Pronounce an English word using Merriam-Webster.com
Looks up a word on merriam-webster.com, does a screen scrape for the FIRST audio pronunciation and plays it. USAGE: Put this one-liner into a shell script (e.g., ~/bin/pronounce) and run it from the command line giving it the word to say: $ pronounce lek If the word isn't found in merriam-webster, no audio is played and the script returns an error value. However, M-W is a fairly complete dictionary (better than howjsay.com which won't let you hear how to pronounce naughty words). ASSUMPTIONS: GNU's sed (which supports -r for extended regular expressions) and Linux's aplay. Aplay can be replaced by any program that can play .WAV files from stdin. KNOWN BUGS: only the FIRST pronunciation is played, which is problematic if you wanted a particular form (plural, adjectival, etc) of the word. For example, if you run this: $ pronounce onomatopoetic you'll hear a voice saying "onomatopoeia". Playing the correct form of the word is possible, but doing so might make the screen scraper even more fragile than it already is. (The slightest change to the format of m-w.com could break it).

Create a DOS floppy image
mount with: mount -t msdos -o loop ./floppy.img /tmp/mnt

Rsync files with spaces
Using the double dash before the source and target makes the command work fine with weird filenames.

Length of longest line of code
Here's an awk version.

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" }

find an unused unprivileged TCP port
Not really better - just different ;) There's probably a really simple solution out there somewhere...

Display all readline binding that use CTRL
Useful for getting to know the available keyboard shortcuts.

convert a mp4 video file to mp3 audio file (multiple files)

Create a file server, listening in port 7000
At client side: tar c myfile | nc localhost 7000 ##Send file myfile to server tar c mydir | nc localhost 7000 ## Send directory mydir to server

rename files according to file with colums of corresponding names
Maybe simpler, but again, don't know how it will work with space in filename.
