BASH 2模式之间按字母顺序排序线 [英] BASH sort alphabetically lines between 2 patterns

问题描述

我想按字母顺序排序仅2模式之间的线/ ^ BLE BLE BLE /和/ ^ CCC DDD EEE /。重要的是，我要离开休息线完整（不排序）。

I'd like to sort alphabetically only lines between 2 patterns /^ble ble ble/ and /^ccc ddd eee/. Important thing is that I want to leave rest lines intact ( not sorted ).

例CFG文件：

123 345
678 901
bla bla bla
ble ble ble
crypto isakmp key 6 CCCCCC address 123.456.789.004
crypto isakmp key 6 AAAAAA address 123.456.789.005
crypto isakmp key 6 XXXXXX address 123.456.789.003
crypto isakmp key 6 BBBBBB address 123.456.789.001
ccc ddd eee
fff ggg hhh iii
123 456

期望的输出：

123 345
678 901
bla bla bla
ble ble ble
crypto isakmp key 6 AAAAAA address 123.456.789.005
crypto isakmp key 6 BBBBBB address 123.456.789.001
crypto isakmp key 6 CCCCCC address 123.456.789.004
crypto isakmp key 6 XXXXXX address 123.456.789.003
ccc ddd eee
fff ggg hhh iii
123 456

preferred工具AWK和单行。将是很好，如果解释附会。

Preferred tool is AWK and "one-liner". Would be nice if explanation will be attached.

推荐答案

这是使用的 ASORT（） 以按GNU AWK数组：

This is a perfect case to use asort() to sort an array in GNU awk:

gawk '/^ble/ {f=1}
     /^ccc ddd eee/ {f=0; n=asort(a); for (i=1;i<=n;i++) print a[i]}
     !f
     f{a[$0]=$0}' file

本采用了类似的逻辑如何选择两个标记模式之间的线，可以使用awk / SED 出现多次通过加入，即：

This uses a similar logic as How to select lines between two marker patterns which may occur multiple times with awk/sed with the addition that it:

• 此范围之外的打印线


• 此范围内的房屋线


• 当档已经结束，排序和打印他们。

详细说明：

• / ^ BLE / {F = 1}找到先从 BLE A线的时候，就设置一个标志


• / ^ CCC DDD EEE / {F = 0; N = ASORT（一）;对于（i = 1; I＆LT; = N;我++）打印[I]}发现开始 CCC DDD EEE A线的时候，设置该标志关闭。此外，排序的数组 A [] 包含该范围内的所有线路，并打印出来。


• ！˚F如果标志是关闭（即超出范围），使该行打印，评估为true。


• ˚F{a [$ 0] = $ 0} 如果标志是，存储阵列中的行 A [] ，以便其信息可以在以后使用。

• /^ble/ {f=1} when finding a line starting with ble, set a flag on.
• /^ccc ddd eee/ {f=0; n=asort(a); for (i=1;i<=n;i++) print a[i]} when finding a line starting with ccc ddd eee, set the flag off. Also, sort the array a[] containing all the lines in the range and print them.
• !f if the flag is off (that is, outside the range), evaluate as True so that the line is printed.
• f{a[$0]=$0} if the flag is on, store the line in the array a[] so that its info can be used later on.

$ gawk '/^ble/ {f=1} /^ccc ddd eee/ {f=0; n=asort(a); for (i=1;i<=n;i++) print a[i]} !f; f{a[$0]=$0}' a
