我有一个很大的输入，看起来像这样:

我想从$ 5列和$ 6列的第一张表中打印一列数字.我想对第11、15和20行上的数字应用算术运算，并打印这些结果而不是表中的数字.我有一个代码:
BEGIN { CONVFMT="%0.17f" }
/D Format/ { exit }
$1 == 9 { prt(1,1) }
$1 == 10 { prt(1,1) }
$1 == 11 { prt(180,3.141592653589) }
$1 == 15 { prt(100,1) }
$1 == 16 { prt(1,1) }
$1 == 20 { prt(10,1) }
$1 == 23 { prt(1,1) }
$1 == 24 { prt(1,1) }
$1 != 26 { prt(1,1) }
function prt(mult, div) {
print trunc($5 * mult / div) ORS trunc($6 * mult / div)
}
function trunc(n, s) {
s=index(n,".")
return (s ? substr(n,1,s+6) : n)
}
我想得到一个输出:
43.685030
0.106608
0.080182
0.000675
156.68965
0.657068
21.935614
0.176999
83.864830
0.115873
22.502499
0.047924
3.936308
0.005290
7.491860
0.009210
但是我两次获得这些编号，但文件中没有很好的限制区. 所以我的问题是: 1)如何只打印一张表格中的数字.我的意思是这16个数字:
$1 == 9 { prt(1,1) }
$1 == 10 { prt(1,1) }
$1 == 11 { prt(180,3.141592653589) }
$1 == 15 { prt(100,1) }
$1 == 16 { prt(1,1) }
$1 == 20 { prt(10,1) }
$1 == 23 { prt(1,1) }
$1 == 24 { prt(1,1) }
2)如何限制程序应该在字符串/F Format/到/D Format/之间使用表的区域? 非常感谢.
编辑代码
BEGIN { CONVFMT="%0.17f" }
/D Format/ { exit }
$1 == 9 { prt(1,1); next }
$1 == 10 { prt(1,1); next }
$1 == 11 { prt(180,3.141592653589); next }
$1 == 15 { prt(100,1); next }
$1 == 16 { prt(1,1); next }
$1 == 20 { prt(10,1); next }
$1 == 23 { prt(1,1); next }
$1 == 24 { prt(1,1); next }
$1 != 26 && $1 + 0 > 0 { prt(1,1); next }
function prt(mult, div) {
print trunc($5 * mult / div) ORS trunc($6 * mult / div)
}
function trunc(n, s) {
s=index(n,".")
return (s ? substr(n,1,s+6) : n)
}
输出重复的问题是由于单行同时匹配其自身的编号和$1 != 26条件.一个简单的解决方案是在每个prt(…)调用之后添加; next.
零输出的问题同样是由于$1 != 26匹配太多.例如，您可以在此行中添加其他条件(例如$1 != 26 && $1 + 0 > 0).
这些更改应产生所需的输出.除此之外，该脚本还有很多可以优化的冗余(例如，所有{ prt(1,1); next }行都可以合并为条件更复杂的一条)，但是对于一次性脚本而言，这可能不值得. /p>
例如，对于此示例，这可能是一组完整的图案线:
/D Format/ { exit }
!($1 ~ /^[1-9]/) { next }
$1 == 26 { next }
$1 == 11 { prt(180,3.141592653589); next }
{ prt(1,1) }
I have a large input which part looks like:

I would like to print a column of numbers from the first table from column $5 and $6. I would like to applicate an arithmetic operations for numbers on rows 11, 15 and 20 and print these results instead of number in the table. I have a code:
BEGIN { CONVFMT="%0.17f" }
/D Format/ { exit }
$1 == 9 { prt(1,1) }
$1 == 10 { prt(1,1) }
$1 == 11 { prt(180,3.141592653589) }
$1 == 15 { prt(100,1) }
$1 == 16 { prt(1,1) }
$1 == 20 { prt(10,1) }
$1 == 23 { prt(1,1) }
$1 == 24 { prt(1,1) }
$1 != 26 { prt(1,1) }
function prt(mult, div) {
print trunc($5 * mult / div) ORS trunc($6 * mult / div)
}
function trunc(n, s) {
s=index(n,".")
return (s ? substr(n,1,s+6) : n)
}
I would like to get an output:
43.685030
0.106608
0.080182
0.000675
156.68965
0.657068
21.935614
0.176999
83.864830
0.115873
22.502499
0.047924
3.936308
0.005290

but I am getting these number twice and I haven't got good restricted area in file. So my questions are: 1) How to print numbers from tables only one times. I mean this 16 numbers:
$1 == 9 { prt(1,1) }
$1 == 10 { prt(1,1) }
$1 == 11 { prt(180,3.141592653589) }
$1 == 15 { prt(100,1) }
$1 == 16 { prt(1,1) }
$1 == 20 { prt(10,1) }
$1 == 23 { prt(1,1) }
$1 == 24 { prt(1,1) }
2) How to restict an area that the program should works with table between strings /F Format/ to /D Format/? Thank you very much.
Eddited code
BEGIN { CONVFMT="%0.17f" }
/D Format/ { exit }
$1 == 9 { prt(1,1); next }
$1 == 10 { prt(1,1); next }
$1 == 11 { prt(180,3.141592653589); next }
$1 == 15 { prt(100,1); next }
$1 == 16 { prt(1,1); next }
$1 == 20 { prt(10,1); next }
$1 == 23 { prt(1,1); next }
$1 == 24 { prt(1,1); next }
$1 != 26 && $1 + 0 > 0 { prt(1,1); next }
function prt(mult, div) {
print trunc($5 * mult / div) ORS trunc($6 * mult / div)
}
function trunc(n, s) {
s=index(n,".")
return (s ? substr(n,1,s+6) : n)
}
The problem of duplicate outputs is due to a single line matching both its own number and the $1 != 26 condition in the end. A simple solution is to add ; next after each prt(…) call.
The problem with zero outputs is likewise due to the $1 != 26 matching too much. You could, for example, add additional conditions to this line (such as $1 != 26 && $1 + 0 > 0).
These changes should produce the desired output. Other than that, the script has a lot of redundancy that could be optimised (e.g., all the { prt(1,1); next } lines could be merged into one with a more complex condition), but that may not be worthwhile for a one-off script.
edit: For example, this could be a complete set of pattern lines for this example:
/D Format/ { exit }
!($1 ~ /^[1-9]/) { next }
$1 == 26 { next }
$1 == 11 { prt(180,3.141592653589); next }
{ prt(1,1) }
