Description¶

This section explains prominent concepts and notations in the set of high-level S3 commands provided.

Aws services cheat sheet pdfAws Commands Cheat Sheet

Path Argument Type¶

Whenever using a command, at least one path argument must be specified. Thereare two types of path arguments: LocalPath and S3Uri.

LocalPath: represents the path of a local file or directory. It can bewritten as an absolute path or relative path.

S3Uri: represents the location of a S3 object, prefix, or bucket. Thismust be written in the form s3://mybucket/mykey where mybucket isthe specified S3 bucket, mykey is the specified S3 key. The path argumentmust begin with s3:// in order to denote that the path argument refers toa S3 object. Note that prefixes are separated by forward slashes. Forexample, if the S3 object myobject had the prefix myprefix, theS3 key would be myprefix/myobject, and if the object was in the bucketmybucket, the S3Uri would be s3://mybucket/myprefix/myobject.

S3Uri also supports S3 access points. To specify an access point, thisvalue must be of the form s3://<access-point-arn>/<key>. For example ifthe access point myaccesspoint to be used has the ARN:arn:aws:s3:us-west-2:123456789012:accesspoint/myaccesspoint and the objectbeing accessed has the key mykey, then the S3URI used must be:s3://arn:aws:s3:us-west-2:123456789012:accesspoint/myaccesspoint/mykey.Similar to bucket names, you can also use prefixes with access point ARNs forthe S3Uri. For example:s3://arn:aws:s3:us-west-2:123456789012:accesspoint/myaccesspoint/myprefix/

Aws certification cheat sheet

The higher level s3 commands do not support access point object ARNs.For example, if the following was specified:s3://arn:aws:s3:us-west-2:123456789012:accesspoint/myaccesspoint/object/mykeythe S3URI will resolve to the object key object/mykey

Order of Path Arguments¶

Every command takes one or two positional path arguments. The first pathargument represents the source, which is the local file/directory or S3object/prefix/bucket that is being referenced. If there is a second pathargument, it represents the destination, which is the local file/directoryor S3 object/prefix/bucket that is being operated on. Commands with onlyone path argument do not have a destination because the operation is beingperformed only on the source.

Single Local File and S3 Object Operations¶

Some commands perform operations only on single files and S3 objects. Thefollowing commands are single file/object operations if no --recursiveflag is provided.

For this type of operation, the first path argument, the source, must existand be a local file or S3 object. The second path argument, the destination,can be the name of a local file, local directory, S3 object, S3 prefix,or S3 bucket.

The destination is indicated as a local directory, S3 prefix, or S3 bucketif it ends with a forward slash or back slash. The use of slash dependson the path argument type. If the path argument is a LocalPath,the type of slash is the separator used by the operating system. If thepath is a S3Uri, the forward slash must always be used. If a slashis at the end of the destination, the destination file or object willadopt the name of the source file or object. Otherwise, if there is noslash at the end, the file or object will be saved under the name provided.See examples in cp and mv to illustrate this description.

Directory and S3 Prefix Operations¶

Some commands only perform operations on the contents of a local directoryor S3 prefix/bucket. Adding or omitting a forward slash or back slash tothe end of any path argument, depending on its type, does not affect theresults of the operation. The following commands will always result ina directory or S3 prefix/bucket operation:

  • sync
  • mb
  • rb
  • ls

Use of Exclude and Include Filters¶

Currently, there is no support for the use of UNIX style wildcards ina command's path arguments. However, most commands have --exclude'<value>'and --include'<value>' parameters that can achieve the desired result.These parameters perform pattern matching to either exclude or includea particular file or object. The following pattern symbols are supported.

  • *: Matches everything
  • ?: Matches any single character
  • [sequence]: Matches any character in sequence
  • [!sequence]: Matches any character not in sequence

Any number of these parameters can be passed to a command. You can do this byproviding an --exclude or --include argument multiple times, e.g.--include'*.txt'--include'*.png'.When there are multiple filters, the rule is the filters that appear later inthe command take precedence over filters that appear earlier in the command.For example, if the filter parameters passed to the command were

All files will be excluded from the command except for files ending with.txt However, if the order of the filter parameters was changed to

All files will be excluded from the command.

Aws Cli Commands Cheat Sheet

Each filter is evaluated against the source directory. If the sourcelocation is a file instead of a directory, the directory containing the file isused as the source directory. For example, suppose you had the followingdirectory structure:

In the command awss3sync/tmp/foos3://bucket/ the source directory is/tmp/foo. Any include/exclude filters will be evaluated with the sourcedirectory prepended. Below are several examples to demonstrate this.

Given the directory structure above and the commandawss3cp/tmp/foos3://bucket/--recursive--exclude'.git/*', thefiles .git/config and .git/description will be excluded from thefiles to upload because the exclude filter .git/* will have the sourceprepended to the filter. This means that:

The command awss3cp/tmp/foo/s3://bucket/--recursive--exclude'ba*'will exclude /tmp/foo/bar.txt and /tmp/foo/baz.jpg:

Note that, by default, all files are included. This means thatproviding only an --include filter will not change whatfiles are transferred. --include will only re-include files thathave been excluded from an --exclude filter. If you only wantto upload files with a particular extension, you need to first excludeall files, then re-include the files with the particular extension.This command will upload only files ending with .jpg:

If you wanted to include both .jpg files as well as .txt files youcan run:

Available Commands¶

The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.

The AWS CLI v2 offers several new features including improved installers, new configuration options such as AWS Single Sign-On (SSO), and various interactive features.

Windows
Download and run the 64-bit Windows installer.

MacOS
Download and run the MacOS PKG installer.

Linux

  • Fuzzy auto-completion for
    • Commands (e.g. ec2, describe-instances, sqs, create-queue)
    • Options (e.g. --instance-ids, --queue-url)
    • Resource identifiers (e.g. Amazon EC2 instance IDs, Amazon SQS queue URLs, Amazon SNS topic names)
  • Dynamic in-line documentation
    • Documentation for commands and options are displayed as you type
  • Execution of OS shell commands
    • Use common OS commands such as cat, ls, and cp and pipe inputs and outputs without leaving the shell
  • Export executed commands to a text editor

To find out more, check out the related blog post on the AWS Command Line Interface blog.

The AWS Command Line Interface User Guide walks you through installing and configuring the tool. After that, you can begin making calls to your AWS services from the command line.

New file commands make it easy to manage your Amazon S3 objects. Using familiar syntax, you can view the contents of your S3 buckets in a directory-based listing.

You can perform recursive uploads and downloads of multiple files in a single folder-level command. The AWS CLI will run these transfers in parallel for increased performance.

A sync command makes it easy to synchronize the contents of a local folder with a copy in an S3 bucket.

See the AWS CLI command reference for the full list of supported services.
