grep 笔记

2023年10月14日 495次阅读来源: PowerManagerService

-a ：将 binary 文件以 text 文件的方式搜寻数据
-c ：计算找到 ‘搜寻字符串’ 的次数
-i ：忽略大小写的不同，所以大小写视为相同
-n ：顺便输出行号
-v ：反向选择，亦即显示出没有 ‘搜寻字符串’ 内容的那一行！
–color=auto ：可以将找到的关键词部分加上颜色的显示喔！
-r
-w 全子匹配
-E 使用egrep功能，多字匹配

grep -E? ?’aaaaa|bbbbbb’

grep -E ‘SIGNAL|OFL Hit’

logcat -s MiSysSrv MiMwIptvSrv MiMwTvosSrv

logcat -c;logcat -v time -s ld-linux.so.3 MiSysSrv | grep -v ‘mi_display_GetSourceType|mi_atom_display_GetSourceType’

logcat -c;logcat -v time -s ld-linux.so.3 MiSysSrv | grep -v ‘<<<mi_’

-v time -s ld-linux.so.3 | grep -E ‘u32Brightness|sharpness_t’

grep -E? ?’aaaaa|bbbbbb’

grep -nriE ‘SVCMGR|APMLIB’ ok.txt

logcat -c;logcat | grep -v ‘tvos|RootActivity|TvManager_JNI’

logcat -c;logcat | grep -v ‘tvos’ | grep -v ‘RootActivity’ | grep -v ‘TvManager_JNI’

–color

如果类似于含有”test、auto_load”之类的文件我也不显示，怎么做呢？我之前的做法是：
grep -r “UserService” ./ | grep -v “svn\|prj\|test\|auto_load”
