Sometimes you do strange stuff with your Linux PC.
I did yesterday, when I was experimenting with what would happen if I would chmod /usr/bin/chmod to 000. That gave me some problems. Solution from: Linux Magazine

Consider sponsoring me on Github. It means the world to me if you show your appreciation and you'll help pay the server costs.

You can also sponsor me by getting a Digital Ocean VPS. With this referral link you'll get $200 credit for 60 days. Spend $25 after your credit expires and I'll get $25!

If the CHMOD program is not executable anymore, you should start it via the linker.

Execute this command:

/lib/ /bin/chmod 755 /bin/chmod 

This also works for other programs, just as long you know the original path to it...

Edit: 777 edited to 755,
Here is another solution thanks to: Rainer Weikusat

perl -e 'chmod(0755, "/bin/chmod")'
