The problem with todays environment is that there is real-executables,
aliases and functions. Aliases are pretty much lame in bash so everyone
uses functions (which can take arguments, etc).
But in the end, there are in fact 3 places to look for a definition. So
about a month ago I wrote this:
wh() {
prog="$1"
if [ "`declare -F $prog`" != "" ] ; then
declare -f $prog
elif alias $prog > /dev/null 2>&1 ; then
alias $prog
else
which $prog
fi
}
Which if you use in replace of `which` checks all three sources and
reports the definition or location to you.
# wh ifconfig
/sbin/ifconfig
# wh wh
wh ()
{
prog="$1"
