Working with a brainless mass

To maintain, and get a feel for where things are clone the repository and list the contents using:

$ tree -L [n]

where [n] is the depth we are willing to traverse through this mess. However! Since this is a work in progress, cloning directly from the repository will also clone the other gitbooks that I'm working: this means that folder structure is not preserved and working offline requires downloading the whole thing as well as all the other shit I'm working on in these gitbooks. 

mv -fileName1 +fileName2
mv: illegal option -- N
usage: mv [-f | -i | -n] [-v] source target
       mv [-f | -i | -n] [-v] source ... directory

Tmux customization vs screen

# 1. redo last command but as root sudo !! # 2. open an editor to run a command ctrl+x+e # 3. create a super fast ram disk mkdir -p /mnt/ram mount -t tmpfs tmpfs /mnt/ram -o size=8192M # 4. don't add command to history (note the leading space) ls -l # 5. fix a really long command that you messed up fc # 6. tunnel with ssh (local port 3337 -> remote host's 127.0.0.1 on port 6379) ssh -L 3337:127.0.0.1:6379 root@emkc.org -N # 7. quickly create folders mkdir -p folder/{sub1,sub2}/{sub1,sub2,sub3} # 8. 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
