这是我的档案: myfile.txt:
John Jony Old Boy
Maria Beautiful Girl
Dede YoYo Animal
with:sed 's/ \+ /\ - /g' myfile.txt > ttt.txt
我有这个输出:
John Jony - Old Boy -
Maria - Beautiful Girl -
Dede YoYo - Animal -
但我不想替换第二个“标签”空间。 我只是把第一组和第二组用“空间减去空格(” - “)之间。 谢谢你!
答案 0 :(得分:1)
如果您有更多艺术家喜欢
John Jony Another Name Old Boy
并希望输出:
John Jony & Another Name - Old Boy
然后它有点复杂,但并非awk
:
输入文件:
John Jony Another Name Old Boy
First artist Second artist Third artist Song
Maria Beautiful Girl
Dede YoYo Animal
命令:
awk -F ' +' '
NF==3 {
sub(" +"," - ");
print
}
NF>3 {
for (i=1;i<=NF-3;i++) {
printf("%s",$i);
printf(" & ");
}
printf("%s - %s\n",$(i++),$i);
}' myfile.txt > ttt.txt
<强>输出:强>
John Jony & Another Name - Old Boy
First artist & Second artist & Third artist - Song
Maria - Beautiful Girl
Dede YoYo - Animal
