When I am working with a kernel module in FreeBSD, there are times that I want to see all functions available in man 9.
I know that apropos is out there but I sometimes don't know the keyword.
Because of this, I decided to write a simple zsh script to list all available pages in a section, not only in section 9.
function ls_man() {
if [[ $# -ne 1 ]]; then
echo "Number of argument must be 1" >&2
echo "Usage: ls_man [1-9]" >&2
return 1
fi
if [[ $1 == [1-9] ]]; then
ls /usr/share/man/man$1 | awk '{ split($1, name, ".") } { print name[1] }'
return 0
else
echo "Wrong argument" >&2
echo "Usage: ls_man [1-9]" >&2
return 1
fi
}
