> [!IMPORTANT]
> Opting for this installation method means you'll have to repeat this manual process to update the CLI to a newer release!
[Explore the available versions](https://github.com/jsdelivr/globalping-cli/releases).
## Updating
If you've installed the Globalping CLI via a package manager, you only need to run the manager's update command to get the latest Globalping CLI version.
## Getting started with Globalping CLI
After installing, verify the Globalping CLI is working by running:
`globalping --help`
The result shows how to use the CLI and which commands and flags are available:
```
Usage:
globalping [command]
Measurement Commands:
dns Resolve DNS records, similar to the dig command
http Perform a HEAD or GET request to a host
mtr Run a MTR test, which combines traceroute and ping
ping Perform a ping test
traceroute Run a traceroute test
Additional Commands:
completion Generate the autocompletion script for the specified shell
help Help about any command
history Display the measurement history of your current session
install-probe Join the Globalping network by running a probe
version Display the version of your installed Globalping CLI
Flags:
-C, --ci disable real-time terminal updates and colors, suitable for CI and
scripting (default false)
-F, --from string specify the probe locations as a comma-separated list; you may use:
- names of continents, regions, countries, US states, cities, or
networks
- [@1 | first, @2 ... @-2, @-1 | last | previous] to run with the probes
from previous measurements in this session
- an ID of a previous measurement to run with its probes
(default "world")
-h, --help help for globalping
-4, --ipv4 resolve names to IPv4 addresses
-6, --ipv6 resolve names to IPv6 addresses
-J, --json output results in JSON format (default false)
--latency output only the latency stats; applicable only to dns, http, and ping
commands (default false)
-L, --limit int define the number of probes to use (default 1)
--share print a link at the end of the results to visualize them online (default
false)
Use "globalping [command] --help" for more information about a command.
```
### Run your first tests
Globalping relies on a community-hosted probe network, enabling you to run network tests from any location with an active probe. The following examples show you through some tests, exploring how to define locations, set limits, and use some command flags.
#### Filter locations
For example, if you want to run ping from a probe in Seattle that is also part of the Comcast network, run the following:
```bash
globalping ping google.com from Comcast+Seattle
> Seattle (WA), US, NA, Comcast Cable Communications, LLC (AS33650)
PING (142.250.217.78) 56(84) bytes of data.
64 bytes from sea09s29-in-f14.1e100.net (142.250.217.78): icmp_seq=1 ttl=58 time=14.0 ms
64 bytes from sea09s29-in-f14.1e100.net (142.250.217.78): icmp_seq=2 ttl=58 time=14.5 ms
64 bytes from sea09s29-in-f14.1e100.net (142.250.217.78): icmp_seq=3 ttl=58 time=15.9 ms
--- ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 402ms
rtt min/avg/max/mdev = 13.985/14.779/15.886/0.807 ms
```
You can use the `+` symbol as a filter to select the desired location of the probes more precisely.
> [!TIP]
> You can mix and match any location type, including countries, continents, cities, US states, regions, ASNs, ISP names, eyeball or data center tags, and cloud region names.
#### Define multiple locations and basic flags
With the following command, we execute four ping commands at four different locations and obtain the summarized latency metrics for each test as a result:
```bash
globalping ping google.com from Amazon,Germany,USA,Dallas --limit 4 --latency
> Seoul, KR, AS, Amazon.com, Inc. (AS16509) (aws-ap-northeast-2)
Min: 33.163 ms
Max: 33.256 ms
Avg: 33.22 ms
> Frankfurt, DE, EU, DE, OVH SAS (AS16276)
Min: 1.221 ms
Max: 1.291 ms
Avg: 1.264 ms
> Chicago (IL), US, NA, Cogent Communications (AS174)
Min: 112.405 ms
Max: 112.686 ms
Avg: 112.528 ms
> Dallas (TX), US, NA, Catalyst Host LLC (AS393336)
Min: 1.579 ms
Max: 1.588 ms
Avg: 1.584 ms
```
You can select multiple locations for running a command by using a comma `,` as a delimiter. When doing so, make sure to also specify the number of tests to run with the `--limit` flag.
For example, to run ping from four different locations (as we did in the example above), add `--limit 4` to make sure you get one test result per location. Otherwise, the default limit of 1 will be selected, resulting in a random result from one of the four locations.
Finally, you can use the `--latency` parameter to only get the summarized latency data instead of the full raw output.
> [!TIP]
> We recommend reading our [tips and best practices](https://github.com/jsdelivr/globalping#best-practices-and-tips) to learn more about defining locations effectively!
#### Share results online
Include a link at the bottom of your results using the `--share` flag to view and share the test results online.
> [!IMPORTANT]
> Shareable links and the respective saved measurement results expire after a few weeks, depending on the user type. GitHub Sponsors, for example, enjoy extended result storage.
```bash
globalping dns google.com from gcp-asia-south1 --share
> Mumbai, IN, AS, Google LLC (AS396982) (gcp-asia-south1)

#### Reselect probes
You can select the same probes used in a previous measurement by passing the measurement ID to the `--from` flag.

#### Reselect probes from measurements in the current session
Use `[@1 | first, @2 ... @-2, @-1 | last | previous]` to select the probes from previous measurements in the current session.
```bash
globalping ping google.com from USA --latency
> Ashburn (VA), US, NA, Hetzner Online GmbH (AS213230)
Min: 7.314 ms
Max: 7.413 ms
Avg: 7.359 ms
globalping ping google.com from Germany --latency
> Falkenstein, DE, EU, Hetzner Online GmbH (AS24940)
Min: 4.87 ms
Max: 4.936 ms
Avg: 4.911 ms
globalping ping google.com from previous --latency
> Falkenstein, DE, EU, Hetzner Online GmbH (AS24940)
Min: 4.87 ms
Max: 4.936 ms

