Bash 代码每 4 行拆分一次，然后合并

也许我的标题并不能完全说明我的意图。我有一个如下所示的数据列表：

我们可以看到第一行和第五行都是头/名称，但以 #0/1 或 #0/2 结尾。现在我希望每 4 行进行分组，但稍后将所有带有 #0/1 的行合并在一起，然后将 #0/2 合并在一起。

应该是这样的：

@HWI....#0/1
TTCCGC
+
cffccc
@HWI....#0/1
CCGGGG
+
abbcgg
....

另一个文件是： @HWI...#0/1 ATTCCG + FCCFCC @HWI...#0/1 CGCCGG + gbbcaa

我知道如何用一个简单的 python 脚本来做到这一点。但只是想知道我们是否只能使用一些非常简单的 bash 代码？谢谢

Maybe my title cannot fully explain my intention.
I have a list of data like below:

@HWI-ST150_0129:3:8:21208:93107#0/1

We can see the first line and 5th line are both head/name, but ending with either #0/1 or #0/2. Now I hope to group every 4 lines, but later merge all those with #0/1 together, and #0/2 together.

Should be like:

@HWI....#0/1
TTCCGC
+
cffccc
@HWI....#0/1
CCGGGG
+
abbcgg
....

also another file is:
@HWI....#0/1
ATTCCG
+
fccfcc
@HWI....#0/1
CGCCGG
+
gbbcaa

I know how to do this with a simple python script. But just wondering if we can do only with some quite simple bash code?
Thanks

sed -n '1,${p;n;n;n;}' 应该可以获取每第四行：

[ 11:32 [email protected] ~/SO/bash ]$ cat blah | sed -n '1,${p;n;n;n;}'
@HWI-ST150_0129:3:8:21208:93107#0/1
@HWI-ST150_0129:3:8:21208:93107#0/2

用于 sed 的有用单行脚本
 man sed

sed -n '1,${p;n;n;n;}' should work for getting every 4th line:

[ 11:32 [email protected] ~/SO/bash ]$ cat blah | sed -n '1,${p;n;n;n;}'
@HWI-ST150_0129:3:8:21208:93107#0/1
@HWI-ST150_0129:3:8:21208:93107#0/2

[ 11:33 [email protected] ~/SO/bash ]$ cat blah
