||
| − | |||
| − | このガイドでは''通常ユーザーの個人用プロンプトをカスタマイズ''する方法を紹介します。 |
||
| − | |||
| − | == 変更の適用 == |
||
| − | |||
| − | ([http://mywiki.wooledge.org/SubShell subshell] がない) {{ic|.bashrc}} に加えた変更は次を実行することで適用されます: |
||
| − | $ source ~/.bashrc |
||
| − | |||
| − | == 基本のプロンプト == |
||
| − | |||
| − | 以下の設定は root のプロンプトと root 以外のユーザーを見分けるのに役に立ちます。 |
||
| − | |||
| − | === 通常ユーザー === |
||
| − | |||
| − | ''通常ユーザー''の緑のプロンプト: |
||
| − | |||
| − | <div style="font-family: monospace; white-space: pre; padding: 1em; border: 3px solid #bcd; background-color: black; color: #aaa;"><span style="color: #0f0">[chiri@zetsubou ~]$</span> <span style="text-decoration: blink;">_</span></div> |
||
| − | {{hc|~/.bashrc| |
||
| − | <nowiki>#PS1='[\u@\h \W]\$ ' # Default |
||
| − | PS1='\[\e[1;32m\][\u@\h \W]\$\[\e[0m\] '</nowiki>}} |
||
| − | |||
| − | === Root === |
||
| − | |||
| − | ''root'' の赤のプロンプト ({{ic|/etc/skel/}} からコピーしてない場合は、コピーしてください): |
||
| − | |||
| − | <div style="font-family: monospace; white-space: pre; padding: 1em; border: 3px solid #bcd; background-color: black; color: #aaa;"><span style="color: #f00">[root@zetsubou ~]#</span> <span style="text-decoration: blink;">_</span></div> |
||
| − | {{hc|/root/.bashrc| |
||
| − | <nowiki>#PS1='[\u@\h \W]\$ ' # Default |
||
| − | PS1='\[\e[1;31m\][\u@\h \W]\$\[\e[0m\] '</nowiki>}} |
||
| − | |||
| − | == ちょっとだけオシャレなプロンプト == |
||
| − | |||
| − | === 通常ユーザー === |
||
| − | |||
| − | ''通常ユーザー''の緑/青のプロンプト: |
||
| − | |||
| − | <div style="font-family: monospace; white-space: pre; padding: 1em; border: 3px solid #bcd; background-color: black; color: #aaa;"><span style="color: #0a0">chiri</span> <span style="color: #00f">~/docs</span> <span style="color: #0f0">$</span> echo "sample output text"<br />sample output text<br /><span style="color: #0a0">chiri</span> <span style="color: #00f">~/docs</span> <span style="color: #0f0">$</span> <span style="text-decoration: blink;">_</span></div> |
||
| − | {{bc|<nowiki>PS1='\[\e[0;32m\]\u\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[1;32m\]\$\[\e[m\] \[\e[1;37m\]'</nowiki>}} |
||
| − | |||
| − | とても見やすい、明るい白のテキストのコンソールで、カラフルなプロンプトとテーマになります。 |
||
| − | |||
| − | 上の文字列にはカラーセットのエスケープシーケンス ({{ic|\[\e[''color''\]}} で始まり {{ic|\[\e[m\]}} で終わる) と情報のプレースホルダが含まれています: |
||
| − | |||
| − | * '''\u''' - ユーザー名。元のプロンプトにある '''\h''' はホスト名を表示します。 |
||
| − | * '''\w''' - カレントディレクトリの絶対パス。相対パスを表示するには '''\W''' を使います。 |
||
| − | * '''\$''' - プロンプト記号 (例: root の場合 {{ic|#}}、通常ユーザーの場合 {{ic|$}})。 |
||
| − | * '''\[''' と '''\]''' - bash にカーソルを正しく配置する方法を知らせるために、このタグはカラーコードの前後に置きます。 |
||
| − | |||
| − | その他の特殊文字については、gnu.org の [http://www.gnu.org/software/bash/manual/html_node/Printing-a-Prompt.html bash プロンプトのコントロール] のウェブページを見て下さい。 |
||
| − | |||
| − | 最後のカラーセットのシーケンス {{ic|\[\e[1;37m\]}} は閉じられていませんが、これは残りのテキスト (ターミナルに入力されたテキストやプログラムの出力など) が明るい白になるようにするためです。出力を元の色で表示するために、この色を変更したり、最後のエスケープシーケンスを削除することが望ましいでしょう。 |
||
| − | |||
| − | === Root === |
||
| − | |||
| − | ''root'' の赤/青のプロンプト: |
||
| − | |||
| − | <div style="font-family: monospace; white-space: pre; padding: 1em; border: 3px solid #bcd; background-color: black; color: #aaa;"><span style="color: #a00">root</span> <span style="color: #00f">~/docs</span> <span style="color: #a00">#</span> <span style="color: #0a0">echo "sample output text"<br />sample output text<br /></span><span style="color: #a00">root</span> <span style="color: #00f">~/docs</span> <span style="color: #a00">#</span> <span style="color: #0a0"><span style="text-decoration: blink;">_</span></span></div> |
