Full Discussion: Need to split string on single quote as delimiter

FPATH gets the string by reading it from a file hello.txt.
Code:
input="./hello.txt"
while IFS= read -r line
do
  echo "$line"
IFS=': ' read -r ip string <<< "$line"

Below is how I tried your suggestion.

Code:
a=`echo $FPATH | tr "'" "\n" | sed "s/^ //g"`
   for i in "${a[@]}"
do
   printf '$i' >> output.txt
done

However, due to single quotes printf '$i' we get the output which is enclosed in single quotes.

If I print without single quotes i.e printf $i then the print statement fails becoz of illegal argument like "-r"
Code:
uname -a
Linux mymac 3.10.0-957.12.1.el7.x86_64 #1 SMP Wed Mar 20 11:34:37 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

repodiff

repodiff(1)															       repodiff(1)

NAME

       repodiff - list differences between two or more Yum repositories

SYNOPSIS

       repodiff --old=old_repo_baseurl --new=new_repo_baseurl

DESCRIPTION

       repodiff  is  a	program  which will list differences between two sets of repositories.	Note that by default only source packages are com-
       pared.

GENERAL OPTIONS

       --old, -o
	      Add a repo. as an old repo. Note that if you prefix the url with "mirror:" then the following url is treated as a mirror and  not  a
	      baseurl.

       --new, -n
	      Add  a  repo. as an new repo. Note that if you prefix the url with "mirror:" then the following url is treated as a mirror and not a
	      baseurl.

       --archlist, -a
	      Add architectures to change the default from just comparing source packages.  Note that if you want the same as  a  native  "x86_64"
	      architecture  machine  you  just	need  to  pass	"x86_64"  (this  is  different	from  earlier versions where you needed to specify
	      "x86_64,athlon,i686,i586,i486,i386,noarch" and you still got "src").

       --size, -s
	      Output additional data about the size of the changes.

       --compare-arch
	      Normally packages are just compared based on their name, this flag  makes  the  comparison  also	use  the  arch.  So  foo.i386  and
	      foo.x86_64 are different.

       --simple
	      Output a simple one line message for modified packages.

       --downgrade
	      Split the data for modified packages between upgraded and downgraded packages.

EXAMPLES

       Compare source pkgs in two local repos:
	      repodiff --old=/tmp/repo-old --new=/tmp/repo-new

       Compare x86_64 compat. binary pkgs in two remote repos, and two local one:
	      repodiff -a x86_64 --old=http://example.com/repo1-old --old=/tmp/repo-old --new=http://example.com/repo1-new --new=/tmp/repo-new

       Compare x86_64 compat. binary pkgs, but also compare arch:
	      repodiff	 -a   x86_64   --compare-arch  --old=http://example.com/repo1-old  --old=/tmp/repo-old	--new=http://example.com/repo1-new
	      --new=/tmp/repo-new

       Compare two releases of Fedora (15 => 16):
	      repodiff	  --old='mirror:https://mirrors.fedoraproject.org/metalink?repo=fedora-source-15&arch=i386'	--new='mirror:https://mir-
	      rors.fedoraproject.org/metalink?repo=fedora-source-16&arch=i386' --size --simple --downgrade
