Ubuntu中如何删除名称特殊的文件？ssh-keygen生成文件删除失败

Hey there, let's get rid of those oddly named files you ended up with after copying a command with extra newlines. Here are a few reliable methods to delete them:

1. First, figure out exactly what those filenames are #

Special characters like hidden newlines or carriage returns don't show up normally. Run one of these commands to see the escaped version of the filenames:

# Shows special characters as backslash escapes
ls -b

# Wraps filenames in quotes and escapes special chars
ls -Q

This will reveal if your file is something like $'\r' (a carriage return character), which is common when copying commands with unwanted line breaks.

2. Delete using the inode number (most foolproof method) #

Every file has a unique inode ID that lets you target it directly, no matter how weird the filename is:

1. Get the inode number of the problematic file:

   ls -i
   

   You'll see a numeric ID next to each filename (e.g., 12345 $'\r').
2. Use find to delete the file by its inode:

   find . -inum 12345 -delete
   

   Just replace 12345 with the actual inode number you found.

3. Delete using escaped special characters #

If you saw the filename is a carriage return (\r), you can delete it directly with this command:

rm $'\r'

Alternatively, you can input the carriage return manually: press Ctrl+V then Ctrl+M (this will show up as ^M in your terminal), then run:

rm '^M'

4. Use wildcards (with caution) #

If these weird files are the only non-standard ones in your directory, you can use a wildcard and confirm each deletion to avoid mistakes:

rm -i *

The -i flag will prompt you before deleting each file, so you can skip the ones you want to keep.

Why your original command didn't work #

Your command rm ''$'r' got interpreted as trying to delete a file named '$r', but your actual filename is a hidden carriage return character (\r), not the literal string $r. That's why you got the "No such file or directory" error.
