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

dbase_create
DBASE_CREATE(3) 1 DBASE_CREATE(3)dbase_create - Creates a databaseSYNOPSIS
int dbase_create (string $filename, array $fields)
DESCRIPTION dbase_create(3) creates a dBase database with the given definition.
Note
When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script
that is being executed.
Note
This function is affected by open_basedir.
PARAMETERS
o $filename
- The name of the database. It can be a relative or absolute path to the file where dBase will store your data.
o $fields
- An array of arrays, each array describing the format of one field of the database. Each field consists of a name, a character
indicating the field type, and optionally, a length, and a precision.
Note
The fieldnames are limited in length and must not exceed 10 chars.
RETURN VALUES
Returns a database link identifier if the database is successfully created, or FALSE if an error occurred.
EXAMPLES
Example #1

array("date", "D"),
array("name", "C", 50),
array("age", "N", 3, 0),
array("email", "C", 128),
array("ismember", "L")
