bash-command not found; for every command == fear i could screwed up the path here is the output of echo $PATH

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin


and when I gave cat /etc/paths this is the output

/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin


I am not sure whether that /usr/local/bin is creating the error (command not found)

Thank u for your suggestions
Commands you run in Terminal need to either in one of the directories included in $PATH or you need to call them with ./command if you are in the directory the command is stored in.
