Hi Claude, > Could someone help. I have chosen a bad naming convention for a long list, and > I need to make a small alteration. The list looks like the following > 001-Fig 1-1.jpg > 013-Fig 4-4a.jpg > 024-Fig 5-6.jpg > 035-Fig 5-17.jpg > etc... > I would like to add a 0 to each group of three numbers at the beginning of > each name so that 001-Fig 1-1.jpg becomes 0010-Fig 1--1.jpg for example. > Could someone help me with the quick way to do this? Provided you have vim installed: :%s/-F/0-F/g Oliver.
