fold

Wrap input lines to fit in specified width, writes each FILE ('-' means standard input), or standard input if none are given, to standard output, breaking long lines.

Syntax
      fold [options]... [FILE]...

Options

   -b
   --bytes
      Count bytes rather than columns, so that tabs, backspaces, and carriage returns
      are each counted as taking up one column, just like other characters.

   -s
   --spaces
      Break at word boundaries: the line is broken after the last blank before the maximum
      line length.  If the line contains no such blanks, the line is broken at the maximum line length as usual.

   -w WIDTH
   --width=WIDTH
      Use a maximum line length of WIDTH columns instead of 80.

By default, 'fold' breaks lines wider than 80 columns. The output is split into as many lines as necessary.

'fold' counts screen columns by default; thus, a Tab can count more than one column, Backspace decreases the column count, and CarriageReturn sets the column to zero.

"The general attitude seems to be that people should wear square shoes, because squares are easier to design and manufacture than foot shaped shoes. If the shoe industry has gone the way of the computer industry it would now be running a $200-a-day course on how to walk, run and jump in square shoes" ~ Alan Kay
