通常的情況下、在我們的系統(tǒng)會(huì)保存?zhèn)浞輇ash配置,在/etc/skel/.bashrc這個(gè)位置。我便借助這個(gè)位置保存的備份更改了自己的終端顏色顯示。如下圖所示,是我很喜歡的顯示。
如果各位需要自己的顯示內(nèi)容,完全可以自己配置屬于自己的bash。下面我將我的配置文件粘貼到這里。

在這里我重點(diǎn)說(shuō)一下終端顏色顯示
要修改linux終端命令行顏色,我們需要用到PS1,PS1是Linux終端用戶的一個(gè)環(huán)境變量,用來(lái)說(shuō)明命令行提示符的設(shè)置。在終端輸入命令:#set,即可在輸出中找到關(guān)于PS1的定義如下:
PS1的定義中個(gè)常用的參數(shù)的含義如下:
\d :#代表日期,格式為weekday month date,例如:"Mon Aug 1"
\H :#完整的主機(jī)名稱
\h :#僅取主機(jī)的第一個(gè)名字
\t :#顯示時(shí)間為24小時(shí)格式,如:HH:MM:SS
\T :#顯示時(shí)間為12小時(shí)格式
\A :#顯示時(shí)間為24小時(shí)格式:HH:MM
\u :#當(dāng)前用戶的賬號(hào)名稱
\v :#BASH的版本信息
\w :#完整的工作目錄名稱
\W :#利用basename取得工作目錄名稱,所以只會(huì)列出最后一個(gè)目錄
\# :#下達(dá)的第幾個(gè)命令
\$ :#提示字符,如果是root時(shí),提示符為:# ,普通用戶則為:$
由此,我們可知linux默認(rèn)的命令行提示信息為:[當(dāng)前用戶的賬號(hào)名稱@主機(jī)的第一個(gè)名字 工作目錄的最后一項(xiàng)]#
2.顏色的設(shè)置
F B
30 40 黑色
31 41 紅色
32 42 綠色
33 43 黃色
34 44 藍(lán)色
35 45 紫紅色
36 46 青藍(lán)色
37 47 白色
根據(jù)顏色表,套用入字符顏色設(shè)置格式中,就可以對(duì)linux終端命令行顏色進(jìn)行個(gè)性化設(shè)置了。
3.修改.bashrc文件
通過(guò)上面的設(shè)置只能改變當(dāng)前終端的命令行格式,關(guān)閉這個(gè)終端,在重新打開的一個(gè)終端中命令行格式又會(huì)恢復(fù)到默認(rèn)的形式。想要永久性的改變終端命令行格式,需要修改.bashrc文件。
在.bashrc文件中對(duì)PS1的內(nèi)容進(jìn)行更改就可以做到終端顯示了
PS1='${debian_chroot:+($debian_chroot)}\[\033[36;40m\]\u \[\033[1;31;40m\]\W \[\033[1;35;40m\]\$ > \[\033[1;0;0m\]:這是我的配置,希望你能夠喜歡。
同時(shí),這個(gè)文件默認(rèn)在~/.bashrc,打開進(jìn)行復(fù)制粘貼就可以。最后將一張完整的終端圖像貼到這里。希望你能夠喜歡我這份bash配置。
