从文件中提取行块时，我遇到了一些问题。考虑以下两个文件

File-1
1.20/abc/this_is_test_1
perl/RRP/RRP-1.30/JEDI/JEDIExportSuccess2
exec perl/RRP/RRP-1.30/JEDI/CommonReq/confAbvExp
perl/LRP/BaseLibs/close-MMM
exec perl/LRP/BaseLibs/launchLRPCHURRTA("TYRE")
this/or/that

File-2
exec 1.20/setup/testird
exec 1.20/sql/temp/Test3

exec perl/LRP/LRP-classic-4.14/churrip/chorSingle

exec perl/LRP/SetupReq/abcDEF
exec perl/BaseLibs/launch_client("sqlC","LRP")
exec perl/LRP/LRP-perl-4.20/fireTrigger

现在对于 File-1 中的每一行，我想从 File-2 中提取相关的行块。File-2 中的块定义如下

exec 1.20/setup/xxxxx
blah blah blah
blah blah blah
.
.
.
all lines till next setup line is found

例如

exec 1.20/setup/testinit
exec 1.20/abc/this_is_test_1
exec 1.20/abc/this_is_test_1

或者

exec perl/LRP/SetupReq/xxxxx
blah blah blah
blah blah blah
.
.
.
all lines till next setup line is found

例如

exec perl/LRP/SetupReq/testird_LRP("LRP")
exec perl/BaseLibs/launch_client("LRP")
exec perl/LRP/LRP-classic-4.14/churrip/chorSingle
exec perl/LRP/BaseLibs/setupLRPMMMTab

#PAUSE Expand Churrip tree view & open all nodes
exec perl/LRP/LRP-classic-4.14/Corrugator/multipleSeriesWeb
exec perl/BaseLibs/ShutApp("Self Destruction System")
exec perl/LRP/BaseLibs/close-MMM

到目前为止，我已经设法在以下脚本的帮助下从 File-2 中提取了相关块

Shell Script
#set -x

TEMPDIR="/usr/tmp/tempBatchDir"
rm -rf $TEMPDIR/*

createBatch ()
{

do
        if [ ! -s $CPBATCHFILE ]; then
                echo "$CPBATCHFILE is empty" >> $LOGFILE
                STATUS=0
        fi
        awk '/[Ss]etup.*[Tt]est/ || /perl\/[[:alpha:]]*\/[Ss]etup[rR]eq/{if(b) exit; else b=1}1' $CPBATCHFILE > $TESTSETFILE
        grep -i "$TESTNAME$" $TESTSETFILE >> $LOGFILE 2>&1
        if [ $? -eq "0" ]; then
                echo "test found" >> $LOGFILE
                cat $TESTSETFILE >> $FAILEDBATCH
                FOUND=1
        fi
        TSTFLLINES=`wc -l < $TESTSETFILE`
        CPBTCHLINES=`wc -l < $CPBATCHFILE`
        DIFF=`expr $CPBTCHLINES - $TSTFLLINES`
        tail -n $DIFF $CPBATCHFILE > $DIFFFILE
        mv $DIFFFILE $CPBATCHFILE
done

if [ $FOUND -eq 0 ]; then
        echo $TESTNAME > $TEMPDIR/test.txt
        ABSTEST=$(echo $TESTNAME | sed 's/\\//g')
        echo "FATAL ERROR: Test \"$ABSTEST\" not found in batch" | tee -a $LOGFILE
fi

}

        createBatch $fltest
done

sed -i 's/\//\\/g' $FAILEDBATCH
## Clean up
cp $FAILEDBATCH .

这个脚本的问题是

  1. 为 File-1 的每一行遍历 File-2 需要一些时间。我想知道是否有更好的解决方案，我只需要遍历 File-2 一次。

  2. 该脚本确实解决了我的问题，但我留下了其中包含重复行块的文件。我想知道有没有办法删除重复的行块。

这是我执行脚本时的输出

exec 1.20\setup\testinit
exec 1.20\abc\this_is_test_1
exec 1.20\abc\this_is_test_1

exec perl\LRP\BaseLibs\close-MMM

我尝试通过网络搜索我的答案，但找不到适合我需求的答案。

给定 File-1 和 File-2 这是我期望我的脚本输出的内容（我已经列出了我期望 FILE-1 中每一行的输出）

For line "1.20/abc/this_is_test_1" in FILE-1
Output
exec 1.20/setup/testinit
exec 1.20/abc/this_is_test_1
exec 1.20/abc/this_is_test_1

For line "perl/RRP/RRP-1.30/JEDI/JEDIExportSuccess2" in FILE-1
Output
exec perl/RRP/SetupReq/testdef_ijk
exec perl/RRP/RRP-1.30/JEDI/SetupReq/confAbvExp
exec perl/RRP/RRP-1.30/JEDI/JEDIExportSuccess2

For line "exec perl/RRP/RRP-1.30/JEDI/CommonReq/confAbvExp" in FILE-1
Output
do nothing as there is no line matching this is in FILE-2

For line "perl/LRP/BaseLibs/close-MMM" in FILE-1
Output
exec perl/LRP/SetupReq/testird_LRP("LRP")
exec perl/BaseLibs/launch_client("LRP")
exec perl/LRP/LRP-classic-4.14/churrip/chorSingle
exec perl/LRP/BaseLibs/setupLRPMMMTab
exec perl/LRP/BaseLibs/launchMMM
exec perl/LRP/BaseLibs/launchLRPCHURRTA("TYRE")
#PAUSE Expand Churrip tree view & open all nodes
exec perl/LRP/LRP-classic-4.14/Corrugator/multipleSeriesWeb
exec perl/BaseLibs/ShutApp("Self Destruction System")
exec perl/LRP/BaseLibs/close-MMM    

