Difference between using Here document and Expect in scripts
Hi,
I am confused between using here document and using expect for writing interactive shell scripts(like changing password ,FTP or doing su).
My questions are :
1)Why here documents cant change password from shell script.
2)Why we need to use expect for same?
3) Can Sourcing a script can do FTP or change password? like
or
4) What is the difference in all three behaviors(here,expect and source)?
Tried to resolve these on own but still i am confused.

lchage
lchage(1) General Commands Manual lchage(1)NAME
lchage - Display or change user password policy
SYNOPSIS
lchage [OPTION]... user
DESCRIPTION
Displays or allows changing password policy of user.
OPTIONS -d, --date=days
Set the date of last password change to days after Jan 1 1970.
Set days to -1 to disable password expiration (i.e. to ignore --mindays, and --maxdays and related settings).
Set days to 0 to enforce password change on next login. (This also disables password expiration until the password is changed.)
-E, --expire=days
Set the account expiration date to days after Jan 1 1970. Set days to -1 to disable account expiration.
-i, --interactive
Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.
-I, --inactive=days
Disable the account after days after password expires (after the user is required to change the password). Set days to -1 to keep
the account enabled indefinitely after password expiration.
-l, --list
Only list current user's policy and make no changes.
-m, --mindays=days
Require at least days days between password changes. Set days to 0 or -1 to disable this requirement.
If this value is larger than the value set by --maxdays, the user cannot change the pasword.
-M, --maxdays=days
Require changing the password after days since last password change. Set days to -1 to disable password expiration.
-W, --warndays=days
Start warning the user days before password expires (before the user is required to change the password). Set days to 0 or -1 to
disable the warning.
EXIT STATUS
The exit status is 0 on success, nonzero on error.
NOTES
Note that "account expiration" (set by --expire) is distinct from "password expiration" (set by --maxdays). Account expiration happens on
a fixed date regardless of password changes. Password expiration is relative to the date of last password change.
