How to remove unknown character from file name with terminal

[Kevin Tee]

Hello, I am new to linux, I have been trying to copy .pdf from my pc to external hard disk. But I got an error, I found that this weird character is the problem. I have search around for solution but the problem is that I don't know what character is it thus cannot remove. I tried to copy this weird character but unable to paste it. I can manually delete them, but there are too many. Also this character is visible only when renaming the file but invisible when not. Thank you.

I'm using linux mint cinnamon 17.1

Replace the unknown character with an asterisk.

For example, if I had a file called 'bad#file', and the '#' character were an unknown character, I would copy and rename it like this:

Code: Select all

cp /path/to/bad*file.pdf /path/to/destination/directory/good_file.pdf

If this doesn't work, here are some more complicated methods:

Thank you Buzzsaw for reply, but I have already manually rename all of them. Thanks anyway.
