This is probably a duplicate, but all my searches are turning up questions about permission denied errors.
I am running a command in a bash shell. I want to redirect output to append to a file that probably does not exist on the first run. I want to set specific file permissions mode if output redirection has to create this file. Is there a way to do this with one command?
For example, I might try
foo >> /tmp/foo.log 0644
0644 are the permissions I want
foo.log to end up with. Most commands I've experimented with in bash end up interpreting
0644 as an additional argument to
I get the feeling that this is going to take a second command to
chmod the permissions before or after writing to it.
I am using GNU bash 4.2.25 and Ubuntu 12.04, if that makes a difference - general answers are preferred.
