使用通配符删除文件

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?

Answer 1

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)
    }
}
