You can utilize the power of pygmentize with less - automatically! (No need to pipe by hand.)
Write a file ~/.lessfilter
#!/bin/sh
case "$1" in
*.awk|*.groff|*.java|*.js|*.m4|*.php|*.pl|*.pm|*.pod|*.sh|\
*.ad[asb]|*.asm|*.inc|*.[ch]|*.[ch]pp|*.[ch]xx|*.cc|*.hh|\
*.lsp|*.l|*.pas|*.p|*.xml|*.xps|*.xsl|*.axp|*.ppd|*.pov|\
*.diff|*.patch|*.py|*.rb|*.sql|*.ebuild|*.eclass)
pygmentize -f 256 "$1";;
.bashrc|.bash_aliases|.bash_environment)
pygmentize -f 256 -l sh "$1"
;;
*)
grep "#\!/bin/bash" "$1" > /dev/null
if [ "$?" -eq "0" ]; then
pygmentize -f 256 -l sh "$1"
else
exit 1
fi
esac
exit 0
In your .bashrc add
export LESS='-R'
export LESSOPEN='|~/.lessfilter %s'
Also, you need to make ~/.lessfilter executable by running
chmod u+x ~/.lessfilter
