Some UNIX programs - usually background or daemon programs - insist on writing a log file. You might not want the log file itself as much as you want the disk space that the log file takes. Here are a few tips:
Some programs will write to a log file only if the log file exists. If the program isn't running, try removing the log file.
If you remove a log file and the program recreates it, look for command-line options or a configuration file setup that tells the program not to make the log file.
If your system has, try replacing the log file with a symbolic link to :
ln -s /dev/null logfile
If you're lucky, the program won't complain and will throw all its messages in the bit bucket. Watch out for programs that run at reboot or from the systemto truncate and replace the log file. These programs might replace the symbolic link with a small regular file that will start growing again.
Does a system mailbox for a user like uucp keep gettingthat you want to throw away? You may be able to add a .forward file to the account's home directory with this single line:
Or add an alias in the system mail alias file that does the same thing:
If your system has a command like newaliases to rebuild the alias database, don't forget to use it after you make the change.
