本文介绍了一种在Linux环境中批量替换指定目录下所有C源文件中特定路径的方法。通过find命令结合grep筛选出所有.c文件，并利用sed进行批量替换，最后验证替换效果并清理不需要的行。

1. 找出所有.c文件

leon$  find ./ -maxdepth 3 -type f | grep "\.c"

./misc/nv_net_udp.c
./nv_comm_system.c
./util/nv_report_event.c
./util/nv_linklist_connect_info.c
./transport/net_udp.c
./transport/net_tcp.c
./transport/net_secure_tcp.c
./session/nv_client_session.c
./session/nv_client_accept.c
./session/nv_app_srv_session.c
./session/nv_tran_srv_session.c
./session/nv_session.c
./connect/nv_tran_srv_connect.c
./connect/nv_connect.c
./connect/nv_app_srv_connect.c
./connect/nv_picture_srv_connect.c

2. 需要被批量替换的内容

../../ 替换为 ./

3.查找需要被替换的内容

leon$ for i in `find ./ -maxdepth 3 -type f | grep "\.c"`; do grep "\.\./\.\./" $i ; done

4. 替换

for i in `find ./ -maxdepth 3 -type f | grep "\.c"`; do sed -i 's/\.\.\/\.\.\//\.\//g' $i ; done

5. 查看替换后的内容

leon$  for i in `find ./ -maxdepth 3 -type f | grep "\.c"`; do grep "\.\/" $i ; done

6. 删除匹配行

for i in `find ./ -maxdepth 3 -type f | grep "\.c"`; do sed -i '/\.\.\/\.\.\//d' $i ; done

7.拓展

将 含有字符串"/mnt/nfs/zhuqh/goke/nvc-hi3518-kernel/linux-3.4.y" 替换为 "/opt/hi3518/Hi3518E_SDK_V1.0.3.0/osdrv/opensource/kernel/linux-3.4.y
"

for i in `grep "/mnt/nfs/zhuqh/goke/nvc-hi3518-kernel/linux-3.4.y" * -nR |  cut -d ':' -f1`; do sed -i "s#/mnt/nfs/zhuqh/goke/nvc-hi3518-kernel/linux-3.4.y#/opt/hi3518/Hi3518E_SDK_V1.0.3.0/osdrv/opensource/kernel/linux-3.4.y#g"  $i ; done

注意：这里使用 # 来代替 / 进行sed语法转义。
