Event Details

Show & Tell Linux on the Desktop

  • Hosted by Spencer Krum
  • From Minnesota Linux Desktop User Group

Our first meetup in a while! 2019 Year of Linux on the Desktop!

We’ll do show-and-tell style ‘what can you do with Linux’ as well as tips and tricks for Linux on the Desktop. I’m working on locking in a more formal presentation but haven’t confirmed it yet!

Linux Tricks

We talked about a number of tricks, but not all were recorded

# Disable shell history from being saved
unset HISTFILE

# Problem 1: Remove execute capability from file which removes most obvious way
# to change execute bit on file.
sudo chmod -x "$(which chmod)"

# Solution 1: Use 'install' to set mode properties
sudo install -m 755 -T '/bin/chmod' '/tmp/chmod'
sudo /tmp/chmod +x '/bin/chmod'

Zsh features

  • interactive multiline history
  • RPrompt - prompt on right hand side
  • Live colorization - actively updates text colors based on text patterns
  • zmodlod - loads plugins
