chmod rx invalid

jaime@OpticaOmegaPlus:~$ echo 'date %T' >/tmp/midate; chmod rx /tmp/midate; /tmp/midate chmod: invalid mode: ‘rx’ Try 'chmod --help' for more information. -bash: /tmp/midate: Permission denied 

Could someone tell me why it does not work

You're doing it wrong.

$ echo 'date +%T' >> /tmp/Temp_date && chmod +rx /tmp/Temp_date && /tmp/Temp_date 08:32:18 

• You need to add + sign before rx.
• You need to add + sign before %T to ensure it recognized by date.
• With all command fail, meaning you have not add content to file named midate on /tmp, that's why bash refuse to execute. As it was not valid script.
