How to display the updated files within the specific period of date by "ls" command on Linux terminal

Note that your environment may differ from my environment(lubuntu). For example, if you want to find the updated files from Aug 15 to Aug 20 in 2024, then
1. move to that directory (e.g. "abcde" directory) by "cd" command.

$ cd abcde

2. Execute the next "ls" command.

$ ls -ltr | awk '$6 == "8月" && ($7 >=15 && $7 <= 20) && $8 = 2024 {print $6"-"$7"-"$8,$9}'

If you want to find the updated files before Aug 5 or after Aug 25 in 2024, then
3. execute the next "ls" command.

$ ls -ltr | awk '$6 == "8月" && ($7 <=5 || $7 >= 25) && $8 = 2024 {print $6"-"$7"-"$8,$9}'

How to change brightness of display on Linux terminal

To change brightness of display on Linux terminal,
1. find the display name as follows. That is "DP-2" in my case.

$ xrandr --verbose

2. Execute the following command.

xrandr --output (the display name) --brightness (the number between 0 and 1)

For example,

xrandr --output DP-2 --brightness 0.5

If the last number is close to 0 [1], then the display will be dark [bright].

jumoline.sty

LaTeX文書で複数行にわたって下線を引きたい場合はjumoline.styを使うべし．GitHubにソースもある(https://github.com/kmuto/pandoc2review/blob/main/samples/reviewsample/sty/jumoline.sty)し，ダウンロードもできる．これをスタイルファイルの入ったディレクトリへコピーしてコマンドmktexlsrを実行する．以下はホームディレクトリ~にjumoline.styがあった場合のdebian 12の例．

$ sudo cp -i ~/jumoline.sty /usr/share/texlive/texmf-di
st/tex/latex/tools/
$ sudo mktexlsr

これでプリアンブルに

\usepackage{jumoline}

を追記すれば，地の文で

\Underline{下線を引く．下線を引く．下線を引く．下線を引く．
下線を引く．下線を引く．下線を引く．下線を引く．下線を引く．
下線を引く．下線を引く．下線を引く．下線を引く．下線を引く．
下線を引く．下線を引く．}

としても，複数行にまたがった下線が引かれる．

2024.9.22追記：\Underline{}内に数式モードが含まれるとエラーが発生するようだ．
