局部排序求助

bikkuri

大家好！
我有一个问题向大家请教。
有以下一个文本，希望对连续的三行中有THRESHOLD、CRITICAL和CURRENT的行进行排序。
SERVER:         135.240.144.16
USER:           1ls
THRESHOLD:      100 G
CRITICAL:       50 G
CURRENT:        70.30 G (75488632832 Bytes) available
-----------------------------------------------------------------------------
SERVER:         135.240.146.254
USER:           1ls
THRESHOLD:      100 G
CRITICAL:       50 G
CURRENT:        426.59 G (458046586880 Bytes) available
-----------------------------------------------------------------------------
希望得到的结果是：
SERVER:         135.240.144.16
USER:           1ls
THRESHOLD:      100 G
CURRENT:        70.30 G (75488632832 Bytes) available
CRITICAL:       50 G
-----------------------------------------------------------------------------
SERVER:         135.240.146.254
USER:           1ls
CURRENT:        426.59 G (458046586880 Bytes) available
THRESHOLD:      100 G
CRITICAL:       50 G
-----------------------------------------------------------------------------
请问awk命令应该如何写呢？
谢谢大家！

<<<awk4.0+

1. awk '/^THRESHOLD/||/^CRITICAL/||/^CURRENT/{a[$2]=$0;next}/^-/{PROCINFO["sorted_in"]="@ind_num_desc";for(i in a){print a[i]};delete a}1' file

谢谢您的帮助。可是我的awk版本比较低，是3.1.7。

在这个awk版本下您的命令不能得到正确的结果。
请问应该如何修改才能在awk 3.1.7下得到正确的结果呢？
谢谢！

在数值没有重复值的情况下！

awk '/THRESHOLD|CRITICAL|CURRENT/{a[$1]=$2;b[$2]=$0;next}!/^-/{d[++t]=$0}/^-/{for(j=1;j<=t;j++) print d[j];for(i=asort(a,c);i>0;i--) print b[c];print $0;t=0}' file

1. awk '/^THRESHOLD/||/^CRITICAL/||/^CURRENT/{a[$0]=$2;b[$2]=$0;next}/^-/{d=asort(a,c);for(i=d;i>=1;i--){print b[c[i]]};delete a}1' file

复制代码

谢谢两位的帮助。
貌似wh7211君的命令可以得到正确结果，而zxy877298415君的命令出错了。
