Anyone can help me?

How to manage a simple database (text file)
How to manage a simple database (text file)
I'm trying to do a simple database with this schema using text file:
How to use data is simple and how to search or insert a new line is easy.
But I don't know how to do things like modify an entry (or delete but I don't need delete for my script).
Anyone can help me?

Re: How to manage a simple database (text file)
Just thinking about it ( I haven't experimented and tried it) ... could you read your text file into a list?
( http://forum.egghelp.org/viewtopic.php?t=6885 )
Then, manipulate the list... searching, replacing, etc.
( ex: http://www.tcl.tk/man/tcl8.5/TclCmd/lreplace.htm
and
http://www.tcl.tk/man/tcl8.5/TclCmd/lsearch.htm )
When done, write the list back to text file, overwriting the original file.
Is that viable?
p.s. There is a high probability that I've read about doing it this way, somewhere in the past. Most likely, that would be this forum. In other words, it might be a good idea to try some searches here... you might find it described in more detail.
