  • Monitor Applications application that are connected/new connections

    The -p parameter tell the netstat to display the PID and name of the program to which each socket belongs or in digestible terms list the program using the net.Hope you know what pipe symbol means! Presently we wish to only moniter tcp connections so we ask grep to scan for string tcp, now from the op of grep tcp we further scan for regular expression /[a-z]*. Wonder what that means ? If we look at the op of netstat -p we can see that the name of the application is preceded by a / ( try netstat -p ) so,now i assume application name contains only characters a to z (usually this is the case) hope now it makes some sense.Regular expression /[a-z]* means to scan a string that start with a / and contains zero or more characters from the range a-z !!. Foof .. is t Show Sample Output


    -4
    while true; do netstat -p |grep "tcp"|grep --color=always "/[a-z]*";sleep 1;done

  • netstat -p recoded (totaly useless..)

    Ok so it's rellay useless line and I sorry for that, furthermore that's nothing optimized at all... At the beginning I didn't managed by using netstat -p to print out which process was handling that open port 4444, I realize at the end I was not root and security restrictions applied ;p It's nevertheless a (good ?) way to see how ps(tree) works, as it acts exactly the same way by reading in /proc So for a specific port, this line returns the calling command line of every thread that handle the associated socket


    -5
    p=$(netstat -nate 2>/dev/null | awk '/LISTEN/ {gsub (/.*:/, "", $4); if ($4 == "4444") {print $8}}'); for i in $(ls /proc/|grep "^[1-9]"); do [[ $(ls -l /proc/$i/fd/|grep socket|sed -e 's|.*\[\(.*\)\]|\1|'|grep $p) ]] && cat /proc/$i/cmdline && echo; done

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Check These Out

Uniquely (sort of) color text so you can see changes
Colorify colors input by converting the text to a number and then performing modulo 7 on it. This resulting number is used as the color escape code. This can be used to color the results of commands with complex outputs (like "482279054165371") so if any of the digits change, there's a good chance the color will change too. I say good chance because there's only 7 unique colors here, so assuming you were watching random numbers, there would be a 6/7 chance that the color would change when the number changed. This should really only be used to help quickly identify when things change, but should not be the only thing relied upon to positively assert that an output has not changed.

Short URLs with is.gd
No curl and no sed, just wget :)

Watch the progress of 'dd'
Only slightly different than previous commands. The benefit is that your "watch" should die when the dd command has completed. (Of course this would depend on /proc being available)

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

dump database from postgresql to a file

Check your unread Gmail from the command line
Just an alternative with more advanced formating for readability purpose. It now uses colors (too much for me but it's a kind of proof-of-concept), and adjust columns.

execute your commands and avoid history records
$ secret_command;export HISTCONTROL= This will make "secret_command" not appear in "history" list.

Erase a word
hit BACKSPACE more than once to delete more words

UPS Tracking Script

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously
