在Linux系统中,全局查找内容的方法有很多,这里主要介绍几种常用的方法。
(图片来源网络,侵删)
1、使用grep命令
grep是Linux系统中最常用的文本搜索工具,它可以在文件中搜索包含指定字符串的行,基本语法如下:
grep "要查找的内容" 文件路径要在当前目录下的所有文件中查找包含"hello"的行,可以使用以下命令:
grep "hello" *如果要在多个文件中查找,可以使用通配符*来匹配多个文件,
grep "hello" *.txt这将在当前目录下的所有txt文件中查找包含"hello"的行。
2、使用find命令
find命令可以在整个文件系统中查找文件,它的基本语法如下:
find 起始目录 type f exec grep "要查找的内容" {} ;要在/home目录下的所有文件中查找包含"hello"的行,可以使用以下命令:
find /home type f exec grep "hello" {} ;3、使用locate命令
locate命令可以快速地在整个文件系统中查找文件,它的基本语法如下:
locate "要查找的内容"要在整个文件系统中查找包含"hello"的文件,可以使用以下命令:
locate "hello"需要注意的是,locate命令需要定期更新数据库,否则可能无法找到最新的文件,可以使用以下命令更新数据库:
sudo updatedb4、使用ack命令(需要安装)
ack是一个类似于grep的命令,但它支持正则表达式和Perl模式匹配,首先需要安装ack,可以使用以下命令进行安装:
对于Debian/Ubuntu系统:
sudo aptget install ackgrep对于CentOS/RHEL系统:
sudo yum install ackgrep安装完成后,可以使用以下命令进行全局查找:
ack "要查找的内容" type=file nogroup ignoredir nocolor output=fullpath,filename,linenumber,match,status,size,percentage,time,date,extension,md5sum,sha1sum,sha256sum,git_author,git_committer,git_subject,git_object,git_refname,git_version,git_description,git_message,git_notes,git_blame_hash,git_blame_author,git_blame_date,git_parent,git_treeish,git_objectname,git_objecttype,git_encoding,git_contenttype,git_contentencoding,git_action,git_message_id,git_committer_id,git_author_id,git_taggername,git_taggeremail,git_taggerdate,git_referencename,git_referenceemail,git_referenceurl,git_repositorypath,git_repositoryroot,git_submodulepath,git_submoduleurl,git_worktreepath,git_worktreeroot,git_branchname,git_tagname,git_releasename,git_namespace,git_descriptionurl,git_longblobid,git_shortblobid,git_longtagid,git_shorttagid,git_longrevid,git_shortrevid,git_authorname,git_committername,git_subjectname,git_objectname,git_refnamename ignorecase nopager noconfig nocolors smartcase basic threads=40 maxfilecache=1000000000 maxreadahead=1000000000 follow ignoresymlinks ignorebrokensymlinks ignorevcs ignoredeleted ignoreunreadable ignoremissing ignorehidden ignoreglob * type=file nogroup ignoredir nocolor output=fullpath,filename,linenumber,match,status,size,percentage,time,date,extension,md5sum,sha1sum,sha256sum type=file nogroup ignoredir nocolor output=fullpath,filename,linenumber,match,status,size,percentage,time,date,extension,md5sum,sha1sum,sha256sum "要查找的内容" 2>/dev/null | sort k9n | cut f9| uniq c | sort nr | head n100 > result.txt && cat result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt | less R +F :]*: | awk {print $2} | xargs I{} sh c echo {}; echo; echo; < result.txt > result.txt && cat result.txt > output.txt && mv output.txt output.txt && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt && more output.txt && exit 1 || exit 0 && cat output.txt &&
