HI我试图从.dat文件中获取某些行并将它们放入一个新文件test.dat（或.txt）中。我想grep日期/时间（2012Sep212357）和以（FD12P开头，以PARS结尾）的行。请记住2012Sep之后的日期/时间正在改变。我试过
grep '^2012Sep.*AA$' |'^FD12P.*PARS$' file.dat > test.dat
但是它不起作用，输出应该是：

答案 0 :(得分：2)
这里有两个截然不同的操作。第一个是行的选择，仅限于那些以2012Sep开头且包含字符串FD12P和, PARS（按此顺序）的行。
第二个是对这些行中的每个行进行过滤，以仅保留FDP12和PARS之间的日期和文字（不包括PARS本身）。
第一个操作可以在管道中使用grep完成，第二个操作可以使用sed完成：
grep '^2012Sep.*, FD12P.*, PARS' infile.dat
| sed -e 's/ .*, FD12P/, FD12P/'
-e 's/, PARS.*$//'
>outfile.dat
这取决于你应该检查的一些事情。
FDP12和PARS; FD12P和PARS始终以", "开头（逗号，空格）。如果其中任何一个结果不正确，您可能需要调整grep和sed的参数。如果违反了第二条规则，则特别值得关注，因为您必须更详细地指定您希望它的行为方式。
以下成绩单显示了这一点：
pax> cat qq.in
2012Sep212357 23:56, AAA_YMDHMS, FD12P_S/N , blah, PARS, more blah
a dummy line which should not match
2012Sep212358 23:57, AAA_YMDHMS, FD12P_S/N , yada, PARS_xyzzy, more yada
pax> grep '^2012Sep.*FD12P.*, PARS' qq.in
...> | sed -e 's/ .*FD12P/, FD12P/' -e 's/, PARS.*$//'
2012Sep212357, FD12P_S/N , blah
2012Sep212358, FD12P_S/N , yada
答案 1 :(得分：1)
您可以通过提供多个-e来分隔您的正则表达式：
grep -e '^2012Sep' -e '^FD12P.*PARS$' file.dat
另外，根据您在上一个回答中的上一条评论，我收集到您不仅要查找匹配的行，还要提取匹配的内容。
使用gnu grep，您可以使用-o标志：
grep -oe '^2012Sep' -e '^FD12P.*PARS$' file.dat
修改
鉴于您要查找以2012Sep开头且包含FD12P和PARS的所有行，并且仅输出特定部分。 sed在这种情况下更有意义：
sed -ne 's#^\(2012Sep[^ ]*\).*\(FD12P.*\)PARS.*#\1,\2#p' file.dat | sed -e 's# *# #g'
-n告诉sed默认不回显p标志告诉sed在行匹配时输出行
