Bash Cut示例

To automate tasks in Bash scripts, you can utilize various commands and programs. While it takes a good understanding of commands to create great Bash scripts, there are some simple commands that beginners can use as well. For example, the "cut" command is a commonly used tool that can be used to extract specific text portions from a file. You can easily use the cut command to process text data by specifying fields and delimiters. In addition, you can also combine other commands and tools, such as grep, awk, etc., to process and manipulate data more efficiently. Mastering the use of these basic commands can help you better utilize Bash scripts to automate various tasks.

Cut is a very flexible command that can be used in conjunction with other commands such as "sort" and "grep". Below are some of the best Bash cut examples through which you can better understand how to use the “cut” command.

Bash Cut Example

The "cut" command is very convenient when extracting data from text files. Just specify the fields you need and the command will handle the rest. You can use the following command to use it:

Cut-d ‘separator’-f1 file.txt

  1. The "-d" option allows us to enter wildcard characters. It is a character or series of characters that separates text strings. Replace "unqualified" with the actual "unqualified".
  2. Use the "-f" option to specify which fields (column numbers) to extract from the file.

Let us take an "info.txt" file as an example, which contains the following information set:

Pilates, Fiji, 26 years old

India Sean, 21 years old

2. Joshua, Japan, 19 years old

Now, to extract the first and third files from this file, the command will be:

cut—d’,’—f1,3 info.txt

If the data in the file is tab-delimited, the value of its delimiter will be "$'t'".

If you need to get a series of characters from the corresponding field, please use the "-c" option:

cut—c1—5 file.txt

Please note that the "-c" option is not combined with other options. When executed, it displays output based on the given character range.

in conclusion

In Linux, “Cut” is an important tool that you can use to extract data from different files. Although simple, it has many uses and can be combined with many commands. This quick guide discusses some examples of Bash Cut commands. First, we explain the basic commands and then discuss some advanced examples.