For line "exec perl/LRP/BaseLibs/launchLRPCHURRTA("TYRE")" in FILE-1
Output
Do nothing as it would generate the same black as line "perl/LRP/BaseLibs/close-MMM" in FILE-1 did

For Line "this/or/that" in FILE-1
Output
Do nothing as there is no line matching this is in FILE-2

所以我的最终输出应该类似于（块的顺序无关紧要）

exec 1.20/setup/testinit
exec 1.20/abc/this_is_test_1
exec 1.20/abc/this_is_test_1

exec perl/RRP/SetupReq/testdef_ijk
exec perl/RRP/RRP-1.30/JEDI/SetupReq/confAbvExp
exec perl/RRP/RRP-1.30/JEDI/JEDIExportSuccess2

exec perl/LRP/SetupReq/testird_LRP("LRP")
exec perl/BaseLibs/launch_client("LRP")
exec perl/LRP/LRP-classic-4.14/churrip/chorSingle
exec perl/LRP/BaseLibs/setupLRPMMMTab
exec perl/LRP/BaseLibs/launchMMM
exec perl/LRP/BaseLibs/launchLRPCHURRTA("TYRE")

exec perl/LRP/LRP-classic-4.14/Corrugator/multipleSeriesWeb
exec perl/BaseLibs/ShutApp("Self Destruction System")
exec perl/LRP/BaseLibs/close-MMM

如果有人能给我一些关于如何进行的指示，那就太好了。是的，我忘了提，这不是作业问题:-)。

非常感谢

以下假设“设置”行对于每个块都是唯一的。我们将此行用作关联数组的键，该数组跟踪我们已经打印了哪些块。

脚本的第一行将第一个文件读取到一个名为的变量中，该变量从第一个文件regex中收集我们想要匹配的行（成语NR==FNR表示当当前文件的行号等于收集的所有文件的行号时，即是，只有当我们从参数列表中读取第一个文件时才是真的）。我希望脚本的其余部分相当简单。

awk 'NR==FNR { gsub(/\//,"\\/"); regex = regex sep $0; sep = "|" ; next}
    /[Ss]etup/ { label = $0; printing = 0; collected = nl = "" }
    { collected = collected nl $0; nl=RS }
    $0 ~ regex { if(!printed[label]) {
        printed[label] = printing = 1; print collected } }
    printing { print }' File-1 File-2

如果“设置”行不一定是唯一的，也许您可​​以使用值collected作为键。

这应该（我希望）对File-1匹配中相同块的多行具有鲁棒性File-2。

我知道我sed在评论中暗示了一个解决方案，但事实证明这是一种awk感觉更自然的问题。当然，它也可以用 Perl 或 Python 或您拥有的任何东西来完成。

如果行顺序无关紧要，您可以通过命令提示符以这种方式从文件中删除重复项：

sort filename | uniq

为了找出这两个文件中存在哪些行，我使用了一个创建散列（或关联数组，如果你愿意的话）的 perl 脚本。然后我扫描文件 A，将每一行添加到哈希中，使用该行作为键，并将值设置为 1。然后我对文件 A 做了同样的事情，但将值设置为 2，如果键已经存在，我加了 2 个。结果将只遍历每个文件一次，最后我知道如果密钥的值为 1，它只存在于文件 A 中，如果它的值为 2，它只存在于文件 B 中，并且如果它的值为 3，则它存在于两者中。

编辑： 我在一个项目中发现了一些 perl 代码，完全按照我上面描述的方式。在这段代码中，我只关注差异，但应该很容易根据您的需要修改它

my %found;
foreach my $item (@qlist) { $found{$item} += 2 };
foreach my $item (@xlist) { $found{$item} += 1 };

foreach my $found (keys(%found))
{
  if    ($found{$found} == 3)
  {
    # It's in both files. Not doing anything.
  }
  elsif ($found{$found} == 2)
  {
    print "$found found in the QC-list, but not the x-list.\n";
  }
  elsif ($found{$found} == 1)
  {
    print "$found found in the x-list, but not the QC-list.\n";
  }
}

感谢@tripleee 和@Jarmund 的建议。从您的输入中，我终于能够找出我的问题的解决方案。我从关联数组中得到了为每个块创建唯一键的提示，所以这就是我所做的

  • 取 file-2 并将每个块转换为单行

    awk '/[Ss] 设置。[Tt]测试/|| /perl/[[:alpha:]] /[Ss]etup[Rr]eq/{if(b) 退出；否则 b=1}1' file-2 > $TESTSETFILE cat $TESTSETFILE | sed ':a;N;$!ba;s/\n//g;s/ //g' >> $SINGLELINEFILE

  • 现在这个文件中的每一行都是一个唯一的条目

  • 在此之后，我对 File-1 中的每一行使用 grep 并现在找到相应的块（转换为单行）
  • 然后我使用 awk 或 sort -u 在我的解决方案文件中查找唯一条目

也许这个解决方案不是最好的，但它比前一个要快得多。

这是我的新脚本

FLBATCHLIST=$1
BATCHFILE=$2

TEMPDIR="./tempBatchdir"
