problem incorrectly cited by you. Still, your entire code wouldn't work as
- you don't create an array
- even if you created an array by using the a=(...) syntax, it would contain 27 elements to loop across with for.
- even if you had a 3 element array, the ${a[@]} expansion wouldn't supply those three.


Code:
IFS="'" read -a a <<< $FPATH

would create the desired three element array, and e.g. IFS=$'\n'; echo "${a[*]}" would correctly expand it.


Or try
Code:
while read LN; do echo $LN; done <<< $(echo "$FPATH" | tr \' $'\n')

@RudiC Thank you for the help though it still does not work. Below is the complete snippet.

Code:
#!/bin/bash
input="../vars/hello.txt"
while IFS= read -r line
do
    echo "$line"
    IFS=': ' read -r ip string <<< "$line"
    FPATH="$string"
    FPATH=${FPATH//$'u\''/}
    echo "PRINTING4:$FPATH"
    printf  "\n" >> new_test.txt

    while read LN; 
    do
        echo $LN; >> new_test.txt
     #done <<< $(echo "$FPATH" | tr \' $'\n')
     done <<< $(echo "$FPATH" | tr "'" "\n" | sed "s/^ //g")
done < "$input"

I get blank i.e no entries in the new_text.txt instead of the desired output. even when i try the other suggestion i.e done <<< $(echo "$FPATH" | tr \' $'\n')

Debug shows:
Code:
PRINTING4:-rw-rw-r-- 1 user1 dba 0 Aug  7 13:14 /app/F11.3/app/cust/exe/filename1.exe'  -rw-rw-r-- 1 user1 dba 0 Aug 19 10:09 /app/app/F11.3/app/cust/sql/33211.sql'  -rw-r--r-- 1 user1 dba 0 Aug  6 17:20 /app/F11.2/app/01/mrt/file1.mrt'
