stree
is a CLI tool designed to visualize the directory tree structure of an S3 bucket.
By inputting an S3 bucket/prefix and utilizing various flags to customize your request, you can obtain a colorized or non-colorized directory tree right in your terminal.
Whether it's for verifying the file structure, sharing the structure with your team, or any other purpose, stree
offers an easy and convenient way to explore your S3 buckets.

- Colorized Output: By default,
stree
provides a colorized tree structure, making it easy to differentiate between directories and files at a glance. This feature can be turned off with the-n
or--no-color
flag. - LocalStack Support:
stree
supports local testing with LocalStack, a fully functional local AWS cloud stack, thanks to the--local
and--endpoint-url
flags. - Custom AWS Profile and Region: Specify the AWS profile and region with the
--profile
and--region
flags to override the default settings as needed. - Ease of Installation: Install
stree
via Go, Homebrew, or by downloading the latest compiled binaries from the GitHub releases page. - Depth level Specification: With the new
--L
flag, you can now specify how many levels deep in the directory structure you'd like to visualize. This offers a more focused view, especially for large S3 buckets. - Role Switching Support:
stree
is now enhanced with the ability to switch AWS roles with MFA using the--mfa
flag. This makes it easier to manage and view S3 buckets that require different IAM roles for access. - Environment Variable Support:
stree
now prioritizes environment variables for AWS Profile and Region settings. The tool will use theAWS_PROFILE
environment variable if set, falling back to thedefault
profile otherwise. Similarly, it will use theAWS_REGION
orAWS_DEFAULT_REGION
environment variables for the AWS region, if available. (see AWS CLI Environment Variables for more information)
go install github.com/orangekame3/stree@latest
brew install orangekame3/tap/stree
Download the latest compiled binaries and put it anywhere in your executable path.
Warning Prerequisite You must set up the config and credentials to be used with aws cli in advance
From here on, it is assumed that the config and credentials are set as follows.
~/.aws/config
[my_profile]
region = ap-northeast-1
output = json
~/.aws/credentials
[my_profile]
aws_access_key_id=XXXXXXXXXXXXXXXXXXXXX
aws_secret_access_key=XXXXXXXXXXXXXXXXX
Specify the bucket name and profile, and execute the following command. The profile is specified with --profile (-p)
.
stree my-bucket -p my_profile
You will get the following output.
my-bucket
โโโ test
โโโ dir1
โ โโโ dir1_1
โ โ โโโ dir1_1_1
โ โ โโโ file1.csv
โ โ โโโ file2.csv
โ โโโ dir1_2
โ โโโ file1.csv
โ โโโ file2.csv
โ โโโ file3.csv
โโโ dir2
โ โโโ dir2_1
โ โโโ dir2_1_1
โ โโโ file1.csv
โ โโโ file2.csv
โ โโโ file3.csv
โโโ dir3
โโโ file1.csv
โโโ file2.csv
9 directories, 10 files
stree my-bucket/test/dir2 -p my_profile
The result of executing this command is as follows.
my-bucket
โโโ test
โโโ dir2
โโโ dir2_1
โโโ dir2_1_1
โโโ file1.csv
โโโ file2.csv
โโโ file3.csv
4 directories, 3 files
You can specify the region with --region (-r)
. Use the --region
flag to override when you want to specify a region other than the one listed in the profile.
It can also be used with Localstack. When using it with Localstack, the endpoint and region are set to the following by default.
endpoint = http://localhost:4566
region = us-east-1
Since the majority of cases are expected to use the above settings, we have added a flag for Localstack, which is --local (-l)
.
stree my-bucket/test/dir2 -l
In case you need to change the endpoint and region due to special circumstances, you can override with --region (-r)
flag and --endpoint (-e)
.
stree my-bucket/test/dir2 -r us-east-1 -e http://localhost:4537
You can disable color output with --no-color (-n)
.
With color
Without color
You can specify the depth level with --level (-L)
. The default is 0, which means that all directories are displayed.
stree my-bucket -p my_profile -L 3
my-bucket
โโโ test
โโโ dir3
โ โโโ file1.csv
โ โโโ file2.csv
โโโ dir1
โ โโโ dir1_1
โ โโโ dir1_2
โโโ dir2
โโโ dir2_1
You can switch roles with MFA using the --mfa
flag. This makes it easier to manage and view S3 buckets that require different IAM roles for access.
To use this feature, you must first set up the config and credentials to be used with aws cli in advance.
[profile dev_david]
source_profile = my_profile
# MFA device
mfa_serial = arn:aws:iam::820544363308:mfa/david_mfa_device
# Role to assume
role_arn = arn:aws:iam::820544363308:role/david_role
see Assume AWS IAM Roles with MFA Using the AWS SDK for Go for more information
And then execute the following command.
stree my-bucket -p dev_david -mfa
Also, if you wish to operate with a profile that assumes a role, you can specify it using the --profile (-p)
flag, without the need for MFA.
[profile dev_david]
source_profile = my_profile
# Role to assume
role_arn = arn:aws:iam::820544363308:role/david_role
And then execute the following command.
stree my-bucket -p dev_david
Usage:
stree [bucket/prefix] [flags]
Flags:
-e, --endpoint-url string AWS endpoint URL to use (useful for local testing with LocalStack)
-h, --help help for stree
-L, --level int Descend only level directories
-l, --local Use LocalStack configuration
-m, --mfa Use Multi-Factor Authentication
-n, --no-color Disable colorized output
-p, --profile string AWS profile to use (default "default")
-r, --region string AWS region to use (overrides the region specified in the profile)

The concept of "stree" was inspired by the pioneering work seen in gtree. I'm grateful for the inspiration.
