Bash array outputs numbers instead of strings

Question

I'm trying to split a line with multiple ' in it, but the result are numbers, not strings, trying to get the 1st occurrence of ', I mean the string YouTube down there:

line="application: label='YouTube' icon='res/uFR.xml'"
echo $line
IFS="'"
read -a stringArray <<< "$line"
echo "${stringArray[1]}"

Current Output:

112

Expected Output:

YouTube

I can't tell if it's the problem here, but setting IFS globally like this can cause all sorts of weird problems, especially when you're also using word splitting (which depends on IFS) to get the items the for loop iterates over (which also isn't very safe on its own, either). It's better to make it a prefix of the read command (IFS=\' read -a ...) so that it only applies to that one command. — Gordon Davisson

the latest edit (line=.. / echo $line / IFS=... / read -a ... / echo ...) works for me and generates as output the string YouTube; and the array contents look correct: typeset -p stringArray => declare -a stringArray=([0]="application: label=" [1]="YouTube" [2]=" icon=" [3]="res/uFR.xml") — markp-fuso

please update the question what a textual snippet of the code that shows up in the imgur image, making sure to specify that you're running this script under adb — markp-fuso

Can you believe this guys ?! It should be capital A, not small a, must be Bash magic :)

read -A stringArray <<< "$line"

I'd like to note here that Linux files must've combatible line ending to be read correctly: Notepad++ -> Edit -> EOL Conversion -> Unix (LF), or you can just Console.Write("string" + "\n");

i think the IFS variable should use quotes for it to be literal, if this does not work then to also escape the quote character with IFS='\''

Thanks, but this is not the case, it works fine in Ubuntu like the screenshot in the main post says.
