simple shell script problem

solution:recursively calling a function
hiiii djt0506,
got a easy solution for you
...
you neeed to write a function "function Func_validate_phone_number" which will validate the phone number entered by the user.
if the ph no is blank it will again call the same function and will ask the user to enter it again....until he enters any thing other than "enter".
if you want to validate it further (for valid numbers or no characters etc) then you need to do some more validations....which again quiet easy
.
here is my code....
function Func_validate_phone_number {
if [ -z "$ph" ]
then
echo "Phone Number cannot be blank....please re-enter."
read ph
Func_validate_phone_number "$ph"
else
echo "Thanks for giving your phone number.....bye"
fi
}
echo "Enter the phone number"
read ph
Func_validate_phone_number "$ph"
i have tested it .....it works fine
...

This is a search script that I have developed. It finds the records that I look for. However the only thing I want the program to do now is to display a message such as 'Not Found' to appear when a record is not found. So far when a search doesn't display a record, the screen is blank.

phones(4) File Formats phones(4) NAME
phones - remote host phone number database SYNOPSIS
/etc/phones DESCRIPTION
The file /etc/phones contains the system-wide private phone numbers for the tip(1) program. /etc/phones is normally unreadable, and so may contain privileged information. The format of /etc/phones is a series of lines of the form: <system-name>[ ]*<phone-number>. The system name is one of those defined in the remote(4) file and the phone number is constructed from [0123456789-=*%]. The `=' and `*' characters are indicators to the auto call units to pause and wait for a second dial tone (when going through an exchange). The `=' is required by the DF02-AC and the `*' is required by the BIZCOMP 1030. Comment lines are lines containing a `#' sign in the first column of the line. Only one phone number per line is permitted. However, if more than one line in the file contains the same system name tip(1) will attempt to dial each one in turn, until it establishes a connection.
