-mrt, -match-response-time string  match response with specified response time in seconds (-mrt '< 1')
-frt, -filter-response-time string  filter response with specified response time in seconds (-frt '> 1')

Hi @LuitelSamikshya,

Could you please include an example using response-based matcher/filter? also we can include the time unit used with matcher/filter in CLI flag description, which supposed to be in second in this case.

chaos -d hackerone.com | ./httpx  -mrt '> 1' -silent
[FTL] invalid value provided for -mrt, -match-response-time

Sure, here are some examples:
./httpx -l list.txt -silent -mrt ">=2"
./httpx -l list.txt -silent -frt ">1"

• Use https://github.com/dustin/go-humanize to express units (eg 2s, 200ms)
• Add tests
