awk -F command is not found (ubuntu)

I am using the command in following types:

Commands are:

• ps -ef | awf-F "" '{print $2}'
• ps -ef | grep python3 | awk-F "" '{print $3}'

Both the commands give the error:

• awk -F command is not found

Are you sure you are using the correct command? Have you tried using awk -F with a space in between?