||
| − | {{bc|<nowiki>PS1='\[\e[0;31m\]\u\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[0;31m\]\$ \[\e[m\]\[\e[0;32m\]'</nowiki>}} |
||
| − | |||
| − | 赤色の記号と緑色のコンソールテキストになります。 |
||
| − | |||
| − | == 高度なプロンプト == |
||
| − | |||
| − | === 256色の Load/Mem ステータス === |
||
| − | |||
| − | This is not even pushing the limits. Other than using {{ic|sed}} to parse the memory and load average (using the {{ic|-u}} option for non-buffering), and the builtin ''history'' to save your history to your {{ic|HISTFILE}} after every command, which you may find incredibly useful when dealing with crashing shells or subshells, this is essentially just making BASH print variables it already knows, making this extremely fast compared to prompts with non-builtin commands. |
||
| − | |||
| − | This prompt is from AskApache.com's [http://www.askapache.com/linux-unix/bash-power-prompt.html BASH Power Prompt article], which goes into greater detail. It is especially helpful for those wanting to understand 256 color terminals, ncurses, termcap, and terminfo. |
||
| − | |||
| − | This is for '''256 color terminals''', which is where the {{ic|\033[38;5;22m}} terminal escapes come from. |

| − | |||
| − | === プロンプトの拡張 === |
||
| − | |||
| − | man ページには様々な Bash プロンプトエスケープが載っています: |
||
| − | |||
| − | {{bc|1=Bash allows these prompt strings to be customized by inserting a |
||
| − | number of ''backslash-escaped special characters'' that are |
||
| − | decoded as follows: |
||
| − | |||
| − | \a an ASCII bell character (07) |
||
| − | \d the date in "Weekday Month Date" format (e.g., "Tue May 26") |
||
| − | \D{format} the format is passed to strftime(3) and the result |
||
| − | is inserted into the prompt string an empty format |
||
| − | results in a locale-specific time representation. |
||
| − | The braces are required |
||
| − | \e an ASCII escape character (033) |
||
| − | \h the hostname up to the first `.' |
||
| − | \H the hostname |
||
| − | \j the number of jobs currently managed by the shell |
||
| − | \l the basename of the shell's terminal device name |
||
| − | \n newline |
||
| − | \r carriage return |
||
| − | \s the name of the shell, the basename of $0 (the portion following |
||
| − | the final slash) |
||
| − | \t the current time in 24-hour HH:MM:SS format |
||
| − | \T the current time in 12-hour HH:MM:SS format |
||
| − | \@ the current time in 12-hour am/pm format |
||
| − | \A the current time in 24-hour HH:MM format |
||
| − | \u the username of the current user |
||
| − | \v the version of bash (e.g., 2.00) |
||
| − | \V the release of bash, version + patch level (e.g., 2.00.0) |
||
| − | \w the current working directory, with $HOME abbreviated with a tilde |
||
| − | \W the basename of the current working directory, with $HOME |
||
| − | abbreviated with a tilde |
||
| − | \! the history number of this command |
||
| − | \# the command number of this command |
||
| − | \$ if the effective UID is 0, a #, otherwise a $ |
||
| − | \nnn the character corresponding to the octal number nnn |
||
| − | \\ a backslash |
||
| − | \[ begin a sequence of non-printing characters, which could be used |
||
| − | to embed a terminal control sequence into the prompt |
||
| − | \] end a sequence of non-printing characters |
||
| − | |||
| − | The command number and the history number are usually different: |
||
| − | the history number of a command is its position in the history |
