This question already has an answer here:

Passing arguments from a file to a bash script

3 answers

The command i want to execute:

tool <input> [<input> ...] <output>

I have the input list in a file, separated by newline.

I want to put that file's content into the input field. What I have tried:

First I load the file into an array:

# Load file into array.
declare -a list
let i=0
while IFS=$'n' read -r line_data; do
 list[i]="$line_data"
 ((++i))
done < file.txt

Then I tried using that array in the command as:

tool $list output

But it doesn't work as I expected. Can someone help me on this?

Thank you very much
