Today, the editor shares with you how to use linux's fold command to limit file width. I believe many people don't know much about it. In order to make you understand better, I summarized the following contents for you. Let's look down together. I'm sure you'll get something.

The fold command reads the contents from the specified file, adds additional characters to the columns that exceed the column width, and outputs them to the standard output device. If no file name is specified, or if the file name given is "-", the fold instruction reads the data from the standard input device.

Syntax format: fold [parameters] [file]

Common parameters:

-b calculates column widths in Byte instead of line numbers-s uses space characters as break points-w sets the maximum number of rows per column-help online help-version displays version information

Reference example

Fold the line of a file named testfile to a width of 30:

[root@linuxcool] # fold-w 30 file

Use the space character as the break point:

[root@linuxcool] # fold-s file

Calculate the column width in Byte instead of the number of rows:

[root@linuxcool ~] # fold-b file on how to use linux's fold command to limit file column width is shared here. I hope the above content can be of some reference value to everyone and can be applied. If you like this article, you might as well share it for more people to see.
