You can be running different shells, like `ksh` or `bash`. Can you tell us your shell (test it with `ps`) ? Maybe we can use https://stackoverflow.com/a/11395181/3220113 – Walter A Oct 29 '18 at 19:36

Yes I am using bash for my shell scripting – Somnath Ghosh Oct 29 '18 at 20:24

Yes, it's possible. Try for yourself, then [edit] your question and post your code as a [mcve]. Tell us what happens when you run it and what you expected to happen instead. – Robert Oct 30 '18 at 02:55

I added a function mv, so you can test this code before you really move things.
Remove the function when your satisfied.
# Test function
mv () {
echo "Command: mv \"$1\" \"$2\""
}
# newnames.txt is a file with lines like sb1 and sb2
readarray -t a < newnames.txt
i=0
# Look for filenames starting with Af
for f in Af*; do
mv "$f" "${a[i]}"
(( i++ ))
# Additional check: Do you have more Af* files than newnames?
(( i == ${#a[@]} )) && { echo "Not enough new filenames"; break; }
done
