Run Commands without Spaces [closed]

Question

I won't bore you with the details but I need to pass a command to a file without spaces, with each space it considers the next text to be a variable which is not the case. I need to be able to create a command with another character other than space or use hex characters to overcome this. Unfortunately I am completely locked to using this method as this file exists on 1000s of devices and I would need to change the file manually on each device, if I can workaround it's limitations then this would be the best solution for me.

Does anyone have any ideas if this is possible?

edit Hi guys for some more info, lets say I have the file test.sh, it has a function called echo_var, if I use the command for example

test.sh echo_var helloworld

The function will simply echo helloworld

If I say use the command

test.sh echo_var hello world

Only hello gets echoed as it considers "hello world" as two strings and only acknowledges the first one, the function takes each separated string as a variable and only uses the first variable ie hello. I need to make hello world one variable

The command I want to run is to restart a service ie

test.sh echo_var hello&&service apache2 restart

So both hello will be echoed and the service restarted. But after the space after service, the command is cut.

Here is the file (test.sh) I have to interact with, again this is on 1000s of devices and I need to work with it:

case "$1" in
    echo_var)
        echo "$2"
        ;;

Answer 1

Use double quote around your string

Below one should work fine

test.sh echo_var "hello world"

Answer 2

#!/bin/sh
echo_var="hello world"
echo  $echo_var

Are you looking for something like this?

#!/bin/sh
echo_var="Apache Server Restarted"
echo  $echo_var >> /var/log/ApacheRestart.log
service apache2 restart

So something like this might help you out.

Answer 3

The solution for me was the following:

./test.sh echo_var test1;what="service restart apache2";$what

This means the spaces are never caught by the script
