Well, to show it, you can dump the entire database to the shell by 'cat dbfile'.
Your 'add' section is broken. You don't use <= >= in shell, use -le -ge. $$ won't extend the statement, $$ is a special variable meaning the shell's PID.
Also, you forgot the fi.
Also, your if-statement didn't prevent it from doing anything. Put the error stuff in the if section, the success stuff in the else section.
Code:
if [ "$year" -le 1870 ] || [ "$year" -ge 2020 ]
then
...
else
...
fi
And it doesn't add it to the file anyway. echo stuff >> filename to append to the end.
Deleting is not that simple. Lines don't have a 'delete' operation, so deleting it means reading the file out and not printing the lines you want, then replacing the file with the new contents. Were you told any methods like grep for matching and excluding lines from a file?
Code:
# Match only the thing you want
grep "thingtomatch" filename > newfile
# Match everything but the pattern
grep -v "thingtoexclude" filename > newfile

mktemp
mktemp(3C) Standard C Library Functions mktemp(3C)NAME
mktemp - make a unique file name from a template
SYNOPSIS
#include <stdlib.h>
char *mktemp(char *template);
DESCRIPTION
The mktemp() function replaces the contents of the string pointed to by template with a unique file name, and returns template. The string
in template should look like a file name with six trailing 'X's; mktemp() will replace the 'X's with a character string that can be used to
create a unique file name. Only 26 unique file names per thread can be created for each unique template.
RETURN VALUES
The mktemp() function returns the pointer template. If a unique name cannot be created, template points to a null string.
ERRORS
No errors are defined.
EXAMPLES
Example 1: Generate a filename.
The following example replaces the contents of the "template" string with a 10-character filename beginning with the characters "file" and
returns a pointer to the "template" string that contains the new filename.
#include <stdlib.h>
...
char *template = "/tmp/fileXXXXXX";
char *ptr;
ptr = mktemp(template);
USAGE
Between the time a pathname is created and the file opened, it is possible for some other process to create a file with the same name. The
mkstemp(3C) function avoids this problem and is preferred over this function.
