Linux file copy with ETA?
Solution 1:
Use rsync --human-readable --progress
.
For single files and block devices there's also pv
. And if you genuinely need an accurate progress bar, try using tar
with pv — something like this:
source=/the/source/directory
target=/the/target/directory
size=$(du -sx "$source")
cd "$source"
find . xdev -depth -not -path ./lost+found -print0 \
| tar --create --atime-preserve=system --null --files-from=- \
--format=posix --no-recursion --sparse \
| pv --size ${size}k \
| { cd "$target"; \
tar --extract --overwrite --preserve-permissions --sparse; }
Be warned, however, that GNU tar
does not yet support ACLs or extended attributes, so if you are copying filesystems mounted with the "acl" or "xattrs" options, you need to use rsync (with the "--acls
" and "--xattrs
" options). Personally, I use:
rsync --archive --inplace --hard-links --acls --xattrs --devices --specials \
--one-file-system --8-bit-output --human-readable --progress /source /target
Also look into whether you want to use the --delete
and/or --numeric-ids
options.
Solution 2:
Instead of dd
I would suggest pv
, e.g.:
% tar -cf - INPUT | pv -rbe -s SIZE | tar -xf - -C DEST
Solution 3:
Have you tried rsync -P
? If you're using dd
, e.g. tar -cf - src | dd | (cd dest; tar -xf -)
you should be able to use Ctrl-T (SIGINFO) to see your progress.
