我想根据文件中的第4列(例如,16或18或5或7)对文本文件进行排序,但正如您所看到的,有些行没有该字段(例如:)在排序之后,它们应该低于它们最初的线以下。
示例数据

$r = mysqli_fetch_array($result); ?>

$resu = mysqli_query($koneksi,$s);
while ($d= mysqli_fetch_array($resu)){
?>

<script>

var image = document.getElementById('myImage');
if (image.src.match("<?php echo $d['gmbr4'] ?>"))

image.src = "<?php echo $d['gmbr1'] ?>";

假设在排序字段之前没有嵌入逗号,您可以使用awk
来帮助排序并在之后删除任何无关的信息:
awk -F',' -vi=0 '
/^INSERT/ { i=$4 }
{ printf("%08d%08d\t%s\n", i, NR, $0) }
' < data | sort | sed -e 's/^[^\t]*\t//' > newdata
只是输入一个输入文件&#34;数据&#34;到awk
,它将以XXXXXXXX.NNNNNNNN
形式在数据本身之前插入第4个字段的格式化副本,其中XXXXXXXX
表示第4个字段中值的8位数表示找到最后一个INSERT ...
行,NNNNNNNN
表示格式化为8位数值的记录号(行号)。原始数据和格式化数据由制表符分隔。文件不以INSERT
开头的特殊情况(例如空行,解释文件内容的注释等)被视为最后INSERT
行有第四个值为0的字段。这里是结果输出的剪切样本,其中插入了一些额外的行进行测试:
0000000000000001 # This file contains data.
0000001600000002 INSERT,SLT_TEST_5,1218738496,16,DEBUG3,,DEBUG_LEVEL1
0000001600000003 <v s=""MONTHLY_PEAK_DWNLOAD""/>
0000001600000004 </a><a n=""thresholdScheme"">
0000001600000005 <o t=""PM_UsageMonitorConfigThreshold"">
0000001800000006 INSERT,SLT_TEST_1,1218738496,18,DEBUG3,,DEBUG_LEVEL4
0000001800000007 <v s=""ORANGE""/>
0000000500000008 INSERT,SLT_TEST_3,5555738111,5,DEBUG3,,DEBUG_LEVEL1
0000000700000009 INSERT,SLT_TEST_1,9998738342,7,DEBUG3,,DEBUG_LEVEL2
0000000700000010 I'm a little teapot.
生成的行传递给sort
,它将对它接收的行进行排序。然后,sed
将删除sort
脚本最初创建的信息awk
实用程序输出的行,从而导致基于第四个字段的排序,而不会改变行和的行的顺序#39; t以INSERT
开头,输出到文件&#34; newdata&#34;:
# This file contains data.
INSERT,SLT_TEST_3,5555738111,5,DEBUG3,,DEBUG_LEVEL1
INSERT,SLT_TEST_1,9998738342,7,DEBUG3,,DEBUG_LEVEL2
I'm a little teapot.
INSERT,SLT_TEST_5,1218738496,16,DEBUG3,,DEBUG_LEVEL1
<v s=""MONTHLY_PEAK_DWNLOAD""/>
</a><a n=""thresholdScheme"">

我在这一点上有点油腻,而且我很难理解我的哪一部分没有完全正确但这样的事情似乎对你的测试数据起作用(除了添加一个& #34;空白&#34;记录/进入顶部。
awk -v RS='\n?INSERT' -F , '{
gsub(/\n$/,"");
m[sprintf("%04d",$4)]=substr(RS,3)$0
}
END {
l = asorti(m, mm);
for (i = 1; i <= l; i++) {
print m[mm[i]]
}
}'
虽然这个版本在第一条记录上双重RS
(我现在也看不清楚原因)。
awk -v RS='\nINSERT' -F , '{
gsub(/\n$/,"");
m[sprintf("%04d",$4)]=substr(RS,2)$0
}
END {
l = asorti(m, mm);
for (i = 1; i <= l; i++) {
print m[mm[i]]
}
}'
sprintf
是asorti
正确排序字段(字符串排序)。这需要足够大,以便将每个字段填充到相同的宽度。
