Top Forums UNIX for Advanced & Expert Users Stop root from writing to directory Post 303041559 by Neo on Wednesday 27th of November 2019 09:11:51 PM

This is a trivial problem to solve without any necessity to tinker with root permissions, etc.

So, when I have this kind of problem (and I have seen the kind of problem often), I would just remove the directory that your process is trying to write to. Problem solved.

In the next case:

If the process writes to a directory you do not want to remove because other processes write to the same directory and you don't want to reconfigure other processes to write to a different directory, then I would just create a crontab file which runs often and deletes the files you want deleted.

In the case where the file name of the log is the same, then just link the name of that file to /dev/null and problem solved. No need for a cron process..

In other words, there are many ways to solve this simple annoying problem.. These are but a few ways to do it.

This is also an example of why it is best, by far, to get people who post here at unix.com to describe the exact problem they are trying to solve, generally speaking.

NAME
rmdir, rm - remove (unlink) directories or files SYNOPSIS
rmdir dir ... rm [ -f ] [ -r ] [ -i ] [ - ] file ... DESCRIPTION
Rmdir removes entries for the named directories, which must be empty. Rm removes the entries for one or more files from a directory. If an entry was the last link to the file, the file is destroyed. Removal of a file requires write permission in its directory, but neither read nor write permission on the file itself. If a file has no write permission and the standard input is a terminal, its permissions are printed and a line is read from the standard input. If that line begins with `y' the file is deleted, otherwise the file remains. No questions are asked and no errors are reported when the -f (force) option is given. If a designated file is a directory, an error comment is printed unless the optional argument -r has been used. In that case, rm recur- sively deletes the entire contents of the specified directory, and the directory itself. If the -i (interactive) option is in effect, rm asks whether to delete each file, and, under -r, whether to examine each directory. The null option - indicates that all the arguments following it are to be treated as file names. This allows the specification of file names starting with a minus. SEE ALSO
