Como posso adicionar espaços entre minhas saídas usando o sed / echo ou qualquer outro comando no linux?

Meu script o / p:

cat /tmp/test.txt | while read in; do echo -en '\n';  ./ovm_vmdisks -u admin -p xxxxxx -h localhost -v "$in"; done |  sed "s/'//g" | egrep -i "Virtual Machine|Virtual Disk|Physical Disk" |sed "s/://g" > /tmp/Automated/Virtualmachines_DETAILS.txt; cat /tmp/Automated/Virtualmachines_DETAILS.txt

Answer 1

Tente isto:

sed '2,$s/^Virtual Machine/\n&/' file

    

Answer 2

Escreva e esvazie o eco onde você deseja que a nova linha

Por exemplo

echo Foo
echo
echo Bar

Resultados em ...

Foo

Bar
