mmv

Move and rename files in bulk.

• Rename all files with a certain extension to a different extension:

mmv "*{{.old_extension}}" "#1{{.new_extension}}"

• Copy report6part4.txt to ./french/rapport6partie4.txt along with all similarly named files:

mmv -c {{"report*part*.txt"}} {{"./french/rapport#1partie#2.txt"}}

• Append all .txt files into one file:

mmv -a "*.txt" {{"all.txt"}}

• Convert dates in filenames from "M-D-Y" format to "D-M-Y" format:

mmv "[0-1][0-9]-[0-3][0-9]-[0-9][0-9][0-9][0-9].txt" "#3#4-#1#2-#5#6#7#8.txt"
