Use: "touch remote:path",

Short: `Create new file or change file modification time.`,
|
|
Long: `
|
|
Set the modification time on object(s) as specified by remote:path to
|
|
have the current time.
|
|
|
|
If remote:path does not exist then a zero sized object will be created
|
|
unless the --no-create flag is provided.
|
|
|
|
If --timestamp is used then it will set the modification time to that
|
|
time instead of the current time. Times may be specified as one of:
|
|
|
|
- 'YYMMDD' - eg. 17.10.30
|
|
- 'YYYY-MM-DDTHH:MM:SS' - eg. 2006-01-02T15:04:05
|
|
- 'YYYY-MM-DDTHH:MM:SS.SSS' - eg. 2006-01-02T15:04:05.123456789
|
|
|
|
Note that --timestamp is in UTC if you want local time then add the
|
|
--localtime flag.
