手順
- インストール
- 使ってみる
1. インストール
sudo apt install -y xsel
1-1. バージョン確認
$ xsel --version xsel version 1.2.0 by Conrad Parker <conrad@vergenet.net>
1-2. help
$ xsel --help Usage: xsel [options] Manipulate the X selection. By default the current selection is output and not modified if both standard input and standard output are terminals (ttys). Otherwise, the current selection is output if standard output is not a terminal (tty), and the selection is set from standard input if standard input is not a terminal (tty). If any input or output options are given then the program behaves only in the requested mode. If both input and output is required then the previous selection is output before being replaced by the contents of standard input. Input options -a, --append Append standard input to the selection -f, --follow Append to selection as standard input grows -i, --input Read standard input into the selection Output options -o, --output Write the selection to standard output Action options -c, --clear Clear the selection -d, --delete Request that the selection be cleared and that the application owning it delete its contents Selection options -p, --primary Operate on the PRIMARY selection (default) -s, --secondary Operate on the SECONDARY selection -b, --clipboard Operate on the CLIPBOARD selection -k, --keep Do not modify the selections, but make the PRIMARY and SECONDARY selections persist even after the programs they were selected in exit. -x, --exchange Exchange the PRIMARY and SECONDARY selections X options --display displayname Specify the connection to the X server -t ms, --selectionTimeout ms Specify the timeout in milliseconds within which the selection must be retrieved. A value of 0 (zero) specifies no timeout (default) Miscellaneous options -l, --logfile Specify file to log errors to when detached. -n, --nodetach Do not detach from the controlling terminal. Without this option, xsel will fork to become a background process in input, exchange and keep modes. -h, --help Display this help and exit -v, --verbose Print informative messages --version Output version information and exit Please report bugs to <conrad@vergenet.net>.
1-2-1. key help
$ xdotool key --help Usage: key [options] <keysequence> [keysequence ...] --clearmodifiers - clear active keyboard modifiers during keystrokes --delay DELAY - Use DELAY milliseconds between keystrokes --repeat TIMES - How many times to repeat the key sequence --repeat-delay DELAY - DELAY milliseconds between repetitions --window WINDOW - send keystrokes to a specific window Each keysequence can be any number of modifiers and keys, separated by plus (+) For example: alt+r Any letter or key symbol such as Shift_L, Return, Dollar, a, space are valid, including those not currently available on your keyboard. If no window is given, and there are windows in the stack, %1 is used. Otherwise the currently-focused window is used This command consumes all arguments after it, so you cannot chain additional commands after it.
2. 使ってみる
2-1. 記憶領域
2-1-1. clipboard
$ echo "コピーしたい文字列。" | xsel -bi $ xsel -bo コピーしたい文字列。
クリップボードにコピーしたい文字列。がセットされた。テキストエディタなどでCtrl+Pキーでペーストするとコピーしたい文字列。が貼り付けられるはず。
2-1-2. primary
クリップボードのデータはclipboard以外にもprimary, secondaryという仮想領域に保存することもできる。
$ echo "プライマリ・セレクション" | xsel -i $ xsel -o プライマリ・セレクション
$ echo "プライマリ・セレクション" | xsel -pi $ xsel -po プライマリ・セレクション
2-1-3. secondary
$ echo "セカンダリ・セレクション" | xsel -si $ xsel -so セカンダリ・セレクション
全部使ってみる。
echo "username1" | xsel -pi echo "password1" | xsel -si echo "clip" | xsel -bi xsel -po xsel -so xsel -bo
プライマリにusername1、セカンダリにpassword1、クリップボードにclipを代入した。テキストエディタなどでCtrl+Pするとclipがペーストされるはず。
2-2. クリア
xsel -pc xsel -sc xsel -bc
2-2. 追記
echo "クリップ" | xsel -ba xsel -bo echo "ボード" | xsel -ba xsel -bo
追記する。区切り文字は改行コード。
2-3. 応用
現在日時をクリップボードにセットする。
date "+%Y-%m-%d %H:%M:%S" | xsel -bi xsel -bo
