10: grep命令结合find命令搜索
[oracle@DB-Server admin]$ find . -name '*.sql' -exec grep -i 'v\$temp_space_header' {} \; -print create or replace view v_$temp_space_header as select * from v$temp_space_header; create or replace public synonym v$temp_space_header for v_$temp_space_header; create or replace view gv_$temp_space_header as select * from gv$temp_space_header; create or replace public synonym gv$temp_space_header FROM gv$temp_space_header ./catspace.sql drop public synonym v$temp_space_header; drop public synonym gv$temp_space_header; ./catspacd.sql [oracle@DB-Server admin]$
11: egrep -w -R 'word1|word2' ~/klbtmp
12: vi命令其实也能搜索文件里面的内容，只不过没有grep命令功能那么方便、强大。
