shell script clarification
HI,
I wrote the below script to find the files by geeting the input from the user like below
Code:
echo 'FINDING THE FILES IN THE CURRENT PATH'
read a
c=$a
echo 'THE FILE NAME IS' $c 'PLEASE COMFIRM with Y OR N'
read b
d=$b
echo $d
if [ $d =  'Y' ]
then
  echo `find . -name` $c
elif [ $d =  'N' ]
then
  echo 'TRY WITH NEW SEARCH'
else
  echo 'NO'
fi

I compiled the same but it it's not executing properly while am giving y also its quits and came out of the loop.

the output looks like this
Code:
FINDING THE FILES IN THE CURRENT PATH
thelak
THE FILE NAME IS thelak PLEASE COMFIRM with Y OR N
y
y
NO

Please help!

Thanks
Thelak Kumar

Code:
#!/bin/bash
read -p "FINDING THE FILES IN THE CURRENT PATH : " a
read -p "THE FILE NAME IS' $a 'PLEASE COMFIRM with Y OR N : " b
if [ "$b" = "Y" ]
then
	find . -name "$a"
elif [ "$b" = "N" ]
then
	echo 'TRY WITH NEW SEARCH'
else
	echo 'NO'
fi

I'm using bash, which shell are you using?

Code:
leo@leo-desktop:~/Escritorio$ bash shell.sh 
FINDING THE FILES IN THE CURRENT PATH : camel.ico
THE FILE NAME IS' camel.ico 'PLEASE COMFIRM with Y OR N : Y
./raes/camel.ico
leo@leo-desktop:~/Escritorio$

(In "ksh" "read -p" tries to read from a pipe. The error message looks like ksh on AIX).

Here is your script modified to introduce the loop you require while retaining all your original logic. I have also corrected the syntax of the "find" command and both "if" statements.
The loop is a do-done loop using the "break" command to exit.

Code:
while true
do   echo 'FINDING THE FILES IN THE CURRENT PATH'
   read a
   c=$a
   echo 'THE FILE NAME IS' $c 'PLEASE COMFIRM with Y OR N'
   read b
   d=$b
   echo $d
   if [ "$d" =  'Y' ]
   then
     find . -name $c -print
   elif [ "$d" =  'N' ]
   then
     echo 'TRY WITH NEW SEARCH'
   else
     echo 'NO'
     break
   fi
done

Consider that `Y' is not the same as `y'

If you want to allow both "Y" and "y", try a case statement:

Code:
while true
do
   echo 'FINDING THE FILES IN THE CURRENT PATH'
   echo 'ENTER FILENAME'
   read a
   c="$a"
   echo "THE FILE NAME IS $c PLEASE CONFIRM with Y OR N"
   read b
   d="$b"
   #echo $d
   case "$d" in
         y|Y)
            find . -type f -name "$c" -print
            ;;
         n|N)
            echo 'TRY WITH NEW SEARCH'
            ;;
         *)
            # Answer was not Y/y/N/n
            echo 'EXITING'
            break
            ;;
   esac
done
