Actually I've had trouble
IFS=: read -ra paths <<< "$PATH"
and embedded new lines.
I think this is better
find_file() {
local IFS=:
for dir in $PATH; do
[[ ! -r $dir/$1 ]] || continue
FOUND_FILE="$dir/$1"
return 0
done
echo "could not find '$1' in PATH" >&2
return 1
}
include() {
local FOUND_FILE
find_file "${1:?Missing File Name }" || return $?
source "${FOUND_FILE}"
}
includeExt() {
local FOUND_FILE
local PATH=${1:?Missing Search Path}
find_file "${2:?Missing File Name}" || return $?
source "${FOUND_FILE}"
}
Ideally what I want to do is
alias include=source\ "$(find_file "${1}")"
but that doesn't work in bash and I still haven't found a way around the
problem.
The only way I can think to do it is to use a second file.
cat <<EOF ><known_path>/source_wrapper.sh
find_file "${1:?Missing File Name }" || return $?
source "${FOUND_FILE}"
EOF
alias include=source\ "<known_path>/source_wrapper.sh"
