Dear Maintainer, Latest version of /usr/bin/prename (which provides "rename") provided by package "perl" warns that "Deprecated program in use: rename as shipped with the Debian perl package will be removed after the release of stretch. Please install the separate 'rename' package which will provide the same command." However, the command provided by package "rename" is not the exact same command. For example the "-n" option functions cosmetically differently: $ touch AbcAbc DefAbc FoobazAbc $ prename -n 's/Abc$//' * Deprecated program in use: rename as shipped with the Debian perl package will be removed after the release of stretch. Please install the separate 'rename' package which will provide the same command. AbcAbc renamed as Abc DefAbc renamed as Def FoobazAbc renamed as Foobaz $ rename -n 's/Abc$//' * rename(AbcAbc, Abc) rename(DefAbc, Def) rename(FoobazAbc, Foobaz) While the difference is cosmetic, output of "prename" feels more readable.
