fold: Linux Commands HowTo
fold: Wrap text to fit a specified width.
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]...
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 may count more
than one column, backspace decreases the column count, and carriage
return sets the column to zero.
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.
"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."
