Shell Programming and Scripting

hi guys

Kindly see the below script

#!/bin/bash

if [ -d /root/joy/ ]
then
# check to see if file notrouter exits or not
if ! ls -l notrouter /root/joy/ >/dev/null
then
touch /root/joy/notrouter
else
echo "Entries already exist"
fi
else
echo "Entries does not exist"
fi

here the problem is that when i run the script it runs but shows me(see below)
# ./comb3
ls: notrouter: No such file or directory
and when i do ls -l notrouter(filename) the file is created
Is their any way were the script runs successfully without prompting the above syntax
Or is their any different method in order to accomplish the task
Thnks in advance!
reg:ash

check "man test"

Inorder to check the availability of a file use " -f option "

In your case

if [ -f /root/joy/notrouter ]
then
echo "Entries already exist"
else
touch /root/joy/notrouter
fi
