Limit characters per line when viewing manual pages.

MANWIDTH=70 man 7 man
Typographically speaking, it's generally the [accepted wisdom][1] that about 60 characters per line makes for optimal reading (would that more Web pages followed this convention!). I know I got tired of reading manpages with text as wide as my screen! However, the command above sets manwidth to 70 rather than 60 because paragraphs in manpages are generally indented. I recommend the following snippet for your .${SHELL}rc, which sets manwidth to 70 unless your terminal is smaller than 70 characters: function man () { if [[ $COLUMNS -gt 70 ]]; then MANWIDTH=70 command man $* else command man $* fi } [1]: https://en.wikipedia.org/wiki/Column_(typography)

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