Min: 7.314 ms
Max: 7.413 ms
Avg: 7.359 ms
```
#### Continuous non-stop measurements
> [!IMPORTANT]
> Currently this feature is limited to the ping command
You can use the `--infinite` flag to continuously ping a host, just like on Linux or MacOS.
Note that while it looks like a single measurement, in actuality its multiple measurements from the same probes combined into a single output.
This means that eventually you will run out of credits and the test will stop.
```bash
globalping ping cdn.jsdelivr.net from Europe --infinite
> London, GB, EU, Psychz Networks (AS40676)
PING cdn.jsdelivr.net (151.101.1.229) 56(84) bytes of data.
64 bytes from 151.101.1.229 (151.101.1.229): icmp_seq=1 ttl=59 time=0.54 ms
64 bytes from 151.101.1.229 (151.101.1.229): icmp_seq=2 ttl=59 time=0.42 ms
^C
```
If you select multiple probes when using `--infinite` the output will change to a summary comparison table.
```bash
globalping ping cdn.jsdelivr.net from Europe --limit 5 --infinite
Location | Sent | Loss | Last | Min | Avg | Max
London, GB, EU, OVH SAS (AS16276) | 22 | 0.00% | 3.33 ms | 3.07 ms | 3.20 ms | 3.33 ms
Falkenstein, DE, EU, Hetzner Online GmbH (AS24940) | 22 | 0.00% | 5.41 ms | 5.30 ms | 5.78 ms | 13.1 ms
Vienna, AT, EU, EDIS GmbH (AS57169) | 22 | 0.00% | 0.47 ms | 0.46 ms | 0.56 ms | 0.88 ms
Stockholm, SE, EU, The Constant Company, LLC (AS20473) | 22 | 0.00% | 1.03 ms | 0.83 ms | 1.15 ms | 4.66 ms
Madrid, ES, EU, EDGOO NETWORKS LLC (AS47787) | 22 | 0.00% | 0.24 ms | 0.13 ms | 0.26 ms | 0.42 ms
^C
```
#### History
You can view the history of your measurements by running the `history` command.
```bash
globalping history

> https://www.jsdelivr.com/globalping?measurement=itcR65tYCqbouXib

#### Learn about available flags
Most commands have shared and unique flags. We recommend that you familiarize yourself with these so that you can run and automate your network tests in powerful ways.
Simply execute the command you want to learn more about with the `--help` flag:
