Question

我有一个庞大的文件，想要以列格式将一组数字复制到另一个文本文件，以便我可以绘制数据。

文字

CC for particle      1 is  0.05378168  phase residual is  78.77

values of PSI,THETA,PHI at FMATCH extraction   88.780   62.638  352.976
Time before particle       2 was  19:31:43

CC for particle      2 is  0.05370924  phase residual is  79.34

values of PSI,THETA,PHI at FMATCH extraction   88.399  123.675  354.108

CC for particle      3 is  0.04939323  phase residual is  78.30

values of PSI,THETA,PHI at FMATCH extraction   87.646   98.585  353.899

CC for particle      4 is  0.05664483  phase residual is  79.33

values of PSI,THETA,PHI at FMATCH extraction   87.755  116.152  350.454

CC for particle      5 is  0.06687291  phase residual is  78.83

我想在粗体中提取行尾的相位残差值。我怎样才能做到这一点？

Answer 1

根据您的示例，我假设您在所需的数字之前总是is：

sed -n 's/.*is *\([0-9]*\.[0-9]*\)$/\1/p' input

这应该得到你想要的粗体数字，但如果你想要，你可以更严格：

sed -n 's/.*phase residual is *\([0-9]*\.[0-9]*\)$/\1/p' input

从大文本复制值（数字）
