Another way of counting the line output of tail over 10s not requiring pv. Cut to have the average per second rate : tail -n0 -f access.log>/tmp/tmp.log & sleep 10; kill $! ; wc -l /tmp/tmp.log | cut -c-2 You can also enclose it in a loop and send stderr to /dev/null : while true; do tail -n0 -f access.log>/tmp/tmp.log & sleep 2; kill $! ; wc -l /tmp/tmp.log | cut -c-2; done 2>/dev/null

Displays the realtime line output rate of a logfile. -l tels pv to count lines -i to refresh every 10 seconds -l option is not in old versions of pv. If the remote system has an old pv version: ssh tail -f /var/log/apache2/access.log | pv -l -i10 -r >/dev/null

or "Execute a command with a timeout" Run a command in background, sleep 10 seconds, kill it. ! is the process id of the most recently executed background command. You can test it with: find /& sleep10; kill $!

kaffeine could be replaced by any player able to read mms stream

Need to have rc iso pre-downloaded before running command.

Tested with 9.10 release. Choose whatever torrent client you prefer.

The cut should match the relevant timestamp part of the logfile, the uniq will count the number of occurrences during this time interval. Show Sample Output

Change the cut range for hits per 10 sec, minute and so on... Grep can be used to filter on url or source IP. Show Sample Output

awk is evil! Show Sample Output

There's another version on here that uses GET but some people don't have lwp-request, so here's an alternative. It's also a little shorter and should work with most youtube URLs since it truncates at the first &

This is a very simple and lightweight way to play DI.FM stations For a more complete version of the command with proper strings in the menu, try: (couldnt fit in the command field above) zenity --list --width 500 --height 500 --title 'DI.FM' --text 'Pick a Radio' --column 'radio' --column 'url' --print-column 2 $(curl -s http://www.di.fm/ | awk -F '"' '/href="http:.*\.pls.*96k/ {print $2}' | sort | awk -F '/|\.' '{print $(NF-1) " " $0}') | xargs mplayer This command line parses the html returned from http://di.fm and display all radio stations in a nice graphical menu. After the radio is chosen, the url is passed to mplayer so the music can start dependencies: - x11 with gtk environment - zenity: simple app for displaying gtk menus (sudo apt-get install zenity on ubuntu) - mplayer: simple audio player (sudo apt-get install mplayer on ubuntu) Show Sample Output

enumerates the number of processes for each user. ps BSD format is used here , for standard Unix format use : ps -eLf |awk '{$1} {++P[$1]} END {for(a in P) if (a !="UID") print a,P[a]}' Show Sample Output

Useful command to get information about running java process and treads, to see log look into the default log for your java application

Gives you a nice quick summary of how many lines each of your files is comprised of. (In this example, we just check .c, .h, .php and .pl). Since we just use wc -l to count, you'll just get a very rough estimate of how many lines of actual code there are. Use a more sophisticated algorithm instead if you need to. Show Sample Output

The above command will set the GID bit on all directories named .svn in the current directory recursively. This makes the group ownership of all .svn folders be the group ownership for all files created in that folder, no matter the user. This is useful for me as the subversion working directory on my server is also the live website and needs to be auto committed to subversion every so often via cron as well as worked on by multiple users. Setting the GID bit on the .svn folders makes sure we don't have a mix of .svn metadata created by a slew of different users.

This will search all directories and ignore the CVS ones. Then it will search all files in the resulting directories and act on them.

The options -b binary and -m are needed for disassembling raw machine code when it is not part of a full binary executable with proper headers. Show Sample Output

This is N5 sorta like rot13 but with numbers only. Encrypt echo "$1" | xxd -p | tr '0-9' '5-90-6' Decrypt echo "$1" | tr '0-9' '5-90-6' | xxd -r -p Show Sample Output

Starts the cursor on line X of file foo. Useful for longer files in which it takes a long time to scroll. If X is greater than the number of lines in file foo, it will go to the last existing line.

Possible simplification of egrep-awk-sort with find and -exec with xargs. Show Sample Output
