  • The ebay URL is the search query copied from the browser (here searching for bed stuff). The regex is for crap that should not be shown. Important is "Pickup only", which filters away all the things that cannot be shipped (a filter that cannot be done on Ebay's webpage). It will output the title and url for all matching items, for all pages of the search result. It also works for the German Ebay. Show Sample Output

    xidel --quiet '' -e 'css(".lvresult")[not(matches(., "Pickup only|BUILDING PLANS \(ONLY\)|PARTS LIST"))]/css(".lvtitle")/(.||": "||a/@href)' -f 'css("")'

  • This logs the titles of the active windows, thus you can monitor what you have done during which times. (it is not hard to also log the executable name, but then it is gets too long) Show Sample Output

    while true; do (echo -n $(date +"%F %T"):\ ; xwininfo -id $(xprop -root|grep "ACTIVE_WINDOW("|cut -d\ -f 5) | grep "Window id" | cut -d\" -f 2 ) >> logfile; sleep 60; done

  • 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- $(xidel "$*" -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

    pronounce(){ xidel "$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -f 'css("embed")[1]/@src' --download - | aplay -q;}

What's this? is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

cd up a number of levels
Instead of typing "cd ../../.." you can type ".. 3". For extremely lazy typists, you can add this alias: alias ...=".. 2" ....=".. 3" - so now you can write just .... !!! NB the .. function needs to be "source"d or included in your startup scripts, perhaps .bashrc.

Cut the first 'N' characters of a line
Saves one character, the original is probably clearer

Make a DVD ISO Image from a VIDEO_TS folder on MacOSX
/path/ is the root folder of the DVD, not the VIDEO_TS folder.

When a fs hangs and you've just one console, even # ls could be a dangerous command. Simply put a trailing "&" and play safe

Second pass dvd rip... The set of commands was too long, so I had to separate them into two.
This set of commands will rip a dvd title using a 2 pass mencoder xvid encode. It will provide a great quality rip. It will rip as close to 700MB as possible. (note the bitrate of -700000) Enjoy!

Connect to SMTP server using STARTTLS
