log format This parameter allows you to specify the format used for logging file transfers when transfer logging is enabled. The format is a text string containing embedded single-character escape sequences prefixed with a percent (%) character. An optional numeric field width may also be specified between the percent and the escape letter (e.g. "%-50n %8l %07p"). In addition, one or more apostrophes may be specified prior to a numerical escape to indicate that the numerical value should be made more human-readable. The 3 supported levels are the same as for the --human-readable command-line option, though the default is for human- readability to be off. Each added apostrophe increases the level (e.g. "%''l %'b %f").
