curl -F file=@$1 https://hardfiles.org/ curl -F file=@$1 https://hardfiles.org/
``` ```
Additionally, you can append some extra options to modify the expiry time or file name length. Currently the file expiry time must be provided in seconds and is limited to 5 days maximum. The file name length is limited to 128 characters. The following example will return a file that expires in 48 hours rather than the default 24 and a file name length of 64 characters: Additionally, you can specify the amount of time before your upload is removed from the server. Currently the file expiry time must be provided in seconds and is limited to 5 days maximum. The following example will return a file that expires in 48 hours rather than the default of 24 hours.
