Test if there are files matching a pattern in order to execute a script

8 answers

In bash, I have a directory that holds some file names that start with underscore _ and others that don't.

I want my script to check if a folder has any files that don't start with _. I write

if [[ -f $dir/[!_]* ]]
 then echo "There are unmarked files."
 else echo "All files marked."
fi

But when I run using a folder with files that do and do not start with _, the if statement has the opposite effect of what I intended. I list the entries in the folder that clearly display files without _, but the output keeps saying, All files marked.

What am I missing?

@muru ';' is not the same as + - perhaps you could perform an apples for apples test before commenting further - thanks
