rsync include / exclude
Hi, I'm using rsync to move the contents of one drive to another as part of upgrading from an old Linux installation to a newer one. I have a script which uses includes and excludes to select what to keep and what to throw away, but for some reason my include rule isn't triggering when I think it should. I've narrowed it down to a test script for a representative case which, again, should be working but isn't. The test script is trying to say include anything in /usr/etc and its subdirectories from the source tree, and exclude everything else. For some reason, this isn't working. Obviously, I've misunderstood some aspect of how rsync works. Does anyone see the problem? TIA. script: --- #!/bin/bash SRC=/home/mcdavis/mtmaxtor/ DEST=/home/mcdavis/frommaxtor/ # Here is a set of attempts to include, none of which work. rsync -aHvn --compare-dest=/ --include=/usr/etc/* --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=/usr/etc/ --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=/usr/etc --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=/usr/etc/** --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=/usr/etc* --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=usr/etc/* --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=usr/etc/ --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=usr/etc --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=usr/etc/** --exclude=* $SRC $DEST rsync -aHvn --compare-dest=/ --include=usr/etc* --exclude=* $SRC $DEST # End of script.

But only slightly less well known is this: Never exclude '*', when death is on the line! Ha ha ha ha ha! Ha ha ha ha! [Clunk!] Inconceivable! OK, guilty as charged. I started looking at rsync two days ago. Here's a serious answer: Always include ALL the parent dirs when excluding '*'. Also, consider using a less powerful trailing exclusion. In the following example, I've put the include and exclude rules into a single file named excl: % cat excl + /usr/ - /* + /usr/etc/ - /usr/* % rsync -aHvn ... --exclude-from=excl $SRC $DEST Or: % cat excl + /usr/ + /usr/etc/ + /usr/etc/** - * Note that the last two includes in the latter example are both necessary, as the last one only includes what's inside the directory, but not the directory itself. Yes, I see I should have been more careful of the Rules of Unusual Significance (R.O.U.S.'s). Your explanation and the man page on the Samba site make it clear that if a parent directory is excluded, then all of its descendents are also excluded. The man page I'd been looking at pertained to an older rsync version and was less explicit about how include/exclude works. (That rule you keep using ... I don'ta think it means what you think it means.)
