Usage: ufw [-RsF] [-D num] [file/url]
Flags:
-R|--remove-file # Remove the file after uploading.
-d|--description # Supply a description.
-p|--public # Make the file public.
-n|--no-notify # Don't send immediate notifications for this upload.
--notify # Force a notification for this upload.
-u|--shorten <URL> # Generate a shortlink from URL.
-S|--short-url # Get a shortlink when uploading a file.
-P|--page-url # Get a link to the file page instead of a direct one.
-m|--max-filesize <num>[suf] # Maximum filesize (takes K, M and G suffixes).
-a|--album-id # Add the file to an album.
-A|--album-name # Add the file to an album by name. The album will be created, if necessary.
-t|--tags "<tag1[, tag2,..]>" # Add tags to the file.
-q|--quiet # Be quiet.
-v|--void # Don't add the file to my files.
Config options (~/.config/ufw):
secret # Your personal token. Get it at https://zfh.so/settings_form
cfg_max_filesize # Maximum filesize (takes K, M and G suffixes).
# Others are self-explanatory:
cfg_url_regex
cfg_tmp_dir
cfg_service_url
Environment variables:
UFW_CFG_FILE # Config file to read, defaults to \$XDG_CONFIG_DIR/ufw
UFW_SECRET # Your API secret
UFW_TMP_DIR
