Log file a little messy: hard to seek what it's important

[MilesTEG1]

Hello,
I just check the log of the container, and it's really hard to read.

There is too much unwanted information for me...

I had made a script to launch the commands for me, on my mac, checking if the binaries are installed, and here a portion of the log I get:

Here a portion of what generate the log (I was greatly inspired by your work for the ts and tee commands ^^ except I use touch instead of curl to create the logfile.)

for user in "${user_list[@]}"; do
    config_full_path="${config_path}/config_${user}"
    printf "     --> Synchronisation pour %s :\n" "${user}" 2>&1 | ts '[%Y-%m-%d %H:%M:%S]' | tee -a "${LOG_FILE}"

    if [[ "${AUTO_DISCOVER}" == "true" ]]; then
        printf "AUTO_DISCOVER est à true :\n" 2>&1         | ts "[%Y-%m-%d %H:%M:%S]            --  " | tee -a "${LOG_FILE}"
        vdirsyncer -v INFO --config "${config_full_path}" discover  2>&1    | ts "[%Y-%m-%d %H:%M:%S]                --  " | tee -a "${LOG_FILE}"
    fi
    vdirsyncer -v INFO --config "${config_full_path}" metasync  2>&1    | ts "[%Y-%m-%d %H:%M:%S]            --  " | tee -a "${LOG_FILE}"

    printf "     --> Fin de la synchronisation pour %s.\n" "${user}" 2>&1 | ts '[%Y-%m-%d %H:%M:%S]' | tee -a "${LOG_FILE}"
done

If you could do something, it would be great. And I can get put definitively vdirsyncer on my NAS with docker.
