简介浏览他人技术博客的时候,会看到用文本列出漂亮的文件夹目录,实际大部分都是使用了Linux下的Tree命令。以下简单介绍下Tree命令的格式和例子。 安装一般Linux系统是不自带Tree命令工具的,可以通过以下命令获取和安装: sudo apt-get install tree 格式通过上述命令获取后,可以通过一下命令显示使用方法: tree --help 显示如下: usage: tree [-acdfghilnpqrstuvxACDFJQNSUX] [-H baseHREF] [-T title ] [-L level [-R]] [-P pattern] [-I pattern] [-o filename] [--version] [--help] [--inodes] [--device] [--noreport] [--nolinks] [--dirsfirst] [--charset charset] [--filelimit[=]#] [--si] [--timefmt[=]<f>] [--sort[=]<name>] [--matchdirs] [--ignore-case] [--] [<directory list>] ------- Listing options ------- -a All files are listed. -d List directories only. -l Follow symbolic links like directories. -f Print the full path prefix for each file. -x Stay on current filesystem only. -L level Descend only level directories deep. -R Rerun tree when max dir level reached. -P pattern List only those files that match the pattern given. -I pattern Do not list files that match the given pattern. --ignore-case Ignore case when pattern matching. --matchdirs Include directory names in -P pattern matching. --noreport Turn off file/directory count at end of tree listing. --charset X Use charset X for terminal/HTML and indentation line output. --filelimit # Do not descend dirs with more than # files in them. --timefmt <f> Print and format time according to the format <f>. -o filename Output to file instead of stdout. -------- File options --------- -q Print non-printable characters as '?'. -N Print non-printable characters as is. -Q Quote filenames with double quotes. -p Print the protections for each file. -u Displays file owner or UID number. -g Displays file group owner or GID number. -s Print the size in bytes of each file. -h Print the size in a more human readable way. --si Like -h,but use in SI units (powers of 1000). -D Print the date of last modification or (-c) status change. -F Appends '/','=','*','@','|' or '>' as per ls -F. --inodes Print inode number of each file. --device Print device ID number to which each file belongs. ------- Sorting options ------- -v Sort files alphanumerically by version. -t Sort files by last modification time. -c Sort files by last status change time. -U Leave files unsorted. -r Reverse the order of the sort. --dirsfirst List directories before files (-U disables). --sort X Select sort: name,version,size,mtime,ctime. ------- Graphics options ------ -i Don't print indentation lines. -A Print ANSI lines graphic indentation lines. -S Print with CP437 (console) graphics indentation lines. -n Turn colorization off always (-C overrides). -C Turn colorization on always. ------- XML/HTML/JSON options ------- -X Prints out an XML representation of the tree. -J Prints out an JSON representation of the tree. -H baseHREF Prints out HTML format with baseHREF as top directory. -T string Replace the default HTML title and H1 header with string. --nolinks Turn off hyperlinks in HTML output. ---- Miscellaneous options ---- --version Print version and exit. --help Print usage and this help message and exit. -- Options processing terminator. 可以看到最新的Tree命令工具在老版本基础上已经做了很多扩展,分别有Listing、File 、Graphics、 XML/HTML/JSON 、 举例虽然现在功能越来越强大,但是对于大部分人来说常用的并不多,以下举几个常用的例子: 显示全部层级的目录和文件tree -a . ├── 1.txt ├── demo1 │ ├── CMakeCache.txt │ ├── CMakeFiles │ │ ├── 3.5.1 │ │ │ ├── CMakeCCompiler.cmake │ │ │ ├── CMakeCXXCompiler.cmake │ │ │ ├── CMakeDetermineCompilerABI_C.bin │ │ │ ├── CMakeDetermineCompilerABI_CXX.bin │ │ │ ├── CMakeSystem.cmake │ │ │ ├── CompilerIdC │ │ │ │ ├── a.out │ │ │ │ └── CMakeCCompilerId.c │ │ │ └── CompilerIdCXX │ │ │ ├── a.out │ │ │ └── CMakeCXXCompilerId.cpp │ │ ├── cmake.check_cache │ │ ├── CMakeDirectoryInformation.cmake │ │ ├── CMakeOutput.log │ │ ├── CMakeTmp │ │ ├── Demo.dir │ │ │ ├── build.make │ │ │ ├── cmake_clean.cmake │ │ │ ├── CXX.includecache │ │ │ ├── DependInfo.cmake │ │ │ ├── depend.internal │ │ │ ├── depend.make │ │ │ ├── flags.make │ │ │ ├── link.txt │ │ │ ├── main.cc.o │ │ │ └── progress.make │ │ ├── feature_tests.bin │ │ ├── feature_tests.c │ │ ├── feature_tests.cxx │ │ ├── Makefile2 │ │ ├── Makefile.cmake │ │ ├── progress.marks │ │ └── TargetDirectories.txt │ ├── cmake_install.cmake │ ├── CMakeLists.txt │ ├── Demo │ ├── main.cc │ └── Makefile └── demo2 显示指定层级的目录和文件tree -L 2 // -L 指定目录深度 . ├── 1.txt ├── demo1 │ ├── CMakeCache.txt │ ├── CMakeFiles │ ├── cmake_install.cmake │ ├── CMakeLists.txt │ ├── Demo │ ├── main.cc │ └── Makefile └── demo2 显示目录/文件地址tree -L 2 -f . ├── ./1.txt ├── ./demo1 │ ├── ./demo1/CMakeCache.txt │ ├── ./demo1/CMakeFiles │ ├── ./demo1/cmake_install.cmake │ ├── ./demo1/CMakeLists.txt │ ├── ./demo1/Demo │ ├── ./demo1/main.cc │ └── ./demo1/Makefile └── ./demo2 仅显示目录不显示文件tree -L3 -d . ├── demo1 │ └── CMakeFiles │ ├── 3.5.1 │ ├── CMakeTmp │ └── Demo.dir └── demo2 区分目录和文件tree -L 2 -F . ├── 1.txt ├── demo1/ │ ├── CMakeCache.txt │ ├── CMakeFiles/ │ ├── cmake_install.cmake │ ├── CMakeLists.txt │ ├── Demo* │ ├── main.cc │ └── Makefile └── demo2/ 不显示目录树中的层级线tree -L 2 -i . 1.txt demo1 CMakeCache.txt CMakeFiles cmake_install.cmake CMakeLists.txt Demo main.cc Makefile demo2 显示XML格式tree -L 2 -X <?xml version="1.0" encoding="UTF-8"?> <tree> <directory name="."> <file name="1.txt"></file> <directory name="demo1"> <file name="CMakeCache.txt"></file> <directory name="CMakeFiles"> </directory> <file name="cmake_install.cmake"></file> <file name="CMakeLists.txt"></file> <file name="Demo"></file> <file name="main.cc"></file> <file name="Makefile"></file> </directory> <directory name="demo2"> </directory> </directory> <report> <directories>3</directories> <files>7</files> </report> </tree> 保存内容tree -L 2 >> 1.txt 总结作为常用命令,Tree命令在平时使用中可以帮助我们快速了解当前的目录/文件结构,也可以辅助写处更漂亮的博客。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
