Delete Record into a Sequential File ( Disc Spaces ??)

[royinfo]

Hello,

I'm doing right now a massive Records deletion into sequential Files. (With Rm cocol Programs)

If I'm looking the size of the file Before and After it's the same .. Why

With Unix is it possible to use a command like TAR or Backup/Restore to recreate the file to have my space available ?

thanks

You are marking individual records as deleted in the index. The record space remains untouched, the index is modified.
If you know enough to search through the file to delete you should be able to search through and copy active records to another file. Then remove the old file and extract back from the backup.

I've not worked with the database programs except for rebuilding the files and indexes when things corrupt.
