- Creating zip
| Zipping of files | zip backup.zip file1 file2 file3 | creates a zip containing the 3 files |
| Delete the original file after zip | zip -m mybackup.zip file1 | Removes file1 after zipping it into backup.zip |
| Append a file in zip archive | zip -u mybackup.zip file2 | Adds file2 to an existing zip mybackup.zip |
| Remove a file from a zip file | zip -d mybackup.zip file1 | Removes file1 from mybackup.zip |
| Zipping a Directory recursively | zip -r backupDir.zip dir1/ dir2/ | Zips the directories dir1 and dir2 |
- Unzip commands
| Basic unzip | unzip mybackup.zip | |
| Unzip content in a particular directory | unzip -d /home/directory/ mybackup.zip | Unzips the content into /home/directory/ directory |
| List the contents of the zip file | unzip -l mybackup.zip | lists the content of the zip file without extracting it |
- Gzip command
Compresses single file only. GZIP has a higher compression ration compared to normal zip.
Idea is to tar the required files and then gzip the single tar file.
GZIP removes the original file and creates a “.gz” file.
gzip myFile.txt | creates a myFile.txt.gz file and the original myFile.txt gets deleted. |
| gunzip myFile.txt.gz | extracts the original file myFile.txt and myFile.txt.gz file gets removed. |
- Tar command
Stands for Tape Archive used for creating or extracting Archive files. Archive files are used to collect multiple data files together into single file for easier portability & storage.
| Create a tar archive | tar -cvf arch.tar *.java | creates a “arch.tar” archive file containing all the “.java” files present in the directory. -c : Creates archive -v : Verbose information -f : given filename |
| Update existing tar file | tar -rvf arch.tar *.html | adds all the “.html” files into existing tar “arch.tar” |
| Extract tar file | tar -xvf arch.tar | extracts the content of “arch.tar” into the current directory. -x : Extract the archive |
| Extract tar file in specific directory | tar -xvf arch.tar -C /home/directory/ | Extracts the content of the tar into directory “/home/directory/” |
| List tar content without extraction | tar -tvf arch.tar | Lists the entire content of the “arch.tar” file |
