I was dumb enough to not modify path

nhatz.sh

#!/usr/bin/sh

# Execute the script specified as argument

# Directory where the script are stored
baseDir=/opt/nhatz_bash

passed_args=("$@") 								#list of provided arguments stored in new array
comm=$1 									#script/command to call, first on the list
comm_pos=0 									#position of $comm in the array
new_args=(${passed_args[@]:0:$comm_pos} ${passed_args[@]:$(($comm_pos + 1 ))}) #list of arguments without $comm
	
if [ -d $baseDir/$comm ]; then
	$baseDir/$comm/$comm.sh $(echo ${new_args[@]}) 
else
	echo "[Nhatz] Unknown commad: $comm"
