Week 36 - tar balls (17 March 2003)
by
Adrian Mayo - Senior Editor for Mac OS X Unix
Monday - creating and extracting tar balls
Just as Aladdin Systems' StuffIt allows one to 'stuff' many files into a single '.sit' file, the Unix 'tar' command allows one to create an archive (often called a tar ball). 'tar' was originally used to archive to magnetic tape (tape archiver), but now a days it is more often used to archive to a named file.
To archive the whole of the ~/Sites directory into a single file called sites.tar, use:
cd ~
tar cvf sites.tar Sites
The options 'cvf' do the following:
c - create a new archive
v - verbose, name each file as it is added to the archive
f - archive to a named file, in this case sites.tar
The original directory is untouched.
To decompress the archive use the command:
tar xvf sites.tar
This extracts the original files into a directory called 'Sites', which is created if it does not already exist.
The option 'x' says to extract from existing archive.
