1. The problem statement, all variables and given/known data:
I need help I get a variant of syntax errors when compiling my script to maintain a database. It's a simple database meant to create/view/maintain vehicles.
2. Relevant commands, code, scripts, algorithms:
my if statements have many syntax errors and I'm lost as to why. One key lines is line 8 my first if statement. Thanks in advance.
3. The attempts at a solution (include all code and scripts):
Code:
#! /bin/bash
# Automobile database
db=arg1
command=arg2
case $db in
#create:
if [ -f "$db" ]; then
echo "DATABASE EXSISTS"
if [ $arg3 != "" ]
echo $arg3 > db
else
echo "Automobile Database" > db
echo "New database created"
fi
esac
#add
read -p "Make of the car: " make
read -p "Model of the car: " model
read -p "Year of the car: " year
read -p "Color of the car: " color
if $year < 1870 || $year > 2020
echo "Error with $year"
fi
echo "$make, $model, $year, $color" >> db
echo "Successfully added a record to the database"
case $arg3:
max=$( wc -l db )
#all:
cat db
if $arg4 > $max
echo "Error"
fi
sed -ne "1p;arg4p" db
#range:
if $arg4 > $max || $arg5 > $max || $arg4 > $arg5
error
fi
sed -ne "1p;arg4,arg5p" $db
esac
#delete:
case $arg3:
max=$( wc -l db )
sed -ie '2,$d' db
single:
if $arg4 > $max
echo "error"
fi
sed -ie "$arg4d" db
range:
if $arg4 > $max || $arg5 > $max || $arg4 > $arg5
echo "Error"
fi
sed -ie "arg4,arg5d" db
esac

kdb_init
kdb_init(8krb)kdb_init(8krb)Name
kdb_init - initialize the Kerberos master database
Syntax
/var/dss/kerberos/bin/kdb_init [ realm-name ] [ database-name ]
Arguments
realm-name The realm of the Kerberos database.
database-name
A database specified so that the current and files are not overwritten.
Description
The utility creates and initializes the Kerberos master database. The utility creates the database files: and It also initializes the
database by adding three database entries: the master database principal, a Kerberos default principal, the ticket-granting service princi-
pal ( and the password changing principal,
The master database principal is the entry to the database itself. You cannot use or modify the database without the master database pass-
word. The Kerberos default principal provides a template for service principals.
The ticket-granting service, is used by Kerberos principals to obtain tickets to communicate with other Kerberos principals. The password-
changing principal is not used.
If realm-name is omitted when you enter the command, prompts for it. The program also prompts for the master database key. You cannot
manipulate the database without this key.
By using database-name, you can create another database to prevent the current and files from being overwritten.
After using to set up the master database, you may want to use the utility to hide the master database password on the database host
machine. This enables Kerberos administration programs to access and manipulate the master database, without needing the password to be
entered manually.
