嗨，我正在尝试从 .dat 文件中 grep 某些行并将它们放入新文件 test.dat（或 .txt）中。我想 grep 日期/时间 (2012Sep212357) 和以 (FD12P 开头并以 PARS 结尾的行。请记住，2012Sep 之后的日期/时间正在改变。我试过了

grep '^2012Sep.*AA$' |'^FD12P.*PARS$' file.dat > test.dat

但它不起作用，输出应该是：

您在这里有两个不同的操作。首先是行的选择，将自己限制为仅以字符串开头2012Sep并包含字符串FD12P和, PARS（按此顺序）的行。

第二个是过滤这些行中的每一行，以仅保留日期和和之间的文本FDP12（PARS不包括PARS本身）。

第一个操作可以用grep管道中的 a 完成，第二个操作可以用 a 完成sed：

grep '^2012Sep.*, FD12P.*, PARS' infile.dat
    | sed -e 's/ .*, FD12P/, FD12P/'
          -e 's/, PARS.*$//'
    >outfile.dat

这取决于您应该检查的几件事。

  • 日期后紧跟一个空格；
  • 只有一个FDP12和PARS在行中；
  • FD12PandPARS总是以（", "逗号、空格）开头。

如果其中任何一个结果不正确，您可能需要调整 和 的grep参数sed。如果违反了第二条规则，这尤其值得关注，因为您必须更详细地指定您希望它的行为方式。

以下记录显示了这一点：

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

您可以通过提供多个来分隔正则表达式-e：

grep -e '^2012Sep' -e '^FD12P.*PARS$' file.dat

另外，从您在上一个答案中的最后一条评论中，我了解到您不仅想找到匹配的行，还想提取匹配的行。

使用 gnu grep，您可以使用以下-o标志：

grep -oe '^2012Sep' -e '^FD12P.*PARS$' file.dat

编辑：

假设您要查找以 2012Sep 开头并包含 FD12P 和 PARS 的所有行，并且只输出特定部分。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 默认情况下不要回显行
  • p当行匹配时，该标志告诉 sed 输出行
  • 括号创建要保留的数据组
  • \1 和 \2 引用组
  • 我们匹配整行（我们想要的数据周围的.*），这意味着只有我们的替换将保留
