fold

Folds long lines for fixed-width output devices. More information: https://www.gnu.org/software/coreutils/fold.

Fold lines in a fixed width:

fold --width {{width}} {{path/to/file}}

Count width in bytes (the default is to count in columns):

fold --bytes --width {{width_in_bytes}} {{path/to/file}}

Break the line after the rightmost blank within the width limit:

fold --spaces --width {{width}} {{path/to/file}}
