Capability description: Compress one or more files
-
Usage: zip [options] compressed file name.zip FILE...
option Effect -r Recursive compression of files and subdirectories under a directory -d Delete the specified file from the compressed file -q Do not show command execution when compressing -x Exclude some files from compression without compression
Example: Copy/var/log/messages to/tmp/compress directory and compress messages files.
[root@node1 ~]# cd /tmp/ && mkdir compress [root@node1 tmp]# cd compress [root@node1 compress]# cp /var/log/messages ./ [root@node1 compress]# ll -h total 44K -rw------- 1 root root 42K Feb 25 14:38 messages [root@node1 compress]# zip messages.zip messages adding: messages (deflated 94%) [root@node1 compress]# ll -h total 48K -rw------- 1 root root 42K Feb 25 14:38 messages -rw-r--r-- 1 root root 2.9K Feb 25 14:39 messages.zip
Description: zip is followed by the target file name, which is the compressed custom compressed package name, then the file or directory to be compressed.
Example: Copy all directories and files under /var/log to the / tmp directory and use zip for archiving.
[root@node1 compress]# cp -r /var/log/ /tmp/ [root@node1 compress]# du -sh /tmp/log/ 3.9M /tmp/log/ [root@node1 compress]# cd .. [root@node1 tmp]# zip -r -q log.zip log/ [root@node1 tmp]# ll -h total 416K drwxr-xr-x 2 root root 42 Feb 25 14:39 compress drwxr-xr-x 8 root root 4.0K Feb 25 14:40 log -rw-r--r-- 1 root root 411K Feb 25 14:42 log.zip
Example: Generate a file of 1..10.txt without compressing 10.txt.
[root@node1 tmp]# mkdir test [root@node1 tmp]# cd test/ [root@node1 test]# for i in .txt;do touch $i;done [root@node1 test]# ls 10.txt 1.txt 2.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt 9.txt [root@node1 test]# zip text.zip *.txt -x 10.txt adding: 1.txt (stored 0%) adding: 2.txt (stored 0%) adding: 3.txt (stored 0%) adding: 4.txt (stored 0%) adding: 5.txt (stored 0%) adding: 6.txt (stored 0%) adding: 7.txt (stored 0%) adding: 8.txt (stored 0%) adding: 9.txt (stored 0%)
