  • I run into regular problems whereby my cable modem from my ISP will simply stop working. To ensure that it is a problem with my cable modem (and not the router in-between my machine and the cable modem), I needed a quick way to test to someplace beyond the cable modem. The place shouldn't be beyond the cable network though. As such, I needed to determine the gateway to which my cable modem was connected. Since my router cannot do this on it's own... I created a single line command that will ping the gateway IP address based upon knowing that my gateway will be my second hop (after my wifi router), tracerouting for 2 hops, pulling the last line of the traceroute output and grep'ing for just the IP address. To stop pinging, use . This works on linux and osx and, with the addition of cygwin tools or the win-gnu project... should work on windows as well. Show Sample Output

  • In the vein of "can you do it better", here is my take on using "ping" to emulate sleep in a DOS/BAT script. If one can use ping at all then the multicast address will be valid but will not respond. By doing only one ping (-n 1) and setting a timeout in milliseconds (-w 10000) you have a fairly accurate timer. This example gives about a 10 second sleep.

    ping -n 1 -w 10000 224.0.0.0

  • Does one ping to a URL or host, and echo out just the response time. I use this on, with MRTG to monitor the connections to various hosts. Show Sample Output


    -1
    ping -c 1 www.google.com | /usr/bin/awk '{print $7}' | /usr/bin/awk 'NR > 1' | /usr/bin/awk 'NR < 2' | /usr/bin/awk -F"=" '{print $2}'

  • A simple way to find all machines on a network subnet is pinging a broadcast address (-b flag). First run ifconfig ifconfig. Then use "Bcast" address and '-b' flag in ping Show Sample Output


    -1
    ping -b <broadcast address>

  • If you need to ssh into a computer on the local network but you're unsure of the ip to use, then ping them and see if you get a response. If you do, print out the address you got it from. Adjust the range to suit your network.

    for i in 192.168.1.{61..71};do ping -c 1 $i &> /dev/null && echo $i;fi;done

  • Not really an easier solution. But an example using && for (if last command returned 0). You can use || for (if last command returned other than 0).. Show Sample Output


    -2
    prefix="10.0.0" && for i in `seq 25`; do ping -c 1 $prefix.$i &> /dev/null && echo "Answer from: $prefix.$i" ; done

  • Every 20 minutes ping host with IP address 192.168.0.14. If it's not 'alive' or not reachable, then display something eye-catching (here xeyes) on the desktop. Hint for newbies: edit crontab with crontab -e

    10,30,50 * * * * ping -q -c1 -w3 192.168.0.14 | grep '1 received' - || env DISPLAY=:0 xeyes

  • On Linux and Mac systems (I have not tested with other Unix systems), the ping command will keep on pinging until the user interrupts it with Ctrl+C. On Windows system, ping will execute for a number of times then quit. The -c flag on Linux and Mac will make this happen

    ping -c 10 hostname

  • Every 20 minutes test if host with IP 192.168.0.14 is 'dead' or not reachable. The line should be put in your crontab file.

  • Say you need to ping every 5th IP address on your network .. this will give you a way of doing that. jot can also do counting ... like jot 4 1 2 3 4 download from http://oreilly.com/catalog/upt2/examples/#jot or fins athena-jot in rpm format Show Sample Output

Remove the first character of each line in a file

Download all images from a site
This recursively downloads all images from a given website to your /tmp directory. The -nH and -nd switches disable downloading of the directory structure.

search installed files of package, that doesn't remember his name well. On rpm systems
rpm, sometimes, is not wildcard friendly. To search files installed from package this could be useful. change PACKAGENAME to any package do you want to search

find files containing text
-l outputs only the file names -i ignores the case -r descends into subdirectories

Open browser from terminal to create PR after pushing something in Git in MAC

recursive transform all contents of files to lowercase
In this way it doesn't have problems with filenames with spaces.
