How to solve the problem of garbled characters displayed on the Linux command line

In the Linux operating system, sometimes we encounter garbled characters when using the command line interface. This will affect our normal viewing and understanding of command output results or file contents. The causes of garbled characters may be due to incorrect system character set settings, terminal software not supporting the display of specific character sets, inconsistent file encoding formats, etc. This article will introduce some methods to solve the problem of garbled characters displayed on the Linux command line, and provide specific code examples to help readers solve similar problems.

1. Check the system character set settings

The character set settings of the Linux system are usually stored in the environment variable LANG. You can view the current character set settings through the following command:

echo $LANG

If the displayed result is garbled or incorrect character set, you can set the correct character set by modifying the configuration file. Modify the ~/.bashrc or /etc/profile file and add the following line in it:

export LANG=zh_CN.UTF-8

Then execute the following command to make the modification effective:

source ~/.bashrc

2. Modify the terminal software character set

Some terminal software may not support the display of certain character sets, resulting in garbled characters. You can try to modify the character set settings of the terminal software and set it to UTF-8 encoding. Taking gnome-terminal as an example, you can set it up through the following steps:

Open gnome-terminal, click the "Edit" option in the upper left corner of the interface, select "Preferences", and select "Text" in the opened dialog box ” tab, set “Character Encoding” to “Unicode (UTF-8)”.

3. Modify the file encoding format

In the Linux system, sometimes we will encounter files with different encoding formats. If the file encoding format is inconsistent with the system character set, it will also This will cause garbled characters to be displayed. You can use tools such as iconv to convert encoding formats. Take converting a GBK-encoded file to UTF-8 as an example, execute the following command:

iconv -f gbk -t utf-8 input.txt > output.txt

This will The input.txt file is converted from GBK encoding to UTF-8 encoding and output to the output.txt file.

Through the above methods, we can effectively solve the problem of garbled characters displayed on the Linux command line. In actual use, you can choose the appropriate method to solve the garbled problem according to the specific situation to ensure the smooth progress of command line operations.
