shell script executes program, but waits for a prompt
Sorry, newbie here. I have the following shell script which basically executes the sh-n-body.i686 program a specified number of times. However, before the sh-n-body.i686 begins its calculations it prompts for input from the user. In this case the user would have press ". return" and sh-n-body.i686 will continue running. However, I just want the code to run about 100 times without having to enter . return. How can I modify the shell script so that it takes care of the prompt( . return).
#!/bin/sh
COUNTER=0
while [ $COUNTER -lt 100 ]; do
./sh-n-body.i686 56 3 32 0.02 1 -2 | grep "longest shadow"
let COUNTER=COUNTER+1
done
Thank you

smfi_replacebody(3N) smfi_replacebody(3N)
NAME
smfi_replacebody() - replaces the data in the sendmail message body
SYNOPSIS
PARAMETERS
ctx Specifies the opaque context structure.
bodyp Specifies a pointer to the start of the new body data, which does not have to be null-terminated. If bodyp is set to NULL, the
length of the body is considered to be 0 (zero). The body data must be in CR or LF form.
bodylen Specifies the number of data bytes pointed by bodyp.
DESCRIPTION
replaces the body of the current message. can be called only from the routine and can be called more than once. When is called more than
once, the subsequent calls append data to the new body of the message.
Notes
o As the message body may be very large, setting may significantly affect filter performance.
o If a filter sets but does not call the original body remains unchanged.
o The filter order is important for the routine. Filters placed later in the sequence will observe the changes
RETURN VALUE
fails and returns due to the following reasons:
o The value of bodyp is equal to NULL and the value of bodylen is greater than 0.
o Changing the body in the current connection state is invalid.
o Network error occurs.
o The is not set when the function is called.
