fmt: Reformat a file without joining lines shorter than the given width together.
$ fmt -s ${filename}
try on your machine
The command "fmt -s ${filename}" is used to format the content of a specified file in a specific way.
Here's a breakdown of the command:
- "fmt": This is the main command, short for "format." It is a command-line utility in many Unix-like operating systems used to format the text in files or standard input.
- "-s": This is an option or flag for the "fmt" command. In this case, it stands for "split," indicating that the text should be split into individual lines based on the available width of the output device.
- "${filename}": This is a placeholder for the name of the file you want to format. In practice, you would replace "${filename}" with the actual name of the file you wish to format.
So, when you execute the "fmt -s ${filename}" command, it takes the content of the specified file and formats it, splitting it into individual lines based on the available width of the output device. The resulting formatted text is then displayed on the screen or can be redirected to another file or command.
