Get your local IP regardless of your network interface

Shows only IP-addresses of ifconfig except 127.0.0.0/8. I fixed the script to work on more systems and configs short info /inet/!d; #grep inet /127.0/d; # grep -v 127.0 /dr:\s/d; # grep -v dr: s/^.*:$.*$B.*$/\1/ # remove everything exept between : and B

Duplicate a directory tree using tar and pipes

the f is for file and - stdout, This way little shorter. I Like copy-directory function It does the job but looks like SH**, and this doesn't understand folders with whitespaces and can only handle full path, but otherwise fine, function copy-directory () { ; FrDir="$(echo $1 | sed 's:/: :g' | awk '/ / {print $NF}')" ; SiZe="$(du -sb $1 | awk '{print $1}')" ; (cd $1 ; cd .. ; tar c $FrDir/ )|pv -s $SiZe|(cd $2 ; tar x ) ; } Show Sample Output
