zsh: no matches found: [:space:]

For some reason, in zsh, I'm unable to use the [:space:] pattern to match all whitespace.

ex. 

$ echo 'Welcome To Here' | tr [:space:] '\t'
zsh: no matches found: [:space:]

But if I do this in bash, then it works fine

$ echo 'Welcome To Here' | tr [:space:] '\t'
Welcome To  Here

Would this be some kind of problem in my ~/.zshrc, or does zsh not support this? I'm also using oh my zsh.

Solution

  • zsh sees the [:space:] and interpets it as a wildcard glob that will match a file named :, s, p, a, c or e. When there are no such files, it produces an error. So will bash with the failglob shell option enabled - your setup presumably turns it off somewhere. Just wrap it in quotes to prevent expansion:

    echo 'Welcome To Here' | tr '[:space:]' '\t'
