cat `-q` file (in linux) - passing operands that look like options


I have a file whose name is -q (It looks like this is made by accident)

I want to see it’s content, so I tried these

$ cat '-q'
$ cat "-q"
$ cat $'-q'

But nothing worked.(All gives same error cat: invalid option -- 'q')

Is there any way to see it’s content?


Solution

  • to create a file named -q do

    touch -- "-q"
    

    and to view its contents

    cat -- '-q' # Used single quotes to treat anything inside as literal characters
    

    should do it. -- means what follows should be treated as a positional parameter.


    Pls take time to look at @rici's [ answer ] which reminds some substle aspects regarding single vs double quotes.
