fping Linux Command Guide
fping is a command-line tool used to quickly ping multiple IP addresses to check their connectivity. It is faster than the traditional ping command and can be used to ping a range of IP addresses as well. Additionally, fping allows for customizing the number of ping packets sent, the time between pings, and can output the results in different formats. This makes it a powerful tool for network administrators and sysadmins to troubleshoot network issues efficiently.
