Aug 08, 2024 am 01:37 AMWhen the Linux command line displays garbled characters, you can try to set the character encoding to UTF-8. It can be set via the following commands:,,"bash,exportLC_ALL=en_US.UTF-8,exportLANG=en_US.UTF-8,"
In Linux systems, garbled characters displayed on the command line are a common problem. This is usually caused by incorrect character encoding settings. This article will introduce in detail how to solve the problem of garbled characters displayed on the Linux command line.
1. Understand character encoding
Before solving this problem, we need to understand the basic concept of character encoding. Character encoding is a method of encoding the correspondence between characters (such as letters, numbers, and punctuation marks) and two's complement numbers (0 and 1). Different character encoding schemes have different two's complement representation methods. If the character encoding settings are incorrect, the command line may display garbled characters.
2. Detect system language and character set
We need to detect the language and character set settings of the system. In Linux systems, you can view the language and character set settings of the system through the following commands:
locale
This command will display the current language, region and character set settings of the system. The output may be similar to:
LANG=en_US.UTF-8 LANGUAGE=en_US:en LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL=
From the output results, we can see that the system's character set is set to en_US.UTF-8linux command line Chinese garbled characters, which means that the system uses UTF-8 encoding by default to process text data.
3. Change the terminal’s character encoding settings
If the command line displays garbled characters, it may be because the terminal’s character encoding settings are incorrect. We can change the terminal’s character encoding settings in the following ways:
3.1 Change the character encoding settings of Vim editor
Vim is a commonly used text editor. We can change its character encoding settings to prevent the command line from displaying garbled characters. In Vim, you can view and change the character encoding settings through the following commands:
:set fileencodings=utf-8,gbk,gb18030,gb2312,big5,euc-jp,euc-kr,hz,iso-2022-jp,iso-2022-kr,shift-jis,latin1,cp949,macce,ibm850,ibm866,ibm869,ibm874,ibm037,ibm047,ibm100,ibm1047,ibm1127,ibm1147,ibm1251,ibm1252,ibm737,ibm775,ibm855,ibm857,ibm001,ibm002,ibm005,ibm010,ibm013,ibm0134,ibm0137,ibm273,ibm277,ibm278,koi8-r,koi8-u,koi8-ru,utf-16le,utf-16be,utf-32le,utf-32be,utf-7,binary,base64,hex :set encoding=utf-8
3.2 Change Xshell’s character encoding settings
Xshell是一款常用的SSH顧客端,我們可以更改其字符編碼設(shè)置來(lái)防止命令行顯示亂碼,在Xshell中,可以通過(guò)以下步驟更改字符編碼設(shè)置:
1、打開(kāi)Xshell,點(diǎn)擊“文件”菜單,選擇“屬性”。
2、在彈出的“屬性”窗口中,選擇“終端”選項(xiàng)卡。
3、在“終端”選項(xiàng)卡中,找到“字符編碼”下拉框,選擇正確的字符編碼(如UTF-8)。
4、點(diǎn)擊“確定”按鈕,保存設(shè)置。
4.重啟系統(tǒng)和應(yīng)用
更改完終端的字符編碼設(shè)置后,須要重啟系統(tǒng)和應(yīng)用以使設(shè)置生效,在Linux系統(tǒng)中,可以通過(guò)以下命令重啟系統(tǒng):
sudo reboot
對(duì)于其他應(yīng)用,如Vim、Xshell等,一般可以通過(guò)關(guān)掉并重新打開(kāi)應(yīng)拿來(lái)使設(shè)置生效。
相關(guān)問(wèn)題與解答:
問(wèn)題1:怎么查看系統(tǒng)的字符集設(shè)置?
答:可以通過(guò)運(yùn)行l(wèi)ocale命令查看系統(tǒng)的字符集設(shè)置linux操作系統(tǒng)原理,輸出結(jié)果中的LANG變量表示系統(tǒng)的字符集設(shè)置。
問(wèn)題2:怎么更改Vim編輯器的字符編碼設(shè)置?
答:在Vim中,可以通過(guò)運(yùn)行:setfileencodings命令查看和更改文件的字符編碼設(shè)置,通過(guò)運(yùn)行:setencoding命令可以更改當(dāng)前緩沖區(qū)的字符編碼設(shè)置linux命令行中文亂碼,要使設(shè)置永久生效linux計(jì)劃任務(wù),可以將這兩個(gè)命令添加到Vim的配置文件(如~/.vimrc)中。
