Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

line 20 is end of 1st case statement. It's an example I'm trying to work through to understand and run. I have Redhat 8, maybe "OpenLinux" uses different syntax for the shell. Can anyone see offhand what is not liked about this?
The program in full:
# rmv - a safe delete program
# uses a trash directory under your home directory
mkdir $HOME/.trash 2>/dev/null # if dir exists, discard errors
# four internal script vars
# get any command-line options
while getopts "dehl" cmdlnopts; do
case "$cmdlnopts" in
d) /bin/echo "deleting: \c" $2 $3 $4 $5 ; delete=true ;;
e) /bin/echo "emptying the trash..." ; empty=true ;;
h) /bin/echo "safe file delete v1.0"
/bin/echo "rmv -d[elete] -e[mpty] -h[elp] -l[ist] file1-4" ;;
l) /bin/echo "your .trash directory contains:" ; list=true ;;
easc # this is line 20
#d - delete any files found on the command line
if [ $delete = true ]
mv $2 $3 $4 $5 $HOME/.trash
/bin/echo " rmv finished."
#e - empty the trash?
if [ $empty = true ]
/bin/echo "empty the trash? \c"
case "$answer" in
y) rm -fr $HOME/.trash/* ;;
n) /bin/echo "trashcan delete aborted." ;;
# l - show any files in the .trash directory
if [ $list = true ]
ls -l $HOME/.trash
