alternative for netcat utility

Question

Is there any alternative for netcat utility? I want to run docker API and netcat utility is not installed on client system. docker command example - echo -e \"GET /info HTTP/1.0

Answer 1

According to this,

(exec 3<>/dev/tcp/url/port; cat >&3; cat <&3; exec 3<&-)

can replace nc/netcat. It should work in any bash based terminal.

Example:

printf "Hello World!" | (exec 3<>/dev/tcp/termbin.com/9999; cat >&3; cat <&3; exec 3<&-)

returns a link.
