•  查看库属于哪个编译器：

  • # readelf -p .comment libascendcl.so 
    String dump of section '.comment':
      [     0]  GCC: (HC&C V1R3C00SPC200B042_20221123) 7.3.0
    
    # aarch64-mix210-linux-gcc --version

• 查看公网ip:  curl ifconfig.me
• 驱动里面查找打印字符串：strings ot_mipi_rx.ko | grep "fxw" 

 

• 查找关键字并替换： find . -type f -exec sed -i 's/aaa/bbb/g' {} +
  • find .  -name '*.mk' -type f -exec sed -i 's/aaa/bbb/g' {} +
  • find .  \( -name 'Makefile' -o -name '*.mk' \) -type f -exec sed -i 's/aaa/bbb/g' {} +
• 在库里面查找函数并输出库名：find out/lib/ -name *.so -exec nm -DA {} + | grep AAA   // 静态库： -gA
• 查找包含 1.8.3 但不包含 ?v=1.8.3 的： grep -inr '1.8.3' . | grep -v '?v=1.8.3'
