If tree is not installed on your Centos system (I typically recommend server setups to use minimal install disk anyhow) you should type the following at your command line:

# yum install tree -y

If this doesn't install it's because you don't have the proper repository. I would use the Dag Wieers repository:

http://dag.wieers.com/rpm/FAQ.php#B

After that you can do your install:

# yum install tree -y

Now you're ready to roll. Always read the man page: http://linux.die.net/man/1/tree

So quite simply the following will return a tree:

# tree

Alternatively you can output this to a text file. There's a ton of options too.. Again, read your man page if you're looking for something other than default output.

# tree > recursive_directory_list.txt

(^^ in a text file for later review ^^)

你可以制作自己的原始“树”（为了好玩:)）

#!/bin/bash
# only if you have bash 4 in your CentOS system
shopt -s globstar
for file in **/*
do
    slash=${file//[^\/]}
    case "${#slash}" in
        0) echo "|-- ${file}";;
        1) echo "|   |--  ${file}";;
        2) echo "|   |   |--  ${file}";;
    esac
done

You can make your own primitive "tree" ( for fun :) )

#!/bin/bash
# only if you have bash 4 in your CentOS system
shopt -s globstar
for file in **/*
do
    slash=${file//[^\/]}
    case "${#slash}" in
        0) echo "|-- ${file}";;
        1) echo "|   |--  ${file}";;
        2) echo "|   |   |--  ${file}";;
    esac
done

由于 CentOS 中默认情况下未安装 tree ...

[user@CentOS test]$ tree
-bash: tree: command not found
[user@CentOS test]$

您还可以使用以下 ls 命令生成与 tree

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'

示例几乎相似的输出：

[user@CentOS test]$ ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'
   .
   |-directory1
   |-directory2
   |-directory3
[user@CentOS directory]$

Since tree is not installed by default in CentOS ...

[user@CentOS test]$ tree
-bash: tree: command not found
[user@CentOS test]$

You can also use the following ls command to produce almost similar output with tree

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'

Example:

[user@CentOS test]$ ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'
   .
   |-directory1
   |-directory2
   |-directory3
[user@CentOS directory]$

你好，陌生人 2024-11-09 16:08:35

正如您在此处看到的那样。 CentOs 中默认未安装 tree，因此您需要查找 RPM 并手动安装它

您在基础存储库中有树。

显示它 (yum list package-name):

# yum list tree
Available Packages
tree.i386               1.5.0-4               base

安装它:

yum install tree

(在 CentOS 5 和 6 上验证)

You have tree in the base repo.

Show it (yum list package-name):

# yum list tree
Available Packages
tree.i386               1.5.0-4               base

Install it:

yum install tree

(verified on CentOS 5 and 6)

我需要在不允许我进行 yum 安装的远程计算机上工作。所以我修改了 bash-o-logger 的答案以获得更灵活的答案。

它需要一个（可选）参数，该参数是您要显示的子目录的最大级别。将其添加到您的 $PATH 中，即可享受无需安装的 tree 命令。

我不是 shell 专家（为了这个非常短的脚本，我不得不用 Google 搜索很多次）。所以如果我做错了什么，请告诉我。太感谢了！

#!/bin/bash
# only if you have bash 4 in your CentOS system

shopt -s globstar # enable double star

max_level=${1:-10}

for file in **
do
    # Get just the folder or filename
    IFS='/'
    read -ra ADDR <<< "$file"
    last_field=${ADDR[-1]}
    IFS=' '

    # Get the number of slashes
    slash=${file//[^\/]}
    
    # print folder or file with correct number of leadings
    if [ ${#slash} -lt $max_level ]
    then
        spaces="   "
        leading=""
        if [ "${#slash}" -gt 0 ]
        then
            leading=`eval $(echo printf '"|${spaces}%0.s"' {1..${#slash}})`
        fi
        echo "${leading}|-- $last_field"
    fi
done

I need to work on a remote computer that won't allow me to yum install. So I modified bash-o-logist's answer to get a more flexible one.

It takes an (optional) argument that is the maximum level of subdirectories you want to show. Add it to your $PATH, and enjoy a tree command that doesn't need installation.

I am not an expert in shell (I had to Google a ton of times just for this very short script). So if I did anything wrong, please let me know. Thank you so much!

#!/bin/bash
# only if you have bash 4 in your CentOS system

shopt -s globstar # enable double star

max_level=${1:-10}

for file in **
do
    # Get just the folder or filename
    IFS='/'
    read -ra ADDR <<< "$file"
    last_field=${ADDR[-1]}
    IFS=' '

    # Get the number of slashes
    slash=${file//[^\/]}
    
    # print folder or file with correct number of leadings
    if [ ${#slash} -lt $max_level ]
    then
        spaces="   "
        leading=""
        if [ "${#slash}" -gt 0 ]
        then
            leading=`eval $(echo printf '"|${spaces}%0.s"' {1..${#slash}})`
        fi
        echo "${leading}|-- $last_field"
    fi
done
