batch rename files in bash todo, tools, use-this-cmd
Let’s say we want to remove the prefix one from a series of files. Use this: 
for FILE in one* ; do mv $FILE `echo $FILE | sed 's/one//'` ; done
Or, use +rename+. Thanks to the reader who pointed out that, in Debian GNU Linux (for example), you can also use rename, as in 
rename 's/^one//' one*
Much cleaner, if rename is available.
