Write a shell program to cipher all the text/content in any text document in the current working directory and also use another shell program to decipher it to read. Use any scheme for ciphering.
This looks like a homework question. Members of this forum will not do your homework for you. Members will help but you must first show the code you have and ask a specific question.
Check out Mendel Cooper's Advanced Shell Scripting Guide: http://tldp.org/LDP/abs/abs-guide.pdf
