Top Forums Shell Programming and Scripting Trying to create a script to run as root, permission denied Post 302799557 by Corona688 on Friday 26th of April 2013 05:02:52 PM

This command does not do what you think it does:

Code:
sudo cat <<EOF >> launchd.conf
umask 000
EOF

Let me explain in detail the order which it does these things.
  • Redirects 'umask 000' into stdin
  • Redirects stdout into launchd.conf
  • Forks and executes 'sudo cat', letting it inherit these I/O redirections

You see the problem? It opens the files before it runs sudo. It has to -- you can't alter stdin and stdout for a program that's already running, you have to set them up first. By the time you call sudo, your shell has already tried and failed to open the file.

You have to run all that code inside sudo, since sudo is the thing with elevated permissions.

Code:
sudo bash <<EOF
        echo "umask 000" >> launchd.conf
EOF

NAME
mtailrc - Configuration file for monkeytail DESCRIPTION
A monkeytail configuration uses Apache-style syntax to declare "groups" of files to be tailed. Best explained with an example: <group testgroup> prefix 'server2: ' sudo yes <file> filename /var/log/apache2/access.log prefix 'server1: ' host server1.example.com </file> <file> filename /var/log/apache2/access.log host server2.example.com sudo no </file> </group> OPTIONS
All options can be either put inside a group or file block. Options inside a file block override those in the group block. filename filename filename defines the filename for this block. host remote-host (optional) host defines that this block's file is to be tailed on a remote server. sudo yes|no|1|0 sudo is a boolean specifying whether this file should be tailed as root. This option is supported for both local and remote files (in both cases you will potentially be prompted for your password). prefix "string: " prefix allows you to specify a short string that will be prepended to every line that is displayed for that given file.
