To extract files from a tar archive on a Linux system, you can use the tar command with the -xvf options as follows:
tar -xvf archive.tar
This will extract the files from the archive.tar file and place them in the current directory. The -x option tells tar to extract the files, the -v option enables verbose output, and the -f option specifies the name of the archive file.
You can also use the -C option to specify the directory where the files should be extracted:
tar -xvf archive.tar -C /path/to/extract/directory
This will extract the files from the archive.tar file and place them in the /path/to/extract/directory directory.
If the tar archive is compressed using gzip (.tar.gz), you can use the -z option to decompress the archive before extracting the files:
tar -zxvf archive.tar.gz
This will extract the files from the archive.tar.gz file and place them in the current directory.
Note: These examples assume that you have permission to access the files and directories specified. You may need to use sudo to run the tar command with root privileges.
By using the tar command, you can easily extract files from a tar archive on a Linux system.
