No shell do Plano 9 rc, pode-se escrever
echo (foo bar baz)^.c
para obter
foo.c bar.c baz.c
ou
echo (foo bar baz)^(.c .h .o)
para obter
foo.c bar.h baz.o
Existe um equivalente a isso no Bash? Especificamente, existe uma maneira mais rápida do que
`for f in foo bar baz; do echo $f.c; done`
para o primeiro, e esse método existe para o último?
Atualmente, executo o Debian Buster no meu computador como teste. Agora que o Buster se tornou estável, como devo atualizar meu sistema?
Especificamente, como eu configuro /etc/apt/sources.list?
Atualmente, está assim:
# deb cdrom:[Official Debian GNU/Linux Live 9.9.0 xfce 2019-04-27T10:47]/ stretch main
# deb cdrom:[Official Debian GNU/Linux Live 9.9.0 xfce 2019-04-27T10:47]/ stretch main
deb http://ftp.uk.debian.org/debian/ buster main
deb-src http://ftp.uk.debian.org/debian/ buster main
deb http://security.debian.org/debian-security/ buster/updates main
deb-src http://security.debian.org/debian-security/ buster/updates main
#stretch-updates, previously known as 'volatile'
deb http://ftp.uk.debian.org/debian/ buster-updates main
deb-src http://ftp.uk.debian.org/debian/ buster-updates main
E quando eu executo sudo apt-get update, recebo esta saída:

Isso é bom? Estou particularmente preocupado com a mensagem do antigo estábulo. Eu deveria ter este repositório ainda?
