recursive version, "pure" AWK Show Sample Output
This will save your open windows to a file (~/.windows).
To start those applications:
cat ~/.windows | while read line; do $line &; done
Should work on any EWMH/NetWM compatible X Window Manager.
If you use DWM or another Window Manager not using EWMH or NetWM try this:
xwininfo -root -children | grep '^ ' | grep -v children | grep -v '<unknown>' | sed -n 's/^ *\(0x[0-9a-f]*\) .*/\1/p' | uniq | while read line; do xprop -id $line _NET_WM_PID | sed -n 's/.* = \([0-9]*\)$/\1/p'; done | uniq -u | grep -v '^$' | while read line; do ps -o cmd= $line; done > ~/.windows

I've been using it in a script to build from scratch proxy servers. Show Sample Output
Interfaces like lo can be omitted from the beginning, there are probably better ways of doing this, i'm a noob at awk. Show Sample Output
Yet another x11grab using ffmpeg. I also added mic input to the capturing video stream using alsa. Yet I need to find out how to capture audio which is currently playing. Show Sample Output
ifconfig can't properly display interface's name longer 9 symbols,also it can't show IPs added thru ip command, so 'ip' should be used instead. This alias properly shows long names, bond interfaces and all interface aliases. loopback interface is ignored, since its IP is obvious Show Sample Output
This command loops over all of the processes in a system and creates an associative array in awk with the process name as the key and the sum of the RSS as the value. The associative array has the effect of summing a parent process and all of it's children. It then prints the top ten processes sorted by size. Show Sample Output
Get your weather from a weather station just blocks from your home. Go to http://www.wunderground.com/wundermap/ and find a weather station near you. Click on a temperature bubble for that area. When the window pops up, click on hypertext link with the station ID, then on the bottom right of the page, click on the Current Conditions XML. Thats your link! Good luck! Show Sample Output
Uses the dumb terminal option in gnuplot to plot a graph of frequencies. In this case, we are looking at a frequency analysis of words in all of the .c files. Show Sample Output
You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds. Someone better at awk could probably reduce this down a lot. Show Sample Output
I sometimes (due to mismanagement!) end up with files in a git repo which have had their modes changed, but not their content. This one-liner lets me revert the mode changes, while leaving changed-content files be, so I can commit just the actual changes made.
shows also time if its the same year or shows year if installed before actual year and also works if /etc is a link (mac os) Show Sample Output
% cat ph-vmstat.awk # Return human readable numbers function hrnum(a) { b = a ; if (a > 1000000) { b = sprintf("%2.2fM", a/1000000) ; } else if (a > 1000) { b = sprintf("%2.2fK", a/1000) ; } return(b) ; } # Return human readable storage function hrstorage(a) { b = a ; if (a > 1024000) { b = sprintf("%2.2fG", a/1024/1024) ; } else if (a > 1024) { b = sprintf("%2.2fM", a/1024) ; } return(b) ; } OFS=" " ; $1 !~ /[0-9].*/ {print} $1 ~ /[0-9].*/ { $4 = hrstorage($4) ; $5 = hrstorage($5) ; $9 = hrnum($9) ; $10 = hrnum($10) ; $17 = hrnum($17) ; $18 = hrnum($18) ; $19 = hrnum($19) ; print ; } Show Sample Output
List files above a given size threshold. Show Sample Output
Are there any creative pieces of music that can be created using beep and the shell? I'd love to hear it!
This command will kill all processes using a directory. It's quick and dirty. One may also use a -9 with kill in case regular kill doesn't work. This is useful if one needs to umount a directory. Show Sample Output
Pick a mp3 at random and play it. Assumes the availability of locate with an updated db and mpg123 Not the most useful command I guess, but all of the really useful ones are taken...
Note that the file at the given path will have the contents of the (still) deleted file, but it is a new file with a new node number; in other words, this restores the data, but it does not actually "undelete" the old file. I posted a function declaration encapsulating this functionality to http://www.reddit.com/r/programming/comments/7yx6f/how_to_undelete_any_open_deleted_file_in_linux/c07sqwe (please excuse the crap formatting).
