Logging

Enable

With the -l flag you can enable log file writing. If supplied, your terminal window will no longer show outputs, but instead this will be output to a log file within the path of the directory. Useful for scripting.

For example

dfg -l -d /path/to/files

Will result in a log file:

/path/to/files/dfg.log

The log file will append, which means every time you run the the application, new log entries will follow older entries.

Location

The default location of the log file, if you specify -l only, will be the directory of the scanned path; however, you can specify your own directory by using the -log flag.

For example:

dfg -l -log /var/log/pictures.log -d /mnt/usb/pictures/

Timestmp

As log files append, you may want to create a new log file each time the program is run. To do this, add the date command to the -log flag:

dfg -l -log /var/log/$(date +%F)_pictures.log -d /mnt/usb/pictures/

Output
