当我编写一条命令给我这样的输出时。
[root@localhost:~] esxcli storage filesystem list

现在我要所有以“ /”开头并以“：”代替空格的行
所以我尝试使用命令esxcli storage filesystem list | sed -e 's/\s\+/:/g' |awk '$1 ~ /^\/[a-z]+/ {print $1$2$3$4$5}和esxcli storage filesystem list |awk '$1 ~ /^\/[a-z]+/ {i=":";print $1i$2i$3i$4i$5i}'
这给了我这样的输出：
[root@localhost:~] esxcli storage filesystem list | sed -e 's/\s\+/:/g' |awk '$1 ~ /^\/[a-z]+/ {print $1$2$3$4$5}'

但是问题是，如果找不到卷名，那么它应该是“ ::”之类的东西。
我想要输出：
