Top Forums UNIX for Advanced & Expert Users Special copy across filesystems during download Post 302382154 by jim mcnamara on Tuesday 22nd of December 2009 10:48:30 AM

Yes. But you are absolutely not guaranteed to have copied the entire file when the cp command ends for the disk -> pen drive.

Why - if the USB port moves data faster than the other process "downloading" the file can move data, then the USB can enounter a premature end of file by reading faster than the data ftp stream is being written and hitting the end of the file (from it's perspective) while the other process is still writing.

update-smart-drivedb [OPTIONS] [DESTFILE] DESCRIPTION
[This man page is generated for the Linux version of smartmontools. It does not contain info specific to other platforms.] update-smart-drivedb updates /var/lib/smartmontools/drivedb/drivedb.h or DESTFILE from smartmontools SVN repository. It tries to download first from the current branch and then from trunk. The tools used for downloading are either curl(1), wget(1), lynx(1), or svn(1). The old file is kept if the downloaded file is identical (ignoring the differences in Id string) otherwise it is moved to drivedb.h.old. OPTIONS
-s SMARTCTL Use the smartctl(8) executable at path SMARTCTL for drive database syntax check. The form '-s -' disables the syntax check. The default is /usr/sbin/smartctl. -t TOOL Use TOOL for download. TOOL is one of: curl wget lynx svn. The default is the first one found in PATH. -u LOCATION Use URL of LOCATION for download. LOCATION is one of: sf (Sourceforge code browser via HTTPS), svn (SVN repository via HTTPS), svni (SVN repository via HTTP), trac (Trac code browser via HTTPS). The default is svn. --cacert FILE Use CA certificates from FILE to verify the peer. --capath DIR Use CA certificate files from DIR to verify the peer. --insecure Don't abort download if certificate verification fails. This option is also required if a HTTP URL is selected with '-u' option. --dryrun Print download commands only. -v Verbose output. EXAMPLES
# update-smart-drivedb /var/lib/smartmontools/drivedb/drivedb.h updated from branches/RELEASE_6_6_DRIVEDB EXIT STATUS
