How to filter files when using scp to copy dir recursively?
I'd probably recommend using something like rsync for this due to its include and exclude flags, e.g:-
rsync -rav -e ssh --include '*/' --include='*.class' --exclude='*' \server:/usr/some/unknown/number/of/sub/folders/ \ /usr/project/backup/some/unknown/number/of/sub/folders/Some other useful flags:
-rfor recursive-afor archive (mostly all files)-vfor verbose output-eto specify ssh instead of the default (which should be ssh, actually)
There is no feature in scp to filter files. For "advanced" stuff like this, I recommend using rsync:
rsync -av --exclude '*.svn' user@server:/my/dir .(this line copy rsync from distant folder to current one)
Recent versions of rsync tunnel over an ssh connection automatically by default.
