Ranger - Terminal Tooling

For a tool that touts "VI key bindings", no one should be surprised at the basic file and directory navigation keys: h, j, k, and l. j moves the selection in the center column one item down. k moves one item up. l will either move into the directory of the selection, or open the file of the selection by using your configured $EDITOR. gg moves the cursor to the first item in the directory, G moves it to the bottom.

Moving around with h, j, k, and l allows you to fly around your file system, and the three-column view gives you a quick view of not only what's in the current directory, but also both what's in the parent directory and child directory.

If this was all ranger could do, it would already be a fairly handy, albeit limited use tool (it also wouldn't really be a full 'file manager' in that case either). Ranger handles much more however.

Ranger takes the "VI bindings" much further than simple movement. Want to copy a file? Hit yy (the letter y, hit twice) to copy the file into a temporary register, then in the destination of your choice, hit pp to paste the file. Deleting is much the same; just hit dd to delete your file. To move a file, you just delete dd but then paste it pp wherever you want.

Change your mind about deleting a file before pasting? Hit u to undo the delete. Want to copy multiple files? Hit Space over all the files you want to copy (they should be marked with a different color and be indented slightly to show they're selected), then use yy and pp as before only this time, all the selected files will be copied/pasted.

In this example, app.go, db.go, Dockerfile, and main.go are selected (but not tracing.go). When you mark a file, the highlighted line is automatically moved to the next item (so you can just hit Space Space Space and select consecutive items), but it is not included in the multiple selection.

So far, the mechanism to move a file does not allow for renaming it (it is just copied and pasted without changing anything). How do you rename a file then? Like in vim, there's multiple ways to edit a file name (analogous to a word in vim). To completely change the file name, you can hit cw (change word, in vim language). This gives you a blank text input area to rename the file to whatever you want. If you only wanted to change the basename of the file, you can hit a, and the rename prompt field will be pre-populated with the file and the cursor will be on the . file just before the extension.

If you want to change the extension (or just want to have the whole file name pre-populated so you can change whatever you want), hit A and the cursor will be at the very end of the file name in the prompt.

And lastly if you want to prefix something in front of the file name, you can hit I to pre-populate with the file and the cursor at the front.

But what if you have a bunch of files to rename, and you may or may not want to rename them differently? What if you want to make the same change to each file name?

After highlighting the files you're interested in, type :bulkrename (ranger offers tab completion so you can just type :b<TAB> and the rest will be filled in for you). A temporary file will be spun up with each of the file names you selected. You can use the full power of your editor to rename the files however you want.

When you exit the file, another temp file will be conjured up giving you a preview of the shell commands it will run (using mv). You have one last chance to change things (like changing the destination directory the files will be renamed/moved to). After saving, ranger will execute the rename.
