有吗？
我可以这样使用:
$ cat someFileWithLongLines.txt | wrap -80 --indent|less
最佳答案
GNU coreutils 有一个命令叫 fmt :
$ fmt -40 -t lorem
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
Edit: As you can see, fmt breaks lines on word boundaries within the given width. Contrast this with the hard boundary of fold. The type of indenting that fmt does may not be what you're looking for, but you can pipe it (without the -t option) through pr to get a margin-style indent:
fmt -40 lorem | pr -To 6
