10.238.70.190
10.238.70.129

awk -F '[ :]+' '{print $(NF-1)}'

root@v210-2 # awk -F '[ :]+' '{print $(NF-1)}' 1

环境不同，我这里可以。

1. sed 's/[^0-9]*\([^:]\+\).*/\1/' 1

复制代码

cat file|awk -F"[: ]" '{print $6}
cat file|grep -oE "([0-9]{1,3}\.){3}[0-9]{1,3}"

tr -d "[a-zA-Z: ]" < 1 | sed 's/...$//'

我这边也是可以的。
[test@ver ~]$ awk -F '[ :]+' '{print $(NF-1)}' time
10.238.70.19
10.238.70.190
10.238.70.129
10.238.70.130
