Select csv 命令输出中列后的值
Select value after a column in a csv command output
我试图只从我的 gps-programm-output 中读出坐标。
为了得到下面的结果，我使用了下面的命令
minicom -b 9600 -o -D /dev/ttyAMA0 -C /home/logreader/logs/log.txt
我想我要找的是 grep 命令，我只是不知道如何在我的文本文件上使用它。以下是 bash 控制台的输出。我只想要 $GNGLL

如果你想和正则表达式一起使用，你可以使用 grep。
这对你有用：
minicom -b 9600 -o -D /dev/ttyAMA0 -C /home/logreader/logs/log.txt | grep -oP '.*(?:$GNGLL,)\K([^\n\r]*)'
