Games Magazine - Combos

From Kyle's Wiki
Jump to: navigation, search

Combos is a Games Magazine puzzle where one must find Disney animated films that have a series of letters in the title. An example is "erpa = Peter Pan" because the letters e,r,p,a appear in Peter Pan in that order. Sounds like a perfect job for Grep!

Code

Here is the code:

#!/bin/bash
for LETTER in `echo $1 | sed 's/./&\n/g'`
do
COMMAND="$COMMAND ?$LETTER"
done
exec egrep -e "$COMMAND" list

Explaination

The code outputs an grep command like this:

grep -e ' ?n ?d ?w' list

The class " ?" matches a possible blank space, then we have a "n", then any number of characters, and so on. The above shell script just makes it easy to create those reg-ex's.
