[SOLVED] single command for creating file and setting permission to it.

Ankit yadav · 06-26-2017, 06:03 AM

Hi All,

I want to know is there is any command which let me create file and set to some permission(other than default).

Like we can do with directories with command
mkdir -m 777 testdir

Some where I found "install" command. But again i successfully able to create directory from it, not file.

Is there is any way to do it. Or we should follow touch file;chmod 777 file command itself.

Thanks in Advance.

No 'single command'. EDIT: corrected to Yes, in post#5 below; see man install
Have a study of: man creat
There's always umask: https://unix.stackexchange.com/quest...-touch-command
Oh, maybe visit my favorite command: strace

Enjoy your Linux!

It depends on how you define "single command". You can string several commands into one "script", and run the script as a single command. But caveats, as when you lose the script you might not remember the commands. And if you're on someone else's system, they wont have your script.

correct it is more done in steps, first create, then change permissions two commands one line

Code:

$⚡ ~ ⚡> touch changePermissionsOnMe ; chmod 777 changePermissionsOnMe

Oh: ooops: I found this (/dev/null 'trick' to make install 'work'):
https://unix.stackexchange.com/quest...e-command-line

Code:

install -m 7666 /dev/null MYrwSrwSrwT
ls -l !$ ; echo hi > !$ ; ls -l !$ #echo stole my Suid;Idk WHY?

is devilishly BWeatiful

Thanks OP, for getting me to learn install

p.s. Got milkstdin?: echo hi | install -m 7666 /dev/stdin MYrwSrwSrwT
