当前目录下搜索：find . -name "*.*" | xargs grep "password=*" --color=always
备注：这个命令会输出当前目录下不存在匹配字符串的的子目录
完美的当前目录下搜索字符串命令：grep "password=*" -R -n --color=always
全量目录搜索：find / -name "*.*" | xargs grep -i "password=*" |grep -v "password=*" --color=always
逐层搜索文件夹以及子文件关键字：
find / -type f | egrep "\.log\$"| xargs grep -n -E -H "*assword=*" | egrep ":[ ]*[_a-zA-Z]" | sed "s:/\*.*\*/::g;s://.*::g" | egrep "*assword=*" --color=always
不同文件类型并列搜索：find / -type f | egrep "\.log\$|\.sh\$|\.xml\$" | xargs grep -i "password" --color=always
精确查找关键字：
find / -type f -name "*.log" | xargs grep -i "password" --color=always
find / -type f -name "*.log" | xargs grep -i "password" --color=auto
find / -type f | egrep "\.log\$" | xargs grep -i "password" --color=always
匹配多条件查找：可以采用or条件操作
find /var/log \( -name "rsync_yum_2016*" -o -name "rsync_yum_2017*" \) 备注：注意\(后面的空格，还有\)前面的空格
或者find /var/log -name "rsync_yum_2016*" -o -name "rsync_yum_2017*"
模糊匹配查找关键字：
1)模糊匹配文件类型 与 模糊匹配 关键字
1、【搜索慢】按字节块字符来匹配搜索
find / -type f -name "*.*" | xargs grep -R -i -E '*@storage*|*assword*' --color=always
2.【搜索快】高精度 精确性搜索
find / -type f | egrep "\.log\$" | xargs grep -R -i -E '*@storage*|*assword*' --color=always
find / -type f | egrep "\.log\$|\.sh\$" | xargs grep -R -i -E "*@storage*|*assword*" --color=always
2)指定文件类型 与 模糊匹配 关键字
find / -type f -name "*.log" | xargs grep -n -E -H "*@storage*" --color=always
find / -type f | egrep "\.log\$" | xargs grep -R -i -E '*@storage*' --color=always
find / -type f | egrep "*.log" |xargs grep -n -E -H '*storage*' --color=always
find / -type f | egrep "\.log\$"| xargs grep -n -E -H "*@storage*" | egrep ":[ ]*[_a-zA-Z]" | sed "s:/\*.*\*/::g;s://.*::g" | egrep "*@storage*|*assword*" --color=always
目录下搜索：grep -niR 'Admin@storage' / --color=always
cat *.* | grep -n -E -H '*@storage*|*assword*' --color=always
cat *.* | grep -R -i -E '*@storage|*assword' --color=always
在多/多个不同文件类型中查找
1)指定多个个文件类型使用grep，egrep并列过滤
find / -type f | egrep "\.sql\$|\.log\$|\.cfg\$|\.cpp\$|\.h\$|\.hpp\$|\.htm\$|\.html\$|\.inc\$|\.Java\$|\.js\$|\.jsp\$|\.pl\$|\.properties\$|\.sh\$|\.xml\$"| xargs grep -n -E -H "pass|password" | egrep ":[ ]*[_a-zA-Z]" | sed "s:/\*.*\*/::g;s://.*::g" | egrep "pass|password" > check_Security.log
2)指定单个文件类型 使用grep，egrep并列过滤
find / -type f | egrep egrep "\.log\$" | xargs grep -n -E -H "*storage" | egrep ":[ ]*[_a-zA-Z]" | sed "s:/\*.*\*/::g;s://.*::g" | egrep "*storage" --color=always
