Creating linux shell scripts

Afternoon all I need 5 linux shell scripts done in bash on centos 6.2 ill send the person that is best for the job these scripts but for now cold you prove you can do them by doing one of the scripts here it is. Script 1 Continuously ask for a file name until the word “stop” is entered. The script will then show, per given file, the number of words in that file, and the percentage of the total number of words of all files together. Eg: [login to view URL] has 305 words which is 9% of all words [login to view URL] has 2458 words which is 74% of all words myEbooks has 580 words which is 17% of all words The script will validate each given file, and act accordingly. Rounding errors can be ignored for the percentages.
