In bash, how can one test whether an executable program is found in
the executable search path? Thanks.

if command -v cmd > /dev/null 2>&1; then
echo "there is a cmd command available"
fi

If you want to search for cmd in $PATH and not as a builtin or
function, you can use type -P instead of "command -v" but that's
bash specific.
