If you have ever sat in front of a folder full of IMG_20260814_xxx.jpg files and typed a for loop in bash to rename them, you have already written the kind of code that a purpose-built tool does better. The first time you reach for mmv, vidir, or F2, you save a few minutes. The third or fourth time, the savings add up to a real chunk of an afternoon. The Linux world has more than two dozen terminal-based batch renamers that are free and open source, and the honest answer to “which one should I use” is “what kind of renaming are you doing?” This article groups twenty-two of those tools by what they are best at, so you can pick the right one instead of installing a stack of them and forgetting which does what.
Before walking the list, a quick note on what “batch renamer” means here. A batch renamer is a tool that takes a set of files and rewrites their names based on a rule, a template, or a visual edit. The rule can be a regex (a pattern that matches parts of text and lets you rearrange or substitute them), a shell-style placeholder, an interactive list you edit in your text editor, or a TUI (text-based user interface) you navigate with the keyboard. Console renamers do not need a desktop, they run fine over SSH, they are lighter on memory than a graphical tool, and they compose well with the rest of your shell pipeline.
The editor-driven tools: when you want to see and edit
A surprising number of renamers throw away the regex idea entirely and let you edit the file list in your normal text editor. The pattern is the same: dump the current names to a temp file, open it in $EDITOR, and rename whatever the user saves. This is the right shape when you want to eyeball the names before committing, when the renaming does not follow a clean rule, or when you are doing one-off cleanup that a regex would be slower to write than to edit by hand.
vimv and massren are the canonical examples in this group. vimv opens the list in Vim (a popular modal text editor), massren uses whatever editor you have configured. mmv and vidir do the same idea with a few extra knobs: mmv lets you write a Perl-style expression and previews the result before applying, and vidir opens the directory in an editor where each line is a file, including subdirectories. edir and edmv extend the same pattern to copy and move operations as well as rename, so you can do a multi-file reorganisation by editing one buffer. pipe-rename reads filenames from standard input, hands them to your editor, and renames whatever the editor writes back.
A quick map of which editor-driven tool does what:
vimv: opens a file list in Vim; commit on savemassren: same idea, uses$EDITORinstead of Vimvidir: lists directory contents, including subdirectories, in your editormmv: takes a Perl-style rename expression, previews the result before applyingedir: editor-driven rename, copy, and move in one toolpipe-rename: reads filenames from stdin, writes renames back to stdout
The honest tradeoff with editor-driven tools is speed. For a 30-file cleanup, they are faster than thinking up the regex. For a 3000-file batch with a clear pattern, you want a template-based tool instead.
The regex and template tools: when the rule is clear
Once the renaming rule fits on one line, you want a tool that takes the rule and applies it. This is the largest group in the list, and most of the tools here are written by people who wanted one specific feature the others did not have.
rename is the oldest and most universally available. It is the Perl rename script that ships with Debian-family distributions, and it takes a Perl substitution expression directly on the command line. rename-cli is a Rust rewrite of the same idea with a more modern flag set. F2 is a Go-based modern tool (Go is a compiled language known for shipping single static binaries) that supports configurable expressions for matching and replacing, which makes it the right choice when the rule is too gnarly for a one-liner Perl substitution. brename and brn2 (a fork of brename) emphasise safe operation, which is the difference between a useful script and an incident report.
tempren and renux are template-first. tempren takes a filename template with placeholders (date, counter, original name, regex captures) and writes the result, which is the right tool for generating structured names like 2026-08-14-vacation-{counter}.jpg from a folder of phone dumps. renux adds regex, placeholders, and text transformations in the same binary. nomino is the developer-oriented choice: it understands hashes, regex captures, and counter patterns, and it is the right tool when you are renaming a generated folder of build artifacts.
If you are doing any non-trivial rename and you want a safety net, this is the group to start in. The preview-then-apply tools (brename, F2 with --dry-run) are the ones I reach for when the rename is irreversible.
The TUI tools: when you want a visual picker
Some renamers give you a full-screen interface rather than a one-shot command. You see the proposed names, you confirm or skip each one, and the tool commits the rename when you are done. These are the right tools when the rename is interactive in nature: sorting photos into event folders, applying different naming rules to different subsets, or doing a cleanup that involves judgement calls on each file.
RnR is the simplest of this group: it shows you files, you edit the names in place, and it commits on save. regname is a heavier ncurses (a library that lets terminal applications draw a full-screen interface) interface that gives you a multi-pane view with regex preview. Bren and Renamer sit between the two: they are TUI tools, but with more options for batch operations and plugin support respectively. Renamer in particular is worth noting for its plugin system: you can write a Python or shell plugin to add a new transformation, which makes it the right tool when the built-in operations do not cover your case.
The tradeoff with TUI tools is that they are harder to script. If you are doing the same rename every week, you want a command-line tool you can put in a shell script. If you are doing a one-off cleanup with judgement calls, the TUI tools save more time than they cost.
The pipe-friendly tools: when the rename is part of a pipeline
A few renamers are designed to be the last stage of a shell pipeline. You generate a list of source and target names upstream, you pipe it in, and the tool does the rename. This is the right shape when you are combining the renamer with find, fd, or a custom script that decides what each file should be called.
ren takes find-formatted lines on standard input and renames them, which means you can do find . -name '*.jpeg' | ren 's/jpeg/jpg/' and get the rename without intermediate files. renameutils is actually five small programs (qmv, qcp, imv, icp, deurlname) that all follow the same editor-driven pattern but accept piped input as well. moove adds file move and copy to the rename toolkit, which is useful when you are reorganising files into new directories as part of the rename.
If your renames follow naturally from a find or fd query, the pipe-friendly tools are faster than the editor-driven tools because you skip the buffer step.
Trade-offs
Picking one tool and learning it well is almost always faster than installing five tools and switching between them. For most people, F2 or rename covers the regex/template cases, vimv covers the editor-driven cases, and the rest of the list is specialised. Installing the whole set adds maintenance cost you do not need.
The renamers in this list are mostly written by one or two people as side projects. That does not mean they are broken, but it does mean you should test them on a copy of your folder before running them on the real one. A quick GitHub check on the last commit date of whichever tool you plan to install is worth the two minutes.
If your rename is small enough to do by hand and you only have a handful of files, you do not need any of these. A for loop in bash is fine. The threshold where a renamer starts paying for itself is somewhere around ten files, and it climbs fast as the rule gets more complex.
Bottom line
If you only install one tool from this list, install F2. It is cross-platform, it is fast, it supports a real expression language for the rename rule, and it has a clean preview mode. For the editor-driven case, add vimv. That covers maybe eighty percent of what you would ever want to do from the terminal, and the other tools in this article are for the remaining twenty percent. If you find yourself installing more than three of these, you are probably looking for a graphical file manager instead.
