Shell function to create a menu of items which may be inserted into the X paste buffer.

The function will take a comma separated list of items to be 'selected' by xsel -i: smenu "First item to paste,Paste me #2,Third menu item" You will then be prompted to choose one of the menu items. After you choose, you will be able to paste the string by clicking the middle mouse button. The menu will keep prompting you to choose menu items until you break out with Control-C.

Pipe text from shell to windows cut and paste buffer using PuTTY and XMing.

Set up X forwarding in PuTTY, with X display location set to :0.0 Launch PuTTY ssh session. Launch Xming. Make sure that display is set to :0.0 (this is default). echo "I'm going to paste this into WINDERS XP" | xsel -i will insert the string into the windows cut and paste buffer.

Recursively search a directory tree for all .php .inc .html .htm .css .js files for a certain string

Use find to recursively make a list of all files from the current directory and downwards. The files have to have an extension of the ones listed. Then for every file found, grep it for 'searchString', returns the filename if searchString is found. Show Sample Output

Getting involved!!

I absolutely love this website, and appreciate every contribution. This is the first place I go when I'm stuck, you all have some great ideas. But contributions seem to be slipping a little. If all of us could contribute more code from time to time, this site would be absolutely incredible. Since I'm a relative newcomer to commandline-fu, I don't have the knowledge to contribute much, but I will do what I can.

Add line number count as C-style comments

I often find the need to number enumerations and other lists when programming. With this command, create a new file called 'inputfile' with the text you want to number. Paste the contents of 'outputfile' back into your source file and fix the tabbing if necessary. You can also change this to output hex numbering by changing the "%02d" to "%02x". If you need to start at 0 replace "NR" with "NR-1". I adapted this from http://osxdaily.com/2010/05/20/easily-add-line-numbers-to-a-text-file/.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Get first Git commit hash

docker kill all containers

complete extraction of a debian-package

extracts the debian-package $debfile to $extractdir, including all packaging-information. to repack the package, just type: $dpkg-deb -b $extractdir

tcmdump check ping

capture only ping echo requests with tcpdump

Recursive cat - concatenate files (filtered by extension) across multiple subdirectories into one file

Useful if you have to put together multiple files into one and they are scattered across subdirectories. For example: You need to combine all .sql files into one .sql file that would be sent to DBAs as a batch script. You do get a warning if you create a file by the same extension as the ones your searching for. find . -type f -name *.sql -exec cat {} > BatchFile.txt \;

Steve Reich - Piano Phase; interpreter: Bourne-Again Shell.

The Piano Phase piece, by Steve Reich is a minimalist composition which is played on two pianos played at slightly different tempos, a task that's very difficult to accomplish by human players. The auditive effects produced by the cell displacement produce beautiful patterns. See https://en.wikipedia.org/wiki/Piano_Phase . My rendered version: https://ydor.org/SteveReich/piano_phase.mp3 Requires sox to be installed on the system. There are multiple videos on youtube showing different approaches and experiences to this interpretation. There is also a synthesized version. Even if Bash can behave as a powerful pianist, a simple threaded version leaves full room to several time glitches and even negative displacements, the same issues that human pianists experience when playing the piece. The older the computer, the better the chaos added to the result due to the CPU load. Apparently that's the reason Steve Reich composes pieces such as this. Without further ado, please give a warm welcome to the Bash minimalist player on synthesized two-threaded pianos. Please turn off your cellphones.
