Remove files with wildcard

Question

I am trying to delete files with a wildcard like shell scripts like:

c:\del 123_*

My trial as below was failed.

os.RemoveAll("/foo/123_*") os.Remove("/foo/123_*")

I guess I need to use some library to use a wildcard.
What is good practice for deleting files with a wildcard?

Read the directory, select the files wich match the desired pattern and Remove them. No library but some programming. — Volker

The wildcard * is a feature of the shell, not one of the file system. So you have to go through the list of files and test their names against a pattern. The regexp package can deal with complicated patterns, however strings.HasPrefix(str, prefix) can do the task at hand quite well. — Patrick Bucher

As people mentioned wildcard is a feature of shell (e.g. Windows cmd.exe) not OS and usually programming languages don't provide equivalent of del xyz*. You should use Glob function to find files you want to delete.

files, err := filepath.Glob("/foo/123_*") if err != nil { panic(err) } for _, f := range files { if err := os.Remove(f); err != nil { panic(err) } }
