Change the case of files at one go

Sometimes when we are copying file from a CD(which contain the files written from MS windows)to linux system, all the files name appear in the capital letters. Since in Linux, file names are generally in lower case, we would naturally want to rename all file names to lower case letters at one go. In this case, instead of renaming all files one by one using the mv command, we can execute the following command to change the file names to lower case:

convmv --lower --notest*
This will change all file names in current directory to lower case.
