equivalent of ftp put and append in scp
Put is just the normal scp
scp /path/to/source user@host:/path/to/targetAppend only works with a little hack (and not with scp directly)
cat source | ssh user@host "cat >> /path/to/target"
scp can not append (ssh can, but it is not always an option). You can copy remote file, append it locally and then put it back.
