Hi,
I found a bug when bash parsing brackets with version 5.0.3. Here are some
outputs:
root@server:~# bash -version
GNU bash, version 5.0.3(1)-release (x86_64-pc-linux-gnu)

root@server:~# echo [0-1]
1
root@server:~# echo [[[[[[[[[208174hkjdfsglh0-13984jf0]
1
When I use a old version bash, it's ok:
root@server2:~# bash -version
GNU bash, version 4.4.12(1)-release (x86_64-pc-linux-gnu)
