In a production environment, sometimes there is a need to view the contents of the jar online.
At this point, the unzip/tar commands have lost their use.
If the file fileJar.jar
#cd /tmp #touch abc #cd abc #jar -xvf fileJar.jar
Note: Unzip to The current directory will not create a new folder, but will extract all the contents of the jar package to the current folder. Therefore, it is best to create a new directory first
1. Decompress jar package
(1) Decompress jar
Extract to the current directory : jar -xvf hello-0.0.1.jar
If you want to specify the directory, go directly to the target directory to decompress:
jar -xvf ../hello-0.0.1.jar
If you want to specify the directory, you can also use unzip -d to specify the directory
unzip derby.war -d ./gg/ff/
(2) Compressed jar
jar -cvf test.jar ./gg jar -cvfM0 test.jar ./gg
(3) Partial parameter description
Instructions:
-c Create war package
-v Display process information
-f Specify the JAR file name, usually this parameter is required
-M does not generate a list of all items (MANIFEST) file, this parameter will ignore the -m parameter
-0 This is an Arabic numeral, which means only packaging but not compression
2. Decompress the war package
(1) Decompress the war
with the same jar package command
(2) Compressed jar
is the same as compressed jar package
jar -cvf test.war ./gg jar -cvfM0 test.war ./gg
3. Decompress tar package
(1) Decompress tar
Decompress the current The tar package in the directory to the current directory:
tar -zxvf redis-6.0.16.tar.gz ./
Decompress the tar package in the specified directory to the current directory
Command: tar -zxvf The tar file in the specified directory
tar -zxvf ../../softWare/apache-zookeeper-3.6.3-bin.tar.gz
Decompress the tar file in the current directory to the specified directory:
Command: tar -zxvf file name.tgz -C Specify the directory
tar -zxvf redis-6.0.16.tar.gz -C ../install
If you decompress the .tar file
直接 tar -xvf XXX.tar
( 2) Compress tar
Command: tar -zcvf Compressed file name.tar.gz Compressed file name
tar -zcvf test01.tar.gz ./test
4. Decompress the zip file
(1) Compress zip file
Compress the contents of the susu folder in the current directory to test1.zip
zip -r test1.zip ./susu
Compress the susu folder and liu folder in the current directory The content under is compressed into test2.zip
zip -r test2.zip susu liu
(2) Decompress the zip file
Extract test1.zip in the current directory to the current directory
unzip test1.zip
Extract the .zip files starting with test such as test1.zip and test2.zip in the current directory to the current directory at the same time
1) Use the command (note that quotation marks " " are required):
If you don’t add quotes, an error will be reported: Caution: filename not matched: test2.zip
unzip "test*.zip"
2) Use the command (without adding quotes)
unzip test\*.zip
3) Use the command (without adding quotes) Quotation marks)
ls test*.zip | xargs -n1 unzip -o
Extract all .zip files in the current directory to the current directory at the same time
1) Unzip all .zip files in the directory
unzip \*.zip
