NAME
fold - wrap each input line to fit in specified width
SYNOPSIS
fold [-bs] [-w width] [--bytes] [--spaces] [--width=width] [file...]
DESCRIPTION
This manual page documents the GNU version of fold. fold prints the
specified files, or the standard input when no files are given or the
filename `-' is encountered, on the standard output. It breaks long
lines into multiple shorter lines by inserting a newline at column 80.
It counts screen columns, so tab characters usually take more than one
column, backspace characters decrease the column count, and carriage
return characters set the column count back 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. If the line contains any blanks, the line
is broken after the last blank that falls within the maximum line
length. If there are no blanks, the line is broken at the maximum
line length, as usual.
-w, --width width
Use a maximum line length of width columns instead of 80.
The long-named options can be introduced with `+' as well as `--', for
compatibility with previous releases. Eventually support for `+' will be
removed, because it is incompatible with the POSIX.2 standard.
