But that raises another question.
Why does error message identify a protocol problem after having correctly
identified the problem as "No such file or directory".
man rsync says:
"EXIT VALUES
0 Success
1 Syntax or usage error
2 Protocol incompatibility
[etc]
"
An *exit value* (aka exit status) is an entirely
different concept to an "error number".
Exit status is partially explained here:
http://mywiki.wooledge.org/BashGuide/TestsAndConditionals?highlight=%28exit%29%7C%28status%29#Exit_Status
The exit status = 2 mentioned in the man page has nothing
to do with the 2 in the error message
"rsync: change_dir "/media/root/drescued_commo" failed: No such file
or directory (2)"
The 2 in that message is a reference to errors reported by the standard
library of the C programming language, as explained here:
