Extract file contents into array using Bash
arrays, bash
Solution
You can use a loop to read each line of your file and put it into the array
# Read the file in parameter and fill the array named "array"
getArray() {
array=() # Create array
while IFS= read -r line # Read a line
do
array+=("$line") # Append line to the array
done < "$1"
}
getArray "file.txt"
How to use your array :
# Print the file (print each element of the array)
getArray "file.txt"
for e in "${array[@]}"
do
echo "$e"
done

How to extract a file content into array in Bash line by line. Each line is set to an element. I've tried this: ``` declare -a array=(`cat "file name"`) ``` but it didn't work, it extracts the whole lines into `[0]` index element
