Here's an interesting real(ish) world example:
http://www.leancrew.com/all-this/2011/12/more-shell-less-egg/
The goal is to find the ten most common words in a text file.
Donald Knuth wrote something in literate code form, in Pascal. The result
was ten pages of code. In the article, Doug McIlroy wrote it in shell
script as:
1 tr -cs A-Za-z '\n' |2 tr A-Z a-z |3 sort |4 uniq -c |5 sort -rn
|6 sed ${1}q
and called out Knuth on his supposedly more clear, ten-page solution.
It turns out six lines of transcript accomplishes the same thing:
repeat for each word w in replacetext(url ("file:" &
filePath),"(?i)[^a-z]"," ")
add 1 to c[w]
end repeat
combine c using cr and comma
sort lines of c descending numeric by item 2 of each
put line 1 to 10 of c
If anyone can do it more elegantly, I'm curious to know how. But in a
language where we can write our own syntax, this seems likely to be
possible:
put file filePath with all non-alphabetic characters replaced with space
into fileString
for each unique word w in fileString, put w,the count of w & cr after
countList
put the first 10 lines of countList sorted numeric descending by item 2
Maybe that's not clearer, but it should be possible.
