考虑到您的实际 Input_file 与显示的示例相同,请您尝试一次。
awk -v RS="" '
{
gsub(/\n|, /,",")
}
1' Input_file |
awk '
{
while(match($0,/\([^\)]*/)){
value=substr($0,RSTART+1,RLENGTH-2)
$0=substr($0,RSTART+RLENGTH)
num=split(value,array,",")
for(i=1;i<=num;i++){
val[i]=val[i]?val[i] OFS array[i]:array[i]
}
}
for(j=1;j<=num;j++){
print val[j]
}
delete val
delete array
value=""
}' OFS="; "
或(以上脚本考虑 (...) 内的数字将保持不变,现在添加脚本,该脚本将处理 (....) 内不相等的偶数字段数。
awk -v RS="" '
{
gsub(/\n/,",")
gsub(/, /,",")
}
1' Input_file |
awk '
{
while(match($0,/\([^\)]*/)){
value=substr($0,RSTART+1,RLENGTH-2)
$0=substr($0,RSTART+RLENGTH)
num=split(value,array,",")
for(i=1;i<=num;i++){
val[i]=val[i]?val[i] OFS array[i]:array[i]
max=num>max?num:max
}
}
for(j=1;j<=max;j++){
print val[j]
}
delete val
delete array
}' OFS="; "
输出如下。
1; 11; 111
2; 22; 222
3; 33; 333
