[Perl] script -database
Welcome. I am writing a perl script. I have to design a database consisting of a single table (any subject) saved in a text file. (I make it vi command name and I am giving permission chmod u + x?) The table should contain at least four columns, including a column containing the ID (serial number ) and at least one column of text and numerical data. application written in Perl should allow:
-sort the selected column.
- adding new rows (lines) to the database - with the auto increment Serial Number (ID)
-printing lines with possibility of search in any column (using the regular expression specified by the user), the print order of tuples consistent with the natural order in the file
PLEASE guidance, which in turn have to do. Can someone please bring me a little bit, how do the job
I hope my English is understandable

script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES

attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.11 30 Jan 2004 script(1)
