No matter what any launcher command “`./launcher * app`” exits with “`ERROR: Config name must not contain upper case characters, spaces or special characters. Correct config name and rerun ./launcher.`”
I always have to comment “`exit 1`” in this condition… it’s quite annoying…

Can you post one concrete call to `launcher` that does this for you?

All calls does it:
```
./launcher bootstrap app
./launcher start app
./launcher enter app
./launcher rebuild app
```
The following trimmed script does it too:
```plaintext
#!/bin/bash
re='[A-Z/ !@#$%^&*()+~`=]'
if [[$1 =~ $re]];
then
echo "ERROR: Config name must not contain upper case characters, spaces or special characters. Correct config name and rerun $0."
fi
```

I believe condition is somehow case insensitive however `shopt nocasematch` is disabled.
I tried it on clean ubuntu 14.04.3

I’ve got same problem when testing docker on Ubuntu 14.04.4
```
root@og:/var/discourse# lsb_release -a
Description: Ubuntu 14.04.4 LTS
root@og:/var/discourse# ./launcher rebuild app
ERROR: Config name must not contain upper case characters, spaces or special characters. Correct config name and rerun ./launcher.

The problem is related to locale.
Everything works as expected until I change the locale.
Try execute this before launcher:
```plaintext
locale-gen sk_SK.UTF-8
export LANG=sk_SK.UTF-8
```

I had this same problem on CentOS7
```
localectl set-locale LANG=en_US.utf8
```
I do this and still don’t work. I have no idea what can i do now? Some ideas?

Did you also `export LANG=en_US.utf8` before running it? The current shell could have it’s own independent idea of locale.
As a separate matter, the test could be rewritten to be less locale sensitive:
```plaintext
#!/bin/bash
re='[^abcdefghijklmnopqrstuvwxyz0123456789_.-]'
if [[$1 =~ $re]];
then
echo "ERROR: Config name must not contain upper case characters, spaces or special characters. Correct config name and rerun $0."
fi
```
But maybe people wanted `[configname]` to work…
