grab all commandlinefu shell functions into a single file, suitable for sourcing.

export QQ=$(mktemp -d);(cd $QQ; curl -s -O[0-2400:25];for i in $(perl -ne 'print "$1\n" if( /^(\w+\(\))/ )' *|sort -u);do grep -h -m1 -B1 $i *; done)|grep -v '^--' >;rm -r $QQ
Each shell function has its own summary line, as a comment. If there are multiple shell functions with the same name, the function with the highest number of votes is put into the file. Note: added 'grep -v' to the end of the pipeline, to eliminate extraneous lines containing only '--'. Thanks to matthewbauer for pointing this out.

What Others Think

Nice idea but it has all these "--" lines. If you delete those everything seems to be ok.

When I wrote the command, I didn't re-direct to a file... didn't notice the '--' lines. Tried to add a grep -v to remove them, but pushed the command over 255 characters, so I'll have to golf it a little....

I've golfed the command and fixed the '--' problem... trouble is that I'm still getting several shell functions with the same name. The problem is that while 'grep -m1' should only include the first match on a given pattern, it seems that it's including the first match *per file*... I'll have to give this some thought. Also, as an aside: there are a number of shell functions which have syntax errors... by far the most common is omitting the final ';' before the closing brace.

I have a lot of commandlinefu because I've learning them, this is a great idea to try. ProTurf Artificial Grass Solution
