Compression

In the ancient times, when I was coding mostly in Pascal – size did matter. People were using RAR to shave couple kilobytes from archives, and having 2mb executable was better then having 4mb executable file. In that beautiful time we used  UPX – I wasn’t aware that this project is still alive, and works nicely with binaries create bo go lang.

Packed 1 file.

We have couple options: pigz  and pbzip2 .

tar -c --use-compress-program=pigz -f my_archive.tar.gz /home/archive 

The other trick useful trick is that you can exclude some directories or files

tar -zcvf my_archive.tar.gz --exclude='cache' --exclude='.git' /home/archive
