- // 3. rsync @src:dir/ @dest:location
- //
- // We will explain each of these in turn.
- //
- // 1. Copy a single file. We'll split this up like so:
- //
- // rsync @src:file.txt /tmp/tmpdir
- // rsync /tmp/tmpdir/file.txt @dest:location
- //
- // Since /tmp/tmpdir is empty, we could also rsync from
- // '/tmp/tmpdir/' if we wished.
- //
- // 2. Copy a directory. A directory with the same name
- // is copied to the destination. We'll split this up like so:
- //
- // rsync @src:dir /tmp/tmpdir
- // rsync /tmp/tmpdir/dir @dest:location
- //
- // The result is that everything in 'dir' is copied to @dest,
- // and ends up in 'location/dir'.
- //
- // 3. Copy the contents of a directory. We will split this
- // up as follows:
- //
- // rsync @src:dir/ /tmp/tmpdir
- // rsync /tmp/tmpdir/ @dest:location
- //
- // After the first rsync, everything in 'dir' will end up in
- // tmpdir. The second rsync copies everything in tmpdir to
- // @dest:location without creating an encapsulating folder
- // in the destination (i.e. there is no 'tmpdir' in the destination).
- //
- // All three of these cases need to be handled correctly in order
- // to ensure the correct results. In all cases the first
- // rsync always copies to $tmpDir, however the second rsync has
- // two cases that depend on the source path. If the source path ends
- // in /, the contents of a directory have been copied to $tmpDir, and
- // the contents of $tmpDir must be copied to the destination. Otherwise,
- // a specific file or directory has been copied to $tmpDir and that

- // the destination.
