SOLVED import output from one script to another script?

#1 Post by GDixon »

Help

i'm getting most of what i need and learning case esac , it's not so bad

if then fi else elif is a cake walk now and nesting is an exercise in indenting and knowing what you need before hand.

grep isn't too bad but awk is killing me

how can I get the out put of something like this into a second script?

Code: Select all

MAIN_TARGET=$(tac $PLACES | grep -m 1 "$SCAN_TARGET_1" | awk '{print $NF}')
I found separating the menu portion from the main scan script (avscan of clam) allows me to get the menu working correctly. If i embed the menu in the scan script funny things happen when you enter a wrong choice.
separating major functions to their own scripts makes thing a lot easier for me to edit and maintain also .

i kinda stripped most things from the scripts to get them running with a minimum of crud for testing.

this is the text file i store the scan targets in | SCAN_TARGET_1 through _5 that grep finds it's info .

Code: Select all

/media/Storage/NewQbToTransfer/

/media/Storage/

/media/Extra/

/media/TvShows/
this is the case menu script that I need the MAIN_TARGET info from for the scan script.
Ignore most the variables I need to clean them up still.

Code: Select all

#!/bin/bash

clear

# Remember to make executable and check permissions

# case menu for avscan

lots of clean up left but it will run , problem is without the MAIN_TARGET getting imported avscan falls back to scanning the home directory.

what am I missing and just haven't got my mind wrapped around yet?
Any suggestions or a direction to try?

I think I found a direction

Make the variable an environment variable (export TESTVARIABLE) before executing the 2nd script.

I'm going to give this a try and see what happens.

I'm still open to suggestions and or other directions I can take in doing this.

When you don't want to use external files, and piping doesn't offer a fine enough control, "process substitution" can be useful. It is particularly good when you need to examine the output of a command (or script) line by line within a while/read/do/done loop.

This may be more than you need. But when you do have a situation where it can be used, it can save all sorts of convoluted work-arounds.

Note the warning about "no space between the '<' and the parentheses".

Re: how do I import output from one script to another script

export as a system variable was the answer and it allowed me to clean a lot of crud out of the scripts.
I imagine I could put all my variables in the menu script and export them all as system variables but the seems counter to having them in the scripts they belong in.

This is my first menu using case over if then else and it seems cleaner and easir but not by a lot, not sure I will prefer one way over the other in time.

heres a sample of the code for the menu to export what I needed which also got rid of a lot of convoluted crud, super simple once you find out how.

Code: Select all

1 ) clear; echo
            echo -e "$INFO_1 $SCAN_TARGET_1 $USER\n"           
            sleep 3; clear
            export MAIN_TARGET=$SCAN_TARGET_1; $SCAN ;;
