Question

我需要从.map文件中收集目标文件的所有名称，列出它们，然后计算它们在不同内存区域中占用的空间。地图文件很大（<2500行）并且手动操作需要花费很多时间。我试过了

           grep -r '.o' *.map

但它给了我很多结果，其中包含了＆＃39; o。这是来自地图文件的示例

我只需要列出此地图文件中的目标文件列表。

Answer 1

我不知道你是什么意思list of object files，但试试这行：

 grep -r -Po '[^(]*[.]o(?=[)])' *.map

结果是：

start.o
contiki-main.o
start.o
contiki-main.o
mio_dma_drv.o
dma_drv.o
memory_map.o
mio_dma_drv.o
socVer.o
c_fuction.o
Rip_api.o
irq_handler.o
mio_dma_drv.o
