Power 10 Linux Commands

  1. redo last command but as root

sudo !!

  1. open an editor to run a command


  1. create a super fast ram disk

mkdir -p /mnt/ram
mount -t tmpfs tmpfs /mnt/ram -o size=8192M

  1. don’t add command to history (note the leading space)

    ls -l

  2. fix a really long command that you messed up


  1. tunnel with ssh (local port 3337 -> remote host’s on port 6379)

ssh -L 3337: root@emkc.org -N

  1. quickly create folders

mkdir -p folder/{sub1,sub2}/{sub1,sub2,sub3}

  1. intercept stdout and log to file

cat file | tee -a log | cat > /dev/null

bonus: exit terminal but leave all processes running

disown -a && exit
