To wrap text files to fit a specified width in the shell, you can use the fmt command.
The fmt command is a simple text formatter that can wrap lines to fit a specified width, align text, and adjust margins.
To wrap a text file to fit a specified width, you can use the -w option to specify the width and the -s option to split long lines:
fmt -w width -s file.txt
Replace width with the desired width and file.txt with the path to the text file.
For example, to wrap the file.txt file to fit a width of 80 characters:
fmt -w 80 -s file.txt
This will reformat the file.txt file and wrap the lines to fit a width of 80 characters.
To save the output to a new file, you can use the > redirection operator:
fmt -w 80 -s file.txt > wrapped.txt
This will create a new file named wrapped.txt with the wrapped text.
You can also use the -u option to disable line wrapping and split long lines at the specified width:
fmt -w 80 -u file.txt
Keep in mind that these are just a few examples of how to wrap text files to fit a specified width using the fmt command. You can customize the options and input and output files to meet the specific requirements of your system. You should also regularly review and update the text files to ensure that they are formatted correctly and easy to read.
