fold: Wrap each line to default width (80 characters).

fold

$ fold ${filename}

try on your machine

The command "fold ${filename}" is used to format the text within the specified file by breaking long lines into multiple lines with a specific width.

Here's how it works:

"fold" is the command itself.
"${filename}" is the name or path of the file you want to apply the fold command to. It could be replaced with the actual name or path of the file you are working with.

When you run this command, the text in the file will be formatted according to the default fold width, which is usually 80 characters. Any lines longer than the specified width will be broken into multiple lines. The original file will not be modified; instead, the output will be displayed on the terminal or can be redirected to another file if desired.

For example, if you have a file named "example.txt" with a paragraph containing long lines, running the command "fold example.txt" will format the paragraph by breaking the lines into multiple lines with a width of 80 characters.
