我有一个文件，其中的字段用冒号分隔（这些都是虚假的数字/名称，因此无需担心机密性）。我想要完成的是让最后一列看起来更像一个货币价值，即前面有千位分隔符和一个美元符号。

有没有办法用sed做到这一点？如果我可以单独列出最后一列并忽略之前的内容，我觉得我可以轻松地做一些像
这样的事情sed 's/^/$/'
将$符号添加到开头
我的预期输出是：
Arthur Putie:923-835-8745:23 Wimp Lane, Kensington, DL 38758:8/31/69:$126,000
Barbara Kertz:385-573-8326:832 Ponce Drive, Gary, IN 83756:12/1/46:$268,500
Betty Boop:245-836-8357:635 Cutesy Lane, Hollywood, CA 91464:6/23/23:$14,500
... etc
答案 0 :(得分：1)
为了清晰，简单，健壮和良好的软件的所有其他理想的质量，只需使用awk：
$ awk 'BEGIN{FS=OFS=":"} {$NF=sprintf("$%\047d",$NF)} 1' file
Arthur Putie:923-835-8745:23 Wimp Lane, Kensington, DL 38758:8/31/69:$126,000
Barbara Kertz:385-573-8326:832 Ponce Drive, Gary, IN 83756:12/1/46:$268,500
Betty Boop:245-836-8357:635 Cutesy Lane, Hollywood, CA 91464:6/23/23:$14,500
当最后一个字段还有1个数字时，请尝试当前接受的sed和此awk解决方案：
$ cat file
Arthur Putie:923-835-8745:23 Wimp Lane, Kensington, DL 38758:8/31/69:1260000
$ awk 'BEGIN{FS=OFS=":"} {$NF=sprintf("$%\047d",$NF)} 1' file
Arthur Putie:923-835-8745:23 Wimp Lane, Kensington, DL 38758:8/31/69:$1,260,000
$ sed 's/.\{3\}$/,&/;s/[^:]*$/\$&/' file
Arthur Putie:923-835-8745:23 Wimp Lane, Kensington, DL 38758:8/31/69:$1260,000

好像你想要这样的东西。
