Configuration files with dash are ignored

[tkzv]

If configuration file is set in the command line with "-c" option and the file name contains a dash (hyphen, minus sign) "-", Traefik will use the default configuration. It fails silently, with no messages that the file was ignored; it's only noticeable by its behaviour.

For example,

./traefic -c config.toml 

correctly loads the configuration in config.toml, but

./traefic -c config-2.toml 

uses default settings and ignores the configuration file.

Observed in the latest 2.0.0 alpha in Windows and Linux:

$ ./traefik version
Version:      2.0.0-alpha1
Codename:     faisselle
Go version:   go1.12.1
Built:        2019-03-18T14:26:35Z
OS/Arch:      linux/amd64

>traefik.exe version
2019/03/21 13:51:55 Using high precision timer
Version:      2.0.0-alpha1
Codename:     faisselle
Go version:   go1.12.1
Built:        2019-03-18T14:40:53Z
OS/Arch:      windows/amd64

Example configuration:

[global]
sendanonymoususage = false

If the configuration file is called "config-2.toml", there will be a message "You haven't specify the sendAnonymousUsage option, it will be enable by default."

Workaround:

./traefik --configfile=config-2.toml

works correctly

hello, when you have a value that contains a hyphen, you have to add quotes around the value.

./traefik --config="config-2.toml"

It fails silently,

PS: could you follow the issue template.

PS: could you follow the issue template.

Do you want me to rewrite the bug with the template?
P.S. ./traefic -c "config-2.toml" and ./traefic -c 'config-2.toml' don't work either.

Sorry it's:

./traefik --config="config-2.toml"

[tkzv]

I wrote above that --config= works even without quotes. The bug is that -c does not work with dashes. Regardless of the quotes.

[ldez]

yes short flag doesn't works with dash, it's a standard behavior.

[tkzv]

Why? Never seen anything like that.
