IFDATA(1)

💖 IFDATA(1) 💖

okay bestie, so this is ifdata, and it lives in the moreutils manual, section 1. yes, that moreutils. the little grab-bag of tools that goes absolutely feral. and ngl, this one is lowkey the moment.

✨ NAME ✨

ifdata — get network interface info without parsing ifconfig output 🦋

🌸 SYNOPSIS 🌸

ifdata [options] {iface}

🎀 DESCRIPTION 🎀

so here's the vibe: ifdata can check if a network interface even exists, or it can spill the tea about that interface — like its IP address, etc.

and here's the part that ate 💅 — unlike ifconfig or ip, ifdata gives you simple to parse output that is literally designed to be easily used by a shell script. it's giving "written by someone who has suffered through awk-ing ifconfig output at 3am." main character energy fr fr.

💖 OPTIONS 💖

• -h — print out a help summary. cute, quick, we love a summary.
• -e — test to see if the interface exists. exits nonzero if it does not. a little vibe check for your interface, basically. 😌
• -p — prints out the whole configuration of the interface. the full lore drop.
• -pe — prints "yes" or "no" depending on whether the interface exists or not.
• -pa — prints the IPv4 address of the interface.
• -pn — prints the netmask of the interface.
• -pN — prints the network address of the interface. (capital N, bestie, don't mix it up with -pn 👀)
• -pb — prints the broadcast address of the interface.
• -pm — prints the MTU of the interface.

🌈 heads up: the following options are Linux only. no cap.

• -ph — prints the hardware address of the interface. exits with a failure exit code if there is not a hardware address for the given network interface. 😭
• -pf — prints the flags of the interface.
• -si — prints out all the input statistics of the interface. the whole input saga.
• -sip — prints the number of input packets.
• -sib — prints the number of input bytes.
• -sie — prints the number of input errors.
• -sid — prints the number of dropped input packets.
• -sif — prints the number of input fifo overruns.
• -sic — prints the number of compressed input packets.
• -sim — prints the number of input multicast packets.
• -so — prints out all the output statistics of the interface. and now the output saga ✨
• -sop — prints the number of output packets.
• -sob — prints the number of output bytes.
• -soe — prints the number of output errors.
• -sod — prints the number of dropped output packets.
• -sof — prints the number of output fifo overruns.
• -sox — prints the number of output collisions.
• -soc — prints the number of output carrier losses.
• -som — prints the number of output multicast packets.
• -bips — prints the number of bytes of incoming traffic measured in one second. bytes-in-per-second, iykyk 🍓
• -bops — prints the number of bytes of outgoing traffic measured in one second.
