The appended number will change, and I won't know the file name in advance. If there were only one... (1 Reply)

As many will point out, one of the benefits of using rsync (without --delete) is that it will sync files between source and destination, but not delete files in the destination which HAVE been deleted in the source. Well, I have kind of the opposite problem and I'm wondering if there are date... (2 Replies)

tensor - a N*N tensor, N=1,2,3 SYNOPSYS
The tensor class defines a 3*3 tensor, as the value of a tensorial valued field. Basic algebra with scalars, vectors of R^3 (i.e. the point class) and tensor objects are supported. IMPLEMENTATION
