+dit(bf(log format)) The "log format" option 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").
+
+The default log format is "%o %h [%a] %m (%u) %f %l", and a "%t [%p] "
+is always prefixed when using the "log file" option.
+(A perl script that will summarize this default log format is included
+in the rsync source code distribution in the "support" subdirectory:
+rsyncstats.)
+
+The single-character escapes that are understood are as follows:
+
+quote(itemize(
+ it() %a the remote IP address
+ it() %b the number of bytes actually transferred
+ it() %B the permission bits of the file (e.g. rwxrwxrwt)
+ it() %c the checksum bytes received for this file (only when sending)
+ it() %f the filename (long form on sender; no trailing "/")
+ it() %G the gid of the file (decimal) or "DEFAULT"
+ it() %h the remote host name
+ it() %i an itemized list of what is being updated
+ it() %l the length of the file in bytes
+ it() %L the string " -> SYMLINK", " => HARDLINK", or "" (where bf(SYMLINK) or bf(HARDLINK) is a filename)
+ it() %m the module name
+ it() %M the last-modified time of the file
+ it() %n the filename (short form; trailing "/" on dir)
+ it() %o the operation, which is "send", "recv", or "del." (the latter includes the trailing period)
+ it() %p the process ID of this rsync session
+ it() %P the module path
+ it() %t the current date time
+ it() %u the authenticated username or an empty string
+ it() %U the uid of the file (decimal)
+))
+
+For a list of what the characters mean that are output by "%i", see the
+bf(--itemize-changes) option in the rsync manpage.
+
+Note that some of the logged output changes when talking with older
+rsync versions. For instance, deleted files were only output as verbose
+messages prior to rsync 2.6.4.
