Command line nuts

Why on Earth the terminal!?

Slow computer
Snail IO and Apple Mail atrociously slow

Tried to avoid GUI as much as possible
Started living in terminal

Warnings

You will "waste" a lot of time setting this up
Forget (obvious) ROI

More fluid in your workflow
It’s a lot of fun!

Tig

"Graphical" UI for Git history and commits
Awesome for surgical commit edits

Backups

rsync is awwwwwsommmmmmme
Forget all other tools
Of course my backups are scripted

You can do time machine like feature

rsync --archive --verbose --one-file-system --hard-links \
    --human-readable --inplace --numeric-ids -F \
    --link-dest="backup/last" "source" "backup/timestamp"

Command line all in

Mutt

Write emails in vim
Truly offline: mutt reads the local copy synced by offlineimap
offlineimap syncs every 10 mins
msmtpq queues sent email until there is network

Invest in your fluidity even at sunken cost
You will feel faster and happier
