LinuxのようなUNIXライクのOSを扱う際、大体はCUIでの操作になるだろう。つまり、UNIXのコマンドを使って操作したりすることになる。
今回はLinuxのコマンドライン上から、コマンドのチートシートを参照する『Cheat』というパッケージがあるようなので、それを試してみることにした。
1.インストール
まずは、以下のコマンドを実行し必要なパッケージをインストールする。
Debian/Ubuntu
sudo apt-get install git python-pip
sudo pip install docopt pygments
git clone https://github.com/chrisallenlane/cheat.git
cd cheat
sudo python setup.py installRHEL系
sudo yum install git python-pip
sudo pip install docopt pygments
git clone https://github.com/chrisallenlane/cheat.git
cd cheat
sudo python setup.py install最後に、以下のコマンドを実行する。
wget https://github.com/chrisallenlane/cheat/raw/master/cheat/autocompletion/cheat.bash
sudo cp cheat.bash /etc/bash_completion.d/
2.コマンドの実行
さて、それでは実際にチートシートを見てみよう。
まずは、シートが用意されているコマンドのリストを確認するため「cheat -l」コマンドを実行する。

「cheat <コマンド名>」でシートを参照出来る。
test@test-vm-ubuntu:~$ cheat sed
# To replace all occurrences of "day" with "night" and write to stdout:
sed 's/day/night/g' file.txt
# To replace all occurrences of "day" with "night" within file.txt:
sed -i 's/day/night/g' file.txt
# To replace all occurrences of "day" with "night" on stdin:
echo 'It is daytime' | sed 's/day/night/g'
# To remove leading spaces
sed -i -r 's/^\s+//g' file.txt
# Remove empty lines and print results to stdout:
sed '/^$/d' file.txtその他、「-e」オプションで対象となるコマンドのチートシートを編集出来たりもする。
