ignore files in use (being written to) when using rsync
To check if a file is currently open (if a file is currently written is for sure open by some process) the standard way is to use lsof
:
if lsof /your/file > /dev/null; then echo "file currently open"; fi
You can use this snippet to filter find results for only not opened files and use them to feed rsync:
find . -type f -exec sh -c 'if ! lsof `readlink -f {}` > /dev/null; then echo `basename {}`; fi' \; | tr '\n' '\0' | rsync -avz --from0 --files-from=- ./ user@host:destination/
Some notes:
readlink -f
is needed to have full path of a file, lsof accept only full pathtr '\n' '\0'
