Get http://xkcd.com/now image, inverts colors (I prefer dark backgrounds) and set it as wallpaper.

You can replace the "convert" part by "wget -q http://imgs.xkcd.com/comics/now.png -O /tmp/now.png" if you prefer light backgrounds.

The DISPLAY variable is here to work as a cron job.

Took one of the samples, added capitalization and removes in between spaces.

The final "echo" is just for readability.

this assumes that all comics are saved as xkcd-[number]-[title].{png|jpg}.

it will then download the title and alt-text, create pictures from them, and put everything together in a new png-file.

it's not perfect, but it worked for nearly all my comics.

it uses the xkcd-json-interface.

though it's poorly written, it doesn't completely break on http://xkcd.com/859/

This restricts things 3 ways:

1. No capitalized words, hence no proper names.

2. No apostrophes.

3. Restricts size to range (3,7)

Some snippets posted are slow on big dictionaries, this one is fast.

This does the same thing that the command 'j_melis' submitted, but does it a lot quicker.

That command takes 43 seconds to complete on my system, while the command I submitted takes 6 seconds.

The improvement of this command over Strawp's original alternative is that you can specify the size of the words, in this particular case words between 3 and 5 character's long. It also excludes words that contain apostrophes, if you'd rather keep those words simply substitue [^'] for .

awk 'BEGIN {srand} /^[a-z]{4,8}$/ {w[i++]=$0} END {while (j++<4) print w[int(rand*i)]}' /usr/share/dict/words

If you do not have shuf or an -R option in sort, you can fall back on awk. This provides maximum portability IMO. The command first collects words from the dictionary that match the criteria - in this case: lower case words with no punctuation that are 4 to 8 characters long. It then prints 4 random entries. I decided to print each word on a separate line to improve readability.

sort -R /usr/share/dict/british | grep -v -m4 ^\{1,10\}$ | tr [:upper:] [:lower:] | tr "\n" " " | tr -d "'s" | xargs -0 echo

Doesn't use shuf, its much faster with "shuf -n4" instead of sort -R

RANGE=`wc -l /usr/share/dict/words | sed 's/^\([0-9]*\) .*$/\1/'`; for i in {1..4}; do let "N = $RANDOM % $RANGE"; sed -n -e "${N}p" /usr/share/dict/words | tr -d '\n'; done; RANGE=100; let "N = $RANDOM % $RANGE"; echo $N
jot 4 | awk '{ print "wc -l /usr/share/dict/words | awk '"'"'{ print \"echo $[ $RANDOM * $RANDOM % \" $1 \"]\" }'"'"' | bash | awk '"'"'{ print \"sed -n \" $1 \"p /usr/share/dict/words\" }'"'"' | bash" }' | bash | tr -d '\n' | sed 's/$/\n/'

So I use OSX and don't have the shuf command. This is what I could come up with.

This command assumes /usr/share/dict/words does not surpass 137,817,948 lines and line selection is NOT uniformly random.

cat /usr/share/dict/words | grep -P ^[a-z].* | grep -v "'s$" | grep -Pv ^.\{1,15\}$ | shuf -n4 | tr '\n' ' ' | sed 's/$/\n/'

The first grep rejects capitalised words since the dict has proper nouns in it that you mightn't want to use. The second grep rejects words with ending in apostrophe s, and the third forces the words to be at least 15 characters long.

shuf -n4 /usr/share/dict/words | sed -e ':a;N;$!ba;s/\n/ /g;s/'\''//g;s/\b\(.\)/\u\1/g;s/ //g'

This is what I came up to generate XKCD #936 style four-word password.

Since first letter of every word is capitalized it looks a bit more readable to my eyes.

Also strips single quotes.

And yes - regex is a bit of a kludge, but that's the bes i could think of.

To get a random xkcd comic:

xdg-open http://dynamic.xkcd.com/random/comic/
xkcd() { wget -qO- http://xkcd.com/ | sed -n 's#^<img src="\(http://imgs.[^"]\+\)"\s\+title="\(.\+\?\)"\salt.\+$#eog "\1"\necho '"'\2'#p" | bash ; }

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic.

To get a random xkcd comic use the following:

xkcdrandom() { wget -qO- http://dynamic.xkcd.com/comic/random | sed -n 's#^<img src="\(http://imgs.[^"]\+\)"\s\+title="\(.\+\?\)"\salt.\+$#eog "\1"\necho '"'\2'#p" | bash; }

These are just a bit shorter than the ones eigthmillion wrote, however his version didn't work as expected on my laptop for some reason (I got the title-tag first), so these build a command which is executed by bash.

eog `curl 'http://xkcd.com/' | awk -F "ng): |</h" '/embedding/{print $2}'`
gwenview `wget -O - http://xkcd.com/ | grep 'png' | grep '<img src="http://imgs.xkcd.com/comics/' | sed s/title=\".*//g | sed 's/.png\"/.png/g' | sed 's/<img src=\"//g'`

Output the html from xkcd's index.html, filter out the html tags, and then view it in gwenview.

Will create a graph of the results for "x bottles of beer on the wall".

Requires Gnuplot.
