There are many situations where batch renaming software can be useful. Features include changing the dates of files and changing the file attributes (such as the write protected attribute). Some batch rename software can do more than just renaming filenames. Use a text file as a source for new file names.Add a number sequence (001,002,003.) to a list of files.Extracting information from the files, such as Mp3 ID3 tags, and putting it in the filename.Setting the capitalization of the letters in the filenames.Find a string within the filename and replace it with another, or remove it.Most batch renamers share a basic set of functions to manipulate the filenames: Such software can be more or less advanced, but most have the same basic functions.īatch renaming can also be referred to as 'mass file renaming', rename 'en masse' and 'bulk renaming'. Some sort of software is required to do this.

Please consider converting them to full citations to ensure the article remains verifiable and maintains a consistent citation style. Now should you mess up with the previous commands you can remove a prefix/suffix: for old in *.This article uses bare URLs, which are uninformative and vulnerable to link rot. If you're less familiar with sed, this is equivalent to: for old in *.jpg do new=`echo $old | sed -e's/.jpg$/_suffix.jpg/'` mv "$old" "$new" done This is useful because you get the additional power of sed so that you can use the same pattern to add a suffix: # \1 might be $1 for youįor old in *.jpg do new=`echo $old | sed -e's/(.jpg)$/_suffix\1/'` mv "$old" "$new" done This uses sed search and replace to replace the start of the string ^ with prefix_. Add a prefixĭry-run command ) for old in *.jpg do new=`echo $old | sed -e's/^/prefix_/'` echo "$old - $new" doneįor real: for old in *.jpg do new=`echo $old | sed -e's/^/prefix_/'` mv "$old" "$new" done This is designed as a way to get more power whilst relying on the simplest of commands and still a one-liner. This expands a bit on the accepted answer here and combines it with another answer from Unix.SE. In the specific example requested, you'd use: rename 's/^/new./' original.filename This allows you to write any Perl substitute or transliterate command to map file names. Print STDERR "rename failed: $was - $!\n" Print STDERR "rename failed: $was - $_ exists\n" My($usage) = "Usage: $0 perlexpr \n" ĭie $usage unless getopts('fnxV', \%opts) # Rename files using a Perl substitute or transliterate command I use a Perl script called rename, which I originally dug out from the first edition Camel book, circa 1992, and then extended, to rename files. This renames foo1 to foo01, and foo10 to foo010, etc. It replaces the from part of the file names with the to, and the example given in the man page is: rename foo foo0 foo? foo? That version of rename has a fairly limited functionality: rename from to file. I've seen people mention a rename command, but it is not routinely available on Unix systems (as opposed to Linux systems, say, or Cygwin - on both of which, rename is an executable rather than a script).
