[SOLVED] How to make sort consider "_" in Bash?

Issue

I have a list of folders

$ ls -1 . 
_dns
linux
mariadb
minio
mongodb
nginx
_postgresdb
_python
_rabbitmq
redis
sphinx
supervisor
$

I would like to have them in the lexicographic order (the order provide by e.g. the vim sort):

$
_dns
_postgresdb
_python
_rabbitmq
linux
mariadb
minio
mongodb
nginx
redis
sphinx
supervisor
$

I don't succeed to do that with the unix sort:

$ ls -1 . | sort
_dns
linux
mariadb
minio
mongodb
nginx
_postgresdb
_python
_rabbitmq
redis
sphinx
supervisor
$

even with options:

$ ls -1 . | sort  -g
_dns
linux
mariadb
minio
mongodb
nginx
_postgresdb
_python
_rabbitmq
redis
sphinx
supervisor
$

$ ls -1 . | sort  -b
_dns
linux
mariadb
minio
mongodb
nginx
_postgresdb
_python
_rabbitmq
redis
sphinx
supervisor
$

$ ls -1 . | sort  -n
_dns
linux
mariadb
minio
mongodb
nginx
_postgresdb
_python
_rabbitmq
redis
sphinx
supervisor
$

Note: this question as been answered in a much better way in Unix sort treatment of underscore character

Solution

If you want a persistent solution you can export LC_COLLATE

$ ls -1  | sort

_dns
linux
mariadb
minio
mongodb
nginx
_postgresdb
_python
_rabbitmq
redis
sphinx
supervisor

$ export LC_COLLATE=C
$ ls -1  | sort

_dns
_postgresdb
_python
_rabbitmq
linux
mariadb
minio
mongodb
nginx
redis
sphinx
supervisor
