Sorry if the title is not good but I did not know how to explain with only some words!
What I meant is: I have a unix command built from a private application vendor that when executed it prompts for two entries by the keyboard, let's say, for example:
Code:
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Enter your:
UserName: <Keyboard Enter UserName> <Press EnteR>
EMail : <Keyboard Enter EMail> <Press EnteR>
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
After inputting the information above using the keyboard and pressing <EnteR>, it shows an output like below:
Code:
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
ENCRIPTING THE PASSWORD.....
ENCRIPTED PASSWORD : XXXXXXXXXXXXXXX
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Finally, my question is:
Is there a way to put the command above inside a shell script?
The user must enter the two fields and after I need to get the "Encripted Password".
I'm trying to write a simple script program (C shell). I have a problem redirecting input into a variable. Say I have a variable called J, and there is file called result which contains just some number, say 5. Which command should I use to assign J value 5 from the file result. I tried the... (2 Replies)
I need to run a command inside root-environment, and want to use:
su - root -c "some command..."
Then I am prompted for a password, of course.
Is it possible to put this password in a file, and present this files content, to the command above?:confused: (1 Reply)

Any suggestions?

source
exec(1) User Commands exec(1)NAME
exec, eval, source - shell built-in functions to execute other commands
SYNOPSIS
sh
exec [argument...]
eval [argument...]
csh
exec command
eval argument...
source [-h] name
ksh
*exec [arg...]
*eval [arg...]
DESCRIPTION
sh
The exec command specified by the arguments is executed in place of this shell without creating a new process. Input/output arguments may
appear and, if no other arguments are given, cause the shell input/output to be modified.
The arguments to the eval built-in are read as input to the shell and the resulting command(s) executed.
csh
exec executes command in place of the current shell, which terminates.
eval reads its arguments as input to the shell and executes the resulting command(s). This is usually used to execute commands generated as
the result of command or variable substitution.
source reads commands from name. source commands may be nested, but if they are nested too deeply the shell may run out of file descrip-
tors. An error in a sourced file at any level terminates all nested source commands.
-h Place commands from the file name on the history list without executing them.
ksh
With the exec built-in, if arg is given, the command specified by the arguments is executed in place of this shell without creating a new
process. Input/output arguments may appear and affect the current process. If no arguments are given the effect of this command is to mod-
ify file descriptors as prescribed by the input/output redirection list. In this case, any file descriptor numbers greater than 2 that are
opened with this mechanism are closed when invoking another program.
The arguments to eval are read as input to the shell and the resulting command(s) executed.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
EXIT STATUS
For ksh:
If command is not found, the exit status is 127. If command is found, but is not an executable utility, the exit status is 126. If a redi-
rection error occurs, the shell exits with a value in the range 1-125. Otherwise, exec returns a zero exit status.
