For the BTP we needed a way to wipe data for returning broken comps to the manufacturer. After a search on Google I found wipe.sourceforge.net; but that seemed old and buggy. Then I found some tools in a suite called secure-delete. It’s in the default debian repo’s

So on Debian/Ubuntu:

A quick howto:

packacge secure-delete has four tools:

srm - securely delete an existing file smem - securely delete traces of a file from ram sfill - wipe all the space marked as empty on your hard drive sswap - wipe all the data from you swap space.

From the man page of srm
