store the echo'ed values into an array in bash script
by linxbee from LinuxQuestions.org on (#5KSS9)
Hi,
I am trying to put some content (only numbers) into a variable using cat command and then using an echo statement trying to put into an array.
But, looks like all the values are stored in 0th index only, instead of storing each element in a different index.
Below is my code and am running it using following command:
Quote:
#My content.txt has following data
Quote:
#shell script for extracting numbers into an array
Code:#!/bin/sh
declare -a list
out=$(cat $1)
list=$(echo "$out" | cut -f1 -d:)
for (( i=0; i<${#list[@]}; i++ )); do
echo ${list[i]};
done
echo $list[0]#I am getting the output as following
