Giving instructions to an executable in UNIX?












2















I'm pretty new at this, so excuse me if this is too easy.
The thing is, I have a bunch of instructions stored in a text file named: 'FTIG_dldStruct.txt' and I want to write them all into an executable named: 'STP'. I wrote this script:



#!/bin/bash
set +H

./STP # This is the executable

for i in {1..586}
do
sed -n -e "$i"p FTIG_dldStruct.txt
done


My program runs the executable, and it asks me for input like this:



STP> # I want the instructions here, but my for loop is not working until I exit the executable.

    While MacOS is based on Unix, this is not the Unix stack-exchange. You might find better results on a UNIX-specific board, unless of course your question is actually about MacOS and Terminal

    Welcome Herber - scripting is totally on topic here as on several other sites. No need to go elsewhere unless you don’t get any good answers in 2 weeks time or so. That being said - no worries you are new. Can you edit and clarify - executable normally means a compiled program and scripts / interpreted programs are bash scripts. Are you saying you need to run a program and then process a file when the program ends?

It appears you want to send some number (586?) lines from FTIG_dldStruct.txt to the ./STP command? If so, assuming ./STP reads from standard input as is typical, that may look like:



head -n 586 FTIG_dldStruct.txt | ./STP


If you need ./STP to stick around after those commands are entered so the program can be interacted with, that's a more complicated issue and typically requires something like expect.

  • If you want to send the entire contents of FTIG_dldStruct.txt, it's even easier: ./STP <FTIG_dldStruct.txt.
