Tar
Create a tar file :
tar -cpf target.tar source_folder/
Create a tar.gz file :
tar -cpzf target.tar.gz source_folder/
Create a tar.bz file :
tar -cpjf target.tar.bz2 source_folder/
-c : create -p : preserve permissions -z : gzip -j : bzip -f : file -x : extract -v : verbose -t : test
Extract foo.tar :
tar -xvf foo.tar
Extract gzipped foo.tar.gz :
tar -xvzf foo.tar.gz
Extract bzipped foo.tar.bz2 after changing directory (must exist) to bar :
tar -xvjf foo.tar.bz2 -C bar/
Extract the file blah.txt from foo.tar.bz2 :
tar -xvzf foo.tar.gz blah.txt
Test extraction :
tar -tvzf foo.tar.gz
gzip
Extract file :
gzip -d file.gz
Compress file :
gzip file
Getting info from the zip file :
gzip -l foo.tar.gz compressed uncompressed ratio uncompressed_name 176 10240 98.5% foo.tar
bzip
Same as gzip
Best compression :
bzip2 -9 file
