For the lines that are printing errors to the monitor, put in
2>/dev/null at the end of the line.
Basically this directs error messages to the universal garbage bin
(/dev/null) while putting other messages out to the screen.
You can test that a command has executed correctly by looking at
the value of $?. If there were no errors then it returns 0.
You could use this to determine whether to print the messages
Files Found! etc. etc.
If I understand you correctly you could do something like:-
ls/home/user/workflow/Proofers/A4/*.pdf 2>/dev/null
if [ $? -eq 0 ] ; then
echo "Files Found!!"
lp -d brothers /home/user/workflow/Proofers/A4/*.pdf 2>/dev/null
if [ $? -eq 0 ] ; then
echo "Files Printed!!"
