I have incorrectly named files which are unsynced by -1. The problem is I need to rename 1000s of them. DBGC180_805754DBGC180_805755DBGC180_805756to DBGC180_805753DBGC180_805754DBGC180_805755I would prefer using bash scripts or a unix command. 
Rename multiple files to decrement number in file name?
rename;filenames;recursive
