WHAT IS CURL COMMAND?
The curl command is a powerful command line tool used to transfer data to or from a server.
It can use any one of the supported protocols (HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, DICT, TELNET, LDAP or FILE) for data transfer. In many aspects curl is similar to the wget command but curl is more feature rich as compared to wget. The cURL stands for ???See URL???.
The curl command is generally available by default on UNIX systems.
Let’s verify that we have curl installed.
