fold1
Fold long lines for finite width output device
Usage
fold [-bs]
[-w
width]
[file ...]
Overview
The fold utility is a filter which folds the contents of the specified files, or the standard input if no files are specified, breaking the lines to have a maximum of 80 columns.
The options are as follows:
-
-b -
Count width in bytes rather than column positions.
-
-s -
Fold line after the last blank character within the first width column positions (or bytes).
-
-w width -
Specify a line width to use instead of the default 80 columns. The width value should be a multiple of 8 if tabs are present, or the tabs should be expanded using expand(1) before using
fold.
Environment
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of fold as described in environ(7).
Examples
Fold text in standard input with a width of 20 columns:
$ echo "I am smart enough to know that I am dumb" | fold -w 15 I am smart enou gh to know that I am dumb
Same as above but breaking lines after the last blank character:
$ echo "I am smart enough to know that I am dumb" | fold -s -w 15 I am smart enough to know that I am dumb
