In Linux, the commonly used file compression tools are gzip, bzip2, zip. BZIP2 is the ideal compression tool that provides maximum compression. Zip compatibility good windows also supports
1.BZIP2 command
At the shell prompt, enter the command: Zip file:bzip2 filename //file will be compressed and saved as filename.bz2 extract file:bunzip2 filename.bz2 //filename.bz2 will be deleted, and filename instead of bzip2 filename.bz2 file1 file2 file3/usr/work/school //compress the contents of the File1, File2, File3, and/usr/work/school directories and put them in filename.bz2
2.gzip command (same as zip command)
command in Shell prompt: Zip file:gzip filename //file will be compressed and saved as filename.gz extract file:gunzip filename.gz // Filename.gz will be deleted, and the filename instead of gzip-r filename.gz file1 file2 file3/usr/work/school //above command file1, File2, The contents of the File3 and/usr/work/school directories are compressed into filename.gz.
The 3.tar command was originally used for tape backup, but because of the larger size of the hard disk, now the main use of this command to back up all the files
Tar this command packs a large number of files and directories into a file-C to create a new archive-F when used with the-c option, the tar file that is created uses the file name specified by this option, and when used with the-X option, the archive-t specified by this option is released to display the list of files included in the tar file -V Show file Progress-X Extract files from archive-Z use gzip to compress tar files-j use bzip2 to compress tar files to create a tar file:TAR-CVF Filename.tar directory/file/home/mineThe above command puts Directory/file,/home/mine into the archive file to list the contents of the tar file:TAR-TVF Filename.tarTo extract the tar file command, enter the command:TAR-XVF Filename.tarThis command does not delete the tar file, but it copies the contents of the archive to the current directory and preserves any directory structure used by the archive file. Keep in mind that tar does not compress files by default.
To create a file that uses tar and bzip2 to archive compressed files, use the-J option:tar-cjvf filename.tbz FileIf you use the BUNZIP2 command to extract the Filename.tbz file, the FILENAME.TBZ is deleted and replaced with Filename.tar. To extend and de-archive the Bzip.tar file, enter the command:TAR-XJVF filename.tbzTo create a file that is archived and compressed in tar and gzip, use the-Z option:tar-czvf filename.tgz FileIf you use the Gunzip command to extract the Filename.tgz file, filename.tgz will be deleted to Filename.tar instead
