如何使用 sed/echo 或 Linux 中的任何其他命令在输出之间添加空格？

首选输出：

Virtual Machine  Test01 status  Running.
Virtual Disk  Test01 size  61GB
Physical Disk  HITACHI (170)
Physical Disk  HITACHI (171)
Physical Disk  HITACHI (172)

我的脚本 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

尝试这个：

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

答案2

在需要换行的地方写入并清空 echo

例如

echo Foo
echo
echo Bar

结果是...
