
sample_dir
directory, thejava_test
directory, and theabc.py
file to a tar file calledsample_dir.tar.gz
.Run the following command to achieve the goal above.
[email protected]:~$ tar -cvzf sample_dir.tar.gz sample_dir java_test abc.py sample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output java_test/ java_test/HelloCV.java abc.py [email protected]:~$ ls sample_dir java_test abc.py sample_dir.tar.gz
Create
.bzip2
Archive File by Compressing an Directory or a Single File[email protected]:~$ tar -cjvf sample_dir.tar.bz2 sample_dir sample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output [email protected]:~$
Notice that we have added extra flag
-f
to the command.Here’s what the flag-f
actually mean
-f, --file ARCHIVE
– use archive file or device ARCHIVEExtract
.tar
Archive FileWe can extract or untar the compressed file using the tar command. The command below will extract the contents of
sample_dir.tar
to the present directory.[email protected]:~$ tar -xvf sample_dir.tar sample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output [email protected]:~$
The following command will extract or Untar files in specified Directory i.e.
/home/codebind/dir_name
in this case.[email protected]:~$ tar -xvf sample_dir.tar -C /home/codebind/dir_name sample_dir/ sample_dir/main.cpp sample_dir/sample.png sample_dir/output [email protected]:~$
we have added extra flag
-C
to the command.Here’s what the flag-C
actually mean
-C, --directory DIR
– change to directory DIR
