使用awk连接两行
[英]concatenation of two lines using awk
问题描述
I have a file with each row having 74 columns. 
我有一个文件，每一行有74列。 I have been trying to combine these lines if the first and second column matches. 如果第一列和第二列匹配，我一直在尝试合并这些行。 The file looks like below. 该文件如下所示。
CHECK_IN|2000000000|MS|XXXX|XXXX|N|34|N|N|N|N|N|Y|N|N|N|N|N|123456|aaaaaa|122333|||||||||||AAAAAA|BBBBBBB|CCCCCCC|||||||||||||||||||1000123|aaaa|N|qwerty||REGISTERED|REGISTERED|REGISTERED|UNREGISTERED|19-05-2015|Video|EDM||||||||||xxxxx
CHECK_IN|2000000000|MS|XXXX|XXXX|N|34|N|Y|N|N|N|N|N|N|N|N|N|345676|Abcgdwejj|aaaaaaa||||||||||||||||||||||||NNNNNNN||||||||1000001|cccccc|N|qyuirt||REGISTERED|REGISTERED|REGISTERED|UNREGISTERED|19-05-2015|Video|EDM||||||||||xxxxx
I have used the below script: 我使用了以下脚本：
cat sample_file4.txt | awk -F "|" '{line="";
for(i = 3; i <= NF ;i++)
line = line $i"|";
table[$1"|"$2]=table[$1"|"$2]"|"line;}
END { for (key in table) print key "==>" table[key];}' > output9.txt
The record is not appended to the first line.Except the key values, the same line is being repeated.like below 记录未添加到第一行，除键值外，同一行被重复，如下所示
1.CHECK_IN|2000000000==>|MS|XXXX|XXXX|N|34|N|N|N|N|N|Y|N|N|N|N|N|123456|aaaaaa|122333|||||||||||AAAAAA|BBBBBBB|CCCCCCC|||||||||||||||||||1000123|aaaa|N|qwerty||REGISTERED|REGISTERED|REGISTERED|UNREGISTERED|19-05-2015|Video|EDM||||||||||xxxxx

I would write this: 我会这样写：
awk '
BEGIN {FS = OFS = "|"}
{ key = $1 SUBSEP $2 }
!(key in lines) {lines[key]=$0; next}
{$1=$2=""; line=$0; sub(/^../, "", line); lines[key] = lines[key] FS line}
END {for (key in lines) {print lines[key]}}
' file
