You can't!

On a regular file a umask of 000 will give you permissions of 666 (-rw-rw-rw-).

The key question is WHY does the user want 777 permissions? The 'x' bit is only useful for executable things like programs and shell scripts. The 'x' bit does not give you any thing more than than '666' permissions other than being able to do a ./filename to execute something.

If that file isn't a program or shell script or something very similar the 'x' permission bit is useless.

A fundamental principle of Unix is that someone, as in a human being needs to decide whether a file is executable.

A human can program a script to do this for him, but Unix security believes that default executable creation is an enormous security risk.

You'll have to write a script to change the permissions after the fact. cron can run it for you.

Hi,

It cannot be done. Files are created with r & w permissions by default. The x has to be added manually.

Hope this helps.

In my early life I tried..
.. And gave up.

But there is nothing stopping you to create an alias like cm7='chmod 777 '

then try cm7

I agree with Steven - it's a bad idea. Why would he want to create text files (other than scripts) executable?

And even more of a bad idea, to make them world-executable!

It sounds suspicious to me.

I have an alias:

alias go='chmod u+x '

that I use all the time for scripts (go myscript.sh).

If he wants to put all his executables in a directory, he could do
chmod 770 *

(I'd still question the need for world-executable permission. If there are things the world needs to run, put them in something like /usr/local/bin)

It's possible he doesn't know that he doesn't need 777, that 770 is fine (everybody in the group can execute) or even 700 (just him).