||
| − | list, which may include commands restored from the history file |
||
| − | (see HISTORY below), while the command number is the position in |
||
| − | the sequence of commands executed during the current shell session. |
||
| − | After the string is decoded, it is expanded via parameter |
||
| − | expansion, command substitution, arithmetic expansion, and quote |
||
| − | removal, subject to the value of the promptvars shell option (see |
||
| − | the description of the shopt command under SHELL BUILTIN COMMANDS |
||
| − | below). |
||
| − | }} |
||
| − | |||
| − | === カーソルの位置 === |
||
| − | |||
| − | 以下のシーケンスはカーソルの位置をセットします: |
||
| − | |||
| − | {{bc|<nowiki>\[\033[<row>;<column>f\]</nowiki>}} |
||
| − | |||
| − | 現在のカーソル位置を保存するには: |
||
| − | |||
| − | {{bc|<nowiki>\[\033[s\]</nowiki>}} |
||
| − | |||
| − | 位置を復元するには、以下のシーケンスを使用: |
||
| − | |||
| − | {{bc|<nowiki>\[\033[u\]</nowiki>}} |
||
| − | |||
| − | 下の例は、以上のシーケンスを使って右上のコーナーに時計を表示します: |
||
| − | |||
| − | {{bc|<nowiki>PS1=">\[\033[s\]\[\033[1;\$((COLUMNS-4))f\]\$(date +%H:%M)\[\033[u\]"</nowiki>}} |
||
| − | |||
| − | 環境変数 {{ic|COLUMNS}} にはターミナルの列の数が入ります。上の例では {{ic|COLUMNS}} から ''4'' を引いて {{ic|date}} の5文字分だけ右端に出力できるように整えています。 |
||
| − | |||
| − | === 戻り値を視覚的に表現 === |
||
| − | |||
| − | 以下のプロンプトを使うことで最後に実行したコマンドの返り値をわかりやすくできます: |
||
| − | |||
| − | <div style="font-family: monospace; padding: 1em; border: 3px solid #bcd; background-color: black; color: #fff;">0 <span style="color: green;">;)</span> : true<br />0 <span style="color: green;">;)</span> : false<br />1 <span style="color: red;">;(</span> :</div> |

||
| − | |||
| − | ''Zero'' は緑のスマイリーで ''non-zero'' は赤になります。最後の操作が成功したならばプロンプトは微笑みます。 |
||
| − | |||
| − | 以下のようにユーザー名とホスト名を含めても良いでしょう: |
||
| − | |||
| − | <div style="font-family: monospace; padding: 1em; border: 3px solid #bcd; background-color: black; color: #fff;"><span style="font-weight: bold;">0</span> <span style="color: #0a0; font-weight: bold;">;) andy@alba</span> <span style="color: #55f; font-weight: bold;">~ $</span> true<br /><span style="font-weight: bold;">0</span> <span style="color: #0a0; font-weight: bold;">;) andy@alba</span> <span style="color: #55f; font-weight: bold;">~ $</span> false<br /><span style="font-weight: bold;">1</span> <span style="color: #a00; font-weight: bold;">;(</span> <span style="color: #0a0; font-weight: bold;">andy@alba</span> <span style="color: #55f; font-weight: bold;">~ $</span> <span style="text-decoration: blink;">_</span></div> |
||
| − | |||
| − | {{bc|<nowiki>#return value visualisation |
||
| − | PS1="\[\033[01;37m\]\$? \$(if [[ \$? == 0 ]]; then echo \"\[\033[01;32m\];)\"; else echo \"\[\033[01;31m\];(\"; fi) $(if [[ ${EUID} == 0 ]]; then echo '\[\033[01;31m\]\h'; else echo '\[\033[01;32m\]\u@\h'; fi)\[\033[01;34m\] \w \$\[\033[00m\] "</nowiki>}} |
||
| − | |||
| − | また、宜しければ、''zero'' ステータスのときは <span style="color: #0a0; font-weight: bold;">✓</span> ユニコード記号を、''nonzero'' ステータスのときは <span style="color: #a00; font-weight: bold;">✗</span> ユニコード記号を使ってプロンプトを構築することもできます: |

| − | If you do not reset the text color at the end of your prompt, both the text you enter and the console text will simply stay in that color. If you want to edit text in a special color but still use the default color for command output, you will need to reset the color after you press {{ic|Enter}}, but still before any commands get run. You can do this by installing a DEBUG trap, like this: |
