使用 awk 或 sed 将文件中的特定行移动到另一行的 Bash 脚本？

Question

我看到这里得到了回答:
Moving matching lines in a text file using sed
和这里:
How to move specified line in file to other place with regexp match (bash script)?
但是我在为我的案例实现它时遇到了问题。
我有一个 .csv 文件，其中包含:

Unit Tests
Model: A
Tue Sep  8 22:52:24 MDT 2020
User: br
Files Used:
    DATA FILE - /path/to/file/data.txt
    TEST TARBALL - /path/to/tarball/my_test.tar.bz2

Results:

Module,Test Suite,Total Tests,Tests Passed,Tests Failed,Pass Rate

Individual Test Run,ClientTests,15,15,0,100.00%
,GraphTests,37,26,11,70.00%

Mean Pass Rate for All Tests,,52,41,11,78.85%

我需要移动:

Mean Pass Rate for All Tests,,52,41,11,78.85%

一直到“结果”下方。所以它看起来像这样:

Unit Tests
Model: A
Tue Sep  8 22:52:24 MDT 2020
User: br
Files Used:
    DATA FILE - /path/to/file/data.txt
    TEST TARBALL - /path/to/tarball/my_test.tar.bz2

Results:
Mean Pass Rate for All Tests,,52,41,11,78.85%

Module,Test Suite,Total Tests,Tests Passed,Tests Failed,Pass Rate

Individual Test Run,ClientTests,15,15,0,100.00%
,GraphTests,37,26,11,70.00%

不保证行号。 “使用的文件”部分可能包含更多文件。此外，根据正在运行的测试，可能还有其他“平均通过率”行。例如:

Unit Tests
Model: A
Tue Sep  8 22:52:24 MDT 2020
User: br
Files Used:
    DATA FILE - /path/to/file/data.txt
    TEST TARBALL - /path/to/tarball/my_test.tar.bz2
    CLIENT FILE - /path/to/other/file/client.txt

Results:

Module,Test Suite,Total Tests,Tests Passed,Tests Failed,Pass Rate

Individual Test Run,ClientTests,15,15,0,100.00%
,ClientVarTests,12,12,0,100.00%
,GraphTests,37,26,11,70.00%

Mean Pass Rate for Client Tests,,27,27,0,100.00%
Mean Pass Rate for All Tests,,64,53,11,82.81%

在我的脚本中，我尝试了 awk:

MEAN_PASS_ALL="Mean Pass Rate for All Tests"

awk '/${MEAN_PASS_ALL}/{t=$0;next}1;/RESULTS/{print t}' ${CSV_FILE}

然而，所做的只是打印出 .csv 文件内容并且没有移动该行:

$ ./parse_results.sh
Unit Tests

User: br
Files Used:
    DATA FILE - /path/to/file/data.txt
    TEST TARBALL - /path/to/tarball/my_test.tar.bz2

Results:

Module,Test Suite,Total Tests,Tests Passed,Tests Failed,Pass Rate

Individual Test Run,ClientTests,15,15,0,100.00%
,GraphTests,37,26,11,70.00%

Mean Pass Rate for All Tests,,52,41,11,78.85%

我也试过 sed，但出现错误:

sed "/.*Mean/d;/.*RESULTS/i"$(sed -n '/.*Mean/p' ${CSV_FILE})  ${CSV_FILE}

$ ./parse_results.sh
sed: can't read Pass: No such file or directory
sed: can't read Rate: No such file or directory
sed: can't read for: No such file or directory
sed: can't read All: No such file or directory
sed: can't read Tests,,52,41,11,78.85%: No such file or directory

Individual Test Run,ClientTests,15,15,0,100.00%
,GraphTests,37,26,11,70.00%

看起来它删除了该行，但它没有将其打印到我想要​​的位置，也没有“保存”更改。
如果有不止一行包含“平均通过率”，我希望它们都移到“结果”的正下方:
我在这里做错了什么？如何移动文件中的行并将文件与更改一起保存？
谢谢!

Answer 1

您可以使用 2 pass:

awk 'FNR == NR {
   if ($0 ~ /^Mean Pass Rate /)
      mpr = mpr ORS $0
      next
}
/^Results:/ {
   $0 = $0 mpr
}
!/^Mean Pass Rate /' file file
