Example

compress all files and directories in the test directory

[Email protected] app]# zip -9r test.zip test/

compression of all files and subdirectories in the test directory, except for *.gz files, the compressed files are saved in the current directory

[[E Mail protected] app]# ls-l test Total usage 216 -rw-r--r--. 1 root root    181 November 23 17:07 99.sh -rw-------. 1 root root  11595 November 17:07 messages -rw-r--r--. 1 root root   1149 November 17:07 messages2.gz -rw-r--r--. 1 root root   1202 November 17:07 messages.gz -rw-r--r--. 1 root root 14 3538 November 17:07 shell.txt -rw-r--r--. 1 root root  48218 November 17:07 shell.txt.bz2 [[Email protec Ted] app]# zip-r test3.zip test #没有压缩 *.gz files   adding:test/(stored 0)   adding:test/99.sh (deflated 30%)   adding:test/ Messages (deflated 90%)   Adding:test/shell.txt (deflated 62%)   ADDING:TEST/SHELL.TXT.BZ2 ( Deflated 0)

Use the- d parameter to remove the Test/shell.txt file from the compressed package from the above Test3.zip

[Email protected] app]# zip test3.zip- d test/shell.txt Deleting:test/shell.txt

using the- u parameter, the modified/test/99.sh file is updated to update the changed information into the Test3.zip package

[[email protected] app]# zip- u test3.zip/test/99.sh updating:test/99.sh (deflated 30%)

If you have more files in the test directory, you can update them all to Test3.zip using the following method

[Email protected] app]# zip -ru test3.zip/test/

Extract the Test3.zip compressed files to the/tmp directory, and in the decompression process, such as if the same file will be overwritten directly, do not require user confirmation

[Email protected] app]# unzip - o test3.zip-d/tmp/ [Email protected] test]# pwd /tmp/test [[email protected] test]# ls 99.sh Messages shell.txt.bz2
