editor vi: set permission in vi

 When I write bash script after that I have to set permission. How can we create script with execute permission? Try vi!

Usually that's the way:

vi blaha_zdochni.sh

write script 

[slusny_clovek@testing_server_for_mankind ~]$ ll blaha_zdochni.sh

-rw-rw-r-- 1 slusny_clovek zbohom_fico 74 Mar  7 12:22 blaha_zdochni.sh

As you see the file has not execute permission. 

There are 2 possibilities 

1) use the umask 

- but I think this is not a good choice....umask set every new files and directories but we need only script

2) use some "magic" in vi editor:

- edit this script

vi blaha_zdochni.sh

#!/bin/bash

echo I am the best prostitute on the world! Please pay me!

echo What is rm -rf? Can I start this command for my better life?

- set insert mode

- now :w - as write - !set command

:w !chmod 700 /home/betterslovakia/blaha_zdochni.sh

W12: Warning: File "blaha_zdochni.sh" has changed and the buffer was changed in

Vim as well

See ":help W12" for more info.

[O]K, (L)oad File:

- then enter

-then :wq

- check the permissions 

- [slusny_clovek@testing_server_for_mankind ~]$ ll blaha_zdochni.sh

-rwx------ 1 slusny_clovek zbohom_fico 188 Mar  7 12:29 blaha_zdochni.sh

-rwx as owrner = 700!
