Help how replace stardard keyboard inputs by arguments at run time of a script
Hello Everybody,
Please help.
I was trying to automate the use of a third-party given shell script. The script is written to be used at run-time to collect a few variables to be provided by the user through key board, in the fashion as below:
./runcommand
please provide a file name to dump the output:
then user type in the file name
please provide the user name:
then user type in the user name
please provide password
then user type in the password
please provide role:
then the uese type in the answer to the role
I want to run this command automatically without the user interactive input as I know in advance my answers to those questions.
Ideally like:
./runcommand file_name user_name user_password user_role
or something similar that the command does not wait for the user's interaction.
How can I do that?
Thanks in advance

roles(1) User Commands roles(1)
NAME
roles - print roles granted to a user
SYNOPSIS
roles [ user ...]
DESCRIPTION
The command roles prints on standard output the roles that you or the optionally-specified user have been granted. Roles are special
accounts that correspond to a functional responsibility rather than to an actual person (referred to as a normal user).
Each user may have zero or more roles. Roles have most of the attributes of normal users and are identified like normal users in passwd(4)
and shadow(4). Each role must have an entry in the user_attr(4) file that identifies it as a role. Roles can have their own authorizations
and profiles. See auths(1) and profiles(1).
Roles are not allowed to log into a system as a primary user. Instead, a user must log in as him-- or herself and assume the role. The
actions of a role are attributable to the normal user. When auditing is enabled, the audited events of the role contain the audit ID of the
original user who assumed the role.
A role may not assume itself or any other role. Roles are not hierarchical. However, rights profiles (see prof_attr(4)) are hierarchical
and can be used to achieve the same effect as hierarchical roles.
Roles must have valid passwords and one of the shells that interprets profiles: either pfcsh, pfksh, or pfsh. See pfexec(1).
Role assumption may be performed using su(1M), rlogin(1), or some other service that supports the PAM_RUSER variable. Successful assumption
requires knowledge of the role's password and membership in the role. Role assignments are specified in user_attr(4).
EXAMPLES
Example 1: Sample output
The output of the roles command has the following form:
example% roles tester01 tester02
tester01 : admin
tester02 : secadmin, root
example%
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
