我的专栏数据如下:
A B C D E
1 2 3 4 5
我愿照此办理
怎样才能做到这一点? 我是否应标出两条线,然后用阵列加以打印?
我怎么做。

Awk是好的。
awk NR==1{for(i=0;i<NF;i++){row[i]=$i}} NR==2{for(i=0;i<NF;i++){printf "%s:%s",row[i],$i}} oldfile > newfile
略为可读写本:
#!/usr/bin/awk -f
NR == 1 {
for(i = 0; i < NF; i++) {
first_row[i] = $i
}
}
NR == 2 {
for(i = 0; i < NF; i++) {
printf "%s:%s", first_row[i], $i
}
print ""
}
如果你希望纵向扩大,那么你必须说明如何。
具有任何内容的两个线:
(read LINE;
LINE_ONE=($LINE);
read LINE;
LINE_TWO=($LINE);
for i in `seq 0 $((${#LINE_ONE[@]} - 1))`;
do
echo ${LINE_ONE[$i]}:${LINE_TWO[$i]};
done)
做的是,一线搭桥就把它放在一片路上。
这或许有助于你:
echo -e "A B C D E FFF GGG
1 2 3 4 5 666 7" |
sed s/ |$/:/g;N;:a;s/([^:]*:)([^
]*)
([^: ]+ *)/213
/;ta;s/
//
A:1 B:2 C:3 D:4 E:5 FFF:666 GGG:7
Perl 1-liner:
perl -lane if($.%2){@k=@F}else{print join" ",map{"$k[$_]:$F[$_]"}0..$#F}
更符合逻辑的版本:
#!/usr/bin/perl
my @keys;
while (<>) {
chomp;
if ($. % 2) { # odd lines are keys
@keys = split , $_;
} else { # even lines are values
my @values = split , $_;
print join , map { "$keys[$_]:$values[$_]" } 0..$#values;
}
}
