Although a more elegant solution, still a dupe: Even more elegant, however: rename 'y/ /_/' *

Actually you doesn't need the \ before the since you quoted the expression. To substitute all ocurrences, put the 'g' flag after the last slash. I think the 'y' or 'tr' solution above is good but for change many spaces to a single underscore you may try this: rename 's/\s+/_/g' *
