Enable logging for service
I'm trying to figure out how to enable logging in Transmission.
I know I can run the daemon in the foreground:
transmission-daemon -f --logfile /your/path/to/transmission.log
But this is not what I want. I want to enable this option (logfile
) in the service instance.
I've discovered that running sudo service transmission-daemon
executes the file located in /etc/init.d/transmission-daemon
. This file (as shown below) doesn't really make me any wiser.
So far, I understand the following:
--exec $DAEMON -- $OPTIONS
executes the effective daemon. This file (as seen in the variable on top of the script) is located in /usr/bin/$NAME
. $NAME
is transmission-daemon
. This is an executable located in there.
So I think you can pass it some options (e.g., --logfile
). I added an instantiation of the OPTIONS
variable but this doesn't seem to write anything.
I tried the OPTIONS=" --logfile /smb/torrents/transmission.log"
line so that it might append them to the execution but it throws an error.
Another thing I tried was using the option without any quotes.
OPTIONS= -e /smb/torrents/transmission.log
This throws the same error:
:~$ sudo service transmission-daemon restart
/etc/init.d/transmission-daemon: 15: /etc/init.d/transmission-daemon: -e /smb/torrents/transmission.log: not found
Doing the above without -
doesn't show me any errors, but doesn't write to the log file either.
Adding the --logfile
option after the execution --exec $DAEMON --logfile /path/file -- $OPTIONS
yields another error as well:
* Restarting bittorrent daemon transmission-daemon
start-stop-daemon: unrecognized option '--logfile'
The logfile has sufficient permissions, though:
-rwxrwxrwx 1 debian-transmission debian-transmission 0 Dec 30 11:14 transmission.log*
My question is, how to do this exactly?
#!/bin/sh -e

Solution 1:
I fixed it in the meanwhile. There is a file in /etc/default/
named transmission-daemon
as well (see below). This file has an instantiation for the OPTIONS
parameter. I just added --logfile /path/to/logfile
and it worked fine!
# defaults for transmission-daemon
# sourced by /etc/init.d/transmission-daemon
# Change to 0 to disable daemon
ENABLE_DAEMON=1
# This directory stores some runtime information, like torrent files
# and links to the config file, which itself can be found in
# /etc/transmission-daemon/settings.json
CONFIG_DIR="/var/lib/transmission-daemon/info"
# Default options for daemon, see transmission-daemon(1) for more options
OPTIONS="--config-dir $CONFIG_DIR --logfile /path/transmission.log"
# (optional) extra options to start-stop-daemon
#START_STOP_OPTIONS="--iosched idle --nicelevel 10"
