Estimate readability of text using the Dale Chall formula.
To compute the readability score of a text file named story.txt
, you would run
this command in the directory where both readability
and story.txt
reside.
./readability story.txt
If the readability
binary and story.txt
were in different locations, you
might use something like this instead:
readability ~/Documents/story.txt
./readability testdata/modelt4
READABILITY OF "testdata/modelt4"
