Step 3: Install curl command
In the next step, you can download and install curl utility from default Ubuntu repo by using sudo apt install curl command as shown below. This will download and install the package along with all its dependencies.
cyberithub@ubuntu:~$ sudo apt install curl Reading package lists... Done Building dependency tree... Done Reading state information... Done The following NEW packages will be installed: curl 0 upgraded, 1 newly installed, 0 to remove and 2 not upgraded. Need to get 194 kB of archives. After this operation, 454 kB of additional disk space will be used.

Setting up curl (7.81.0-1ubuntu1.13) ... Processing triggers for man-db (2.10.2-1) ...
Step 4: Verify Installation
After successful installation, you can verify the installed files path by using dpkg -L curl command as shown below.
cyberithub@ubuntu:~$ dpkg -L curl

/usr/bin

Step 5: Check Version
You can also check the current installed version by using curl --version command as shown below.
cyberithub@ubuntu:~$ curl --version curl 7.81.0 (x86_64-pc-linux-gnu) libcurl/7.81.0 OpenSSL/3.0.2 zlib/1.2.11 brotli/1.0.9 zstd/1.4.8 libidn2/2.3.2 libpsl/0.21.0 (+libidn2/2.3.2) libssh/0.9.6/openssl/zlib nghttp2/1.43.0 librtmp/2.3 OpenLDAP/2.5.16 Release-Date: 2022-01-05 Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 pop3s rtmp rtsp scp sftp smb smbs smtp smtps telnet tftp Features: alt-svc AsynchDNS brotli GSS-API HSTS HTTP2 HTTPS-proxy IDN IPv6 Kerberos Largefile libz NTLM NTLM_WB PSL SPNEGO SSL TLS-SRP UnixSockets zstd
Step 6: Using curl
Now that curl is installed in the system, it is time to use it to transfer data with URL. Here we are going to download flutter SDK from official website by using below curl command where -o option is used for specifying the output filename.
cyberithub@ubuntu:~$ curl -o flutter_linux_3.13.0-stable.tar.xz https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_3.13.0-stable.tar.xz

Dload Upload Total Spent Left Speed
100 537M 100 537M 0 0 7487k 0 0:01:13 0:01:13 --:--:-- 7605k
Step 7: Check all the Available Options
You can check all the options available with curl utility by using curl --help command as shown below.
cyberithub@ubuntu:~$ curl --help
Usage: curl [options...] <url>
-d, --data <data> HTTP POST data
-f, --fail Fail silently (no output at all) on HTTP errors
-h, --help <category> Get help for commands
-i, --include Include protocol response headers in the output
-o, --output <file> Write to file instead of stdout
-O, --remote-name Write output to a file named as the remote file
-s, --silent Silent mode
-T, --upload-file <file> Transfer local FILE to destination
-u, --user <user:password> Server user and password
-A, --user-agent <name> Send User-Agent <name> to server
-v, --verbose Make the operation more talkative
-V, --version Show version number and quit
This is not the full help, this menu is stripped into categories.
Use "--help category" to get an overview of all categories.
For all options use the manual or "--help all".
Step 8: Uninstall curl command
Once you are done using curl tool, you can choose to uninstall it from your system by using sudo apt remove curl command as shown below.
cyberithub@ubuntu:~$ sudo apt remove curl Reading package lists... Done Building dependency tree... Done Reading state information...

If you are looking to remove curl utility along with all its dependencies then you need to run sudo apt remove curl --auto-remove command as shown below.
cyberithub@ubuntu:~$ sudo apt remove curl --auto-remove Reading package lists... Done Building dependency tree... Done Reading state information...
