Using 7z to create archives is OK, but when you use tar, you preserve all file-specific information such as ownership, perms, etc. If that's important to you, this is a better way to do it.
You set the file/dirname transfer variable, in the end point you set the path destination, this command uses pipe view to show progress, compress the file outut and takes account to change the ssh cipher. Support dirnames with spaces.

Compress files or a directory to xz format. XZ has superior and faster compression than bzip2 in most cases. XZ is superior to 7zip format because it can save file permissions and other metadata data.
compress directory archive with xz compression, if tar doesn't have the -J option (OSX tar doesn't have -J)
use -xcvf to decompress
Command to compress logs
compress(){ # compress [FIle/Folder] [NewFileName].[Suffix] # compress image.jpg pictures.tar.bz2 # compress Document/ folder.rar if [ -f $1 ] || [ -d $1 ]; then case $2 in *.tar.bz2) tar -jcvf $2 $1 ;; *.tar.gz) tar -zcvpf $2 $1 ;; *.tar) tar -cvpf $2 $1 ;; *.zip) zip -r $2 $1 ;; *.rar) rar a -r -rr10 $2 $1 ;; *) echo "don't know how to compres '$1'..." ;; esac else echo "'$1' is not a valid file or folder2" fi }
The function had to be cut down to meet the maximum command length requirements. The full version of the function is:
extract()
{
if [ -f $1 ]; then
case $1 in
*.tar.bz2) tar xvjf $1 ;;
*.tar.gz) tar xvzf $1 ;;
*.bz2) bunzip2 $1 ;;
*.rar) unrar x $1 ;;
*.gz) gunzip $1 ;;
*.tar) tar xvf $1 ;;
*.tbz2) tar xvjf $1 ;;
*.tgz) tar xvzf $1 ;;
*.zip) unzip $1 ;;
*.Z) uncompress $1 ;;
*.7z) 7z x $1 ;;
*) echo "'$1' cannot be extracted via >extract<" ;;
esac
else
echo "'$1' is not a valid file!"
fi
}
Note: This is not my original code. I came across it in a forum somewhere a while ago, and it's been such a useful addition to my .bashrc file, that I thought it worth sharing.
