Pronounce an English word using Merriam-Webster.com

Updated to the new version of the MW webpage (seems MW does not use cougar anymore, so the other commands do not work nowadays), and using Xidel to parse the page with a html parser instead regex. Example usage: pronounce onomatopoetic I'm not sure how well Xidel works with binary streams (although it seems to work great in tests), so using wget to download the actual wav file might be safer, i.e.: pronounce(){ wget -qO- $(xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -e 'css("embed")[1]/@src') | aplay -q;} Xidel is not a standard cli tool and has to be downloaded from xidel.sourceforge.net

Pronounce an English word using Merriam-Webster.com

The original was a little bit too complicated for me. This one does not use any variables.

Make sure a script is run in a terminal.

If your script needs to be run in a terminal, this line at the top will stop it running if you absent-mindedly double-click the icon, perhaps intending to edit it. (Of course this won't help with scripts that run in the background.)

Show File System Hierarchy

Curious about differences between /bin, /usr/bin, and /usr/local/bin? What should be in the /sbin dir? Try this command to find out. Tested against Red Hat & OS X

Display or use a random file from current directory via a small bash one-liner

An other way to run it ( playing a random file ending with avi, flv or mpeg ) from a specified dir and a specified type of extension : making MOVIE array with a glob : $ MOVIE=( /PATH/TO/MY/FAVORITE/MOVIES/*.{avi,flv,mpeg} ) playing the random file from a random key from the array $ mplayer ${MOVIE[ RANDOM % ( ${#i[@]} + 1 ) ]]} I use only globs and a bash array. I use GNU bash, version 3.2.48

Find Duplicate Files, excluding .svn-directories (based on size first, then MD5 hash)

Improvement of the command "Find Duplicate Files (based on size first, then MD5 hash)" when searching for duplicate files in a directory containing a subversion working copy. This way the (multiple dupicates) in the meta-information directories are ignored. Can easily be adopted for other VCS as well. For CVS i.e. change ".svn" into ".csv": $ find -type d -name ".csv" -prune -o -not -empty -type f -printf "%s\n" | sort -rn | uniq -d | xargs -I{} -n1 find -type d -name ".csv" -prune -o -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 --all-repeated=separate

download and unpack tarball without leaving it sitting on your hard drive

Join lines and separate with spaces

Read vmargs.txt, which is a text file that could either be DOS-style (\r\n) or UNIX-style (\n) line endings and join the lines with a space separator. Can this be shortened/made more elegant?

Simplest way to get size (in bytes) of a file

Stop All Wine Apps and Processes
