No need to leave R, which has some 9 one-letter symbols, 35 two-letter 
symbols, and 121 three letter symbols in the base and core packages.  It 
is just unreal.  (The equivalent numbers from my Linux system are 3, 56, 
and 148, and one of those one-letter commands is R!!)

Generated from R --vanilla with:

for (p in c("base", "boot", "class", "cluster", "codetools", "datasets",

"MASS", "Matrix", "methods", "mgcv", "nlme", "nnet", "rpart", "spatial", 
"splines", "stats", "stats4", "survival", "tcltk", "tools", "utils")) 
library(p, character.only=TRUE)
rm(p)
one <- unique(grep("^[[:alnum:]]+$", apropos("^.$"), value=TRUE))
two <- unique(grep("^[[:alnum:]]+$", apropos("^..$"), value=TRUE))
three <- unique(grep("^[[:alnum:]]+$", apropos("^...$"), value=TRUE))

and from the bash shell with

ls -1 {/usr,}/bin/? 2>/dev/null
ls -1 {/usr,}/bin/?? | perl -ne 'print substr $_,-3' | sort -u | wc -l
ls -1 {/usr,}/bin/??? | perl -ne 'print substr $_,-4' | sort -u | wc -l
