Hello !
聽聽I'm recently in a shell scripting mood, and I came up with some small
code that makes ri output look a fair deal nicer (at least on my box).
If you put the following function definition in your shell's init script
(such as .bashrc or .zshrc) and use ril instead of ri, you'll be pleased 
ril () {
聽聽聽聽聽聽聽聽ri -T -f ansi "$@" | less -r
}
聽聽I wish a good day (or night) to all of you...
聽聽Vince
Why not just set the RI and PAGER environment variables?

Hello !
ril () {
ri -T -f ansi "$@" | less -r
}Why not just set the RI and PAGER environment variables?
That's a good point, but you don't always want less to have the -r
option, don't you ?

To be honest, I never use the pager with ri.

Why doesn't ri have --pager option?
