从Linux终端输出中提取指定数据

从 Linux 终端 ( teqc +qc filename) 中的上一个命令，我直接在终端中收到以下输出：

QC of RINEX  file(s) : whcr0010.18o

从这里，我希望提取以下信息：文件名 ( whcr0010.180) 和观察间隔 ( 15.00)。另外，如果我可以将此信息附加到文本文件中，那就太好了。

答案1

以下awk命令应该执行您需要的操作：

teqc +qc filename | awk -F: '$1 ~ "QC of RINEX  file" || $1 ~ "Observation interval" {print $2}' >>output.txt
