20の名前を水に本文見てちと悩んだので、optionを見てコマンドをあてる
スレに変更。
簡単なものから。
-b Number the non-blank output lines, starting at 1.
-e Display non-printing characters (see the -v option), and display
a dollar sign (`$') at the end of each line.
-n Number the output lines, starting at 1.
-s Squeeze multiple adjacent empty lines, causing the output to be
single spaced.
-t Display non-printing characters (see the -v option), and display
tab characters as `^I'.
-u The -u option guarantees that the output is unbuffered.
-v Display non-printing characters so they are visible.
