cscope 过滤目录介绍

第一步创建自己的cscope脚本~/.local/bin/cscope.sh，如下：

function my_cscope()
{CODE_PATH=`pwd`echo "$CODE_PATH"echo "start cscope...."if [ ! -f "$CODE_PATH/cscope.files" ];thenecho "cscope.files not exist!"elserm -f $CODE_PATH/cscope.*fiif [ ! -d "$CODE_PATH/rt-thread" ];thenfind . \( -path './arch/arc'            \-o -path './arch/alpha'             \-o -path "./arch/blackfin"          \-o -path "./arch/cris"              \-o -path "./arch/h8300"             \-o -path "./arch/ia64"              \-o -path "./arch/m68k"              \-o -path "./arch/microblaze"        \-o -path "./arch/mn10300"           \-o -path "./arch/openrisc"          \-o -path "./arch/powerpc"           \-o -path "./arch/score"             \-o -path "./arch/sparc"             \-o -path "./arch/um"                \-o -path "./arch/x86"               \-o -path "./arch/c6x"               \-o -path "./arch/m32r"              \-o -path "./arch/microblaze"        \-o -path "./arch/nios2"             \-o -path "./arch/powerpc"           \-o -path "./arch/sh"                \-o -path "./arch/um"                \-o -path "./arch/xtensa"            \-o -path "./arch/cris"              \-o -path "./arch/hexagon"           \-o -path "./arch/mips"              \-o -path "./arch/openrisc"          \-o -path "./arch/s390"              \-o -path "./arch/sparc"             \-o -path "./arch/unicore32"         \-o -path "./arch/parisc"            \-o -path "./arch/tile"              \-o -path "./arch/tile"              \-o -path './arch/c6x' \)            \-prune -o -name "*.[chxsS]" -print > cscope.fileselsefind . \( -path "./rtos/rt-thread/rt-thread/bsp/mb9*" \-o -path "./rtos/rt-thread/rt-thread/bsp/at91*" \-o -path "./rtos/rt-thread/rt-thread/bsp/ess*" \-o -path "./rtos/rt-thread/rt-thread/bsp/gd3*" \-o -path "./rtos/rt-thread/rt-thread/bsp/lpc*" \-o -path "./rtos/rt-thread/rt-thread/bsp/ls*" \-o -path "./rtos/rt-thread/rt-thread/bsp/mi*" \-o -path "./rtos/rt-thread/rt-thread/bsp/imx*" \-o -path "./rtos/rt-thread/rt-thread/bsp/rasp*" \-o -path "./rtos/rt-thread/packages/packages/iot/*" \-o -path "./rtos/rt-thread/rt-thread/bsp/stm32/stm32f*" \-o -path "./bootrom"        \-o -path "./u-boot"         \-o -path "./tools" \)       \-prune -name "*.cc" -o -name "*.[chxsS]" \-print > cscope.filesfiecho "cscope -Rbkq -i cscope.files"cscope -Rbkq -i $PWD/cscope.files > cscope.log 2>&1echo "cscope finished"
}my_cscope;

我的这个脚本首先去区分当前执行cscope命令的目录是rt-thread目录还是linux 目录，因为不同的代码要过滤过目录不一样。
此外，还会通过 重定向 将cscope在解析文件cscope.files过程中输出的log重定向到 cscope.log 方便问题问题。关于 find 命令的使用见 find 命令高效使用文章

第二步在 ~/.bashrc 中添加 mycscope 命令，添加完后，别忘记执行 source ~/.bashrc。

alias mycscope='source ~/.local/bin/cscope.sh'

第三部测试效果：

 (*^~^*) ~/workbase/cix_linux/linux> mycscope
/home/sam/workbase/linux
start cscope....
cscope -Rbkq -i cscope.files
cscope finished
(*^~^*) ~/workbase/cix_linux/linux> ls
