IF I understood correctly the end of your requirement: you need it display AND copying output in a file then you will have to look at the command tee...
The best for you to figure out what it to be done is write in pseudocode how the script should work, submitting here we would help and correct to get you doing what you are asked but dont expect we give you the solution ( even if we are tempted.. haha Its hard for us to not and figure out what/what not to post...)
Your script should be divided in 2 paragraphs:
Code:
# Initialize your variableis:
MYPWD=""
PASS="lux"
PASSCPT=0
.
# Testing condition:
While ..
# 2 possibilities: while passwd is not good OR $PASSCPT -lt 3
# I let you decide... one of course is more legeant than the other...
# Remember that if codition is met to get out by some means
# e.g using break in a if condition...
..
done
#Post testing treatment # You should enter here only if required condition are met!
ls- l
.
#Ask username...
# write at end of generated file
End
Waiting to see your new submission!
Courage!
