Interesting one-liners

  • Find all drives and ignore loop devices
root@kvm03:/var/log# lsblk | grep -v "loop\|NAME" | grep "^[a-z]\|^[A-Z]" | awk '{print $1}'
sda
sdb
root@kvm03:/var/log# 
root@kvm03:/var/log# lsblk | grep disk | awk '{print $1}'
sda
sdb
root@kvm03:/var/log# 

Continue match until match is found

  • This is using awk, and seems quite powerful as a tool
  • found this little gem at Stack Exchange
awk '/Word A/,/Word D/' filename

/From/CONTINUE/Until/
  • Remove non-english directories
  • change the type to f if you are looking for non-english files
  • ALWAYS test find results before deleting, duh!
sudo find . -type d -not -name "[a-zA-Z0-9]*" -exec rm -rf {} \;
