Question

我有2个文件： FILE1.TXT

Monday XXXX
Tuesday XXXX
XXXX Wednesday
Thursday XXXX

XXXX位于file1.txt的每一行，我想用file2.txt中的每一行替换它们：

home
school
cinema

所以输出文件是：

Monday home
Tuesday home
home Wednesday
Thursday home
Monday school
Tuesday school
school Wednesday
Thursday school
Monday cinema
Tuesday cinema
cinema Wednesday
Thursday cinema

我得到了file2.txt有很多行，所以我不能手工完成。所以，我需要一个解决方案。谢谢你的时间。

Answer 1

简单如下：

while read i 
do
    sed s/XXXX/$i/ file1.txt
done < file2.txt > output

您在寻找什么？

Answer 2

这可能适合你（GNU sed）：

sed 's|.*|sed s/XXXX/&/g file1|e' file2

这使用GNU特定的e标志在sed命令中运行sed命令。

或者您可以将生成的sed命令传递给shell：

sed 's|.*|sed s/XXXX/&/g file1|' file2 | sh

Answer 3

另一个单独的awk命令：

awk 'BEGIN { while ((getline line < ARGV[1]) > 0) a[i++] = line; ARGV[1] = ""; } { for (i = 1; i in a; ++i) { t = a[i]; gsub(/XXXX/, $0, t); print t }; }' file1 file2

Answer 4

$ awk 'NR==FNR{r=r $0 ORS;next} {t=r; gsub(/XXXX/,$0,t); printf "%s",t}' file1 file2
Monday home
Tuesday home
home Wednesday
Thursday home
Monday school
Tuesday school
school Wednesday
Thursday school
Monday cinema
Tuesday cinema
cinema Wednesday
Thursday cinema
