接下來，就是功能參數了

於是決議著手點竄了Bash的PS1參數

\a     an ASCII bell character (07)
\d     the  date  in  "Weekday  Month  Date" format (e.g.翻譯社 "Tue May 26")
\e     an ASCII escape character (033)
\h     the hostname up to the first `.'
\H     the hostname

     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
\u     the username of the current user
\v     the version of bash (e.g., 2.00)
\V     the  release  of  bash, version + patchlevel   (e.g.翻譯社 2.00.0)
\w     the current working directory
\W     the basename of the current  working  directory
\!     the history number of this command
\#     the command number of this command
\$     if  the effective UID is 0, a #, otherwise a $

nn   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

於是乎，鉦昱翻譯公司將我的PS1變數設置於以下：

#0

還記得本文最上方那張圖嗎？

裡面的內容打上：

若是翻譯公司遇到了跟我一樣的問題

老是要在打一次 bash 這個指令才會更新色彩！！

這代表PS1參數設定不正確，讓Bash沒法准確判讀哪邊是non-printing characters

完成後，你就能夠看到美美的Bash了！

（註：本來這裡括號的體式格局有誤，此刻已更正，也就是除非凡變數之外，都要加上\[ \] ！！）

這時候，只需要在本身的家目次再創立一個 .bash_profile

如許子，每次登入bash就會本身去找bashrc來更新設定檔囉！

另外，還有文字的樣式
