Basic Settings in .bashrc

# Unable Built-in Keyboard and Touchpad
# Use "xinput list" to see the device name to disable
# xinput set-int-prop "FSPPS/2 Sentelic FingerSensingPad" "Device Enabled" 8 0

xinput set-int-prop "AT Translated Set 2 keyboard" "Device Enabled" 8 0

# History configurations
# Ingore repeated commands
export HISTCONTROL=ignoredups
# Ingore command in the string devided by colon
export HISTIGNORE="ls:cd:exit"
export HISTFILESIZE=10000000
export HISTSIZE=100000
# Make commands appended
shopt -s histappend
# Append commands real time
PROMPT_COMMAND="history -a; $PROMPT_COMMAND"

AutoJump - an efficient alternative of cd

AutoJump 会记住 cd 命令并用 j 来进入所有的目录。更重要的是 AutoJump 可以模糊匹配。意味着只需要提供一个字母,就可以匹配到之前访问过的该首字母的目录。

j d -> cd ~/Development

j t -> cd ~/Development/Tomcat 1.3

高级功能

  • jc(注意没空格 不是上面的 j c)仅在子目录下跳转,非常适合寻找被嵌套的 log
  • jo 会在操作系统下打开匹配的目录。
  • j -i 增加当前目录权重
  • j -d 减少当前目录权重
  • j –purge 消除所有的权重

Cloc - Code Statistics

Glances - An alternative of top

Nmon - Performance Monitor

Seahorse - Password Management

Usage: https://www.linux.com/learn/manage-passwords-encryption-keys-and-more-seahorse

tldr - Quick Examples for linux Tools

Cheat - Quick Tutorial for Linux Tools

Use cheat instruction to look for command usage instead of MAN: https://github.com/chrisallenlane/cheat.

Usage:

  cheat <cheatsheet>      :Open the cheatsheet of <cheatsheet>
  cheat -e <cheatsheet>   :Edit cheatsheet
  cheat -s <keyword>      :Search cheatsheets for <keyword>
  cheat -l                :List cheatsheets
  cheat -d                :List directories on CHEATPATH

i3wm - Windows Management

Version: 4.15.0.1-323-gccb19472 (2018-09-28, branch “gaps-next”)

Official website: https://i3wm.org/

Install i3wm

sudo apt-get install i3

Install themes

Installing themes will rewrite the config file.

Official Website: https://github.com/unix121/i3wm-themer

$mod+d will launch Rofi after applying this theme.

git clone https://github.com/unix121/i3wm-themer
cd i3wm-themer/
sudo pip install -r requirements.txt

# For Arch, ArchLabs or Manjaro Linux
# (Should work for other Arch-based distros as well)
./install_requirements_arch.sh
# or
./install_arch.sh

# For Debian
./install_debian.sh

# For Ubuntu
./install_ubuntu.sh

Copy the script in the scripts folder to your polybar directory:

cp -r scripts/* /home/$USER/.config/polybar/

Install the config files located in the src/defaults/ directory (not 100% required but I suggest you do so just to be sure).

python i3wm-themer.py --config config.yaml --install defaults/

Pick a theme you like from the collection and load it:

python i3wm-themer.py --config config.yaml --load themes/[theme_id].json

Customize i3wm

File path: /home//.config/i3/config
