[SLE] Files modified while copying from USB-card
Hello all! I have this script that copies all files from my digital camera into a new folder upon execution. But now and again (Not always) i get an error like: cp: skipping file `/media/usbdisk/dcim/100pentx/imgp0099.jpg', as it was replaced while being copied The card is automounted and not touched while the script is ran. So why is the filesystem on the card touched and (apparently) changed?

The card is automounted and not touched while the script is ran. So why is the filesystem on the card touched and (apparently) changed? That error message, as cryptic as it is, seems more like what you'd get if the file already exists in the destination, and cp was run without

I doesn't. The destination is freshly made at each pass by the script. It creates a folder 'yymmdd.xx' where 'xx' is an incremented sequential number. So if i run the script twice the same date, it still differs by the last two digits (01,02 etc). So it CAN'T find anything in the target. (Or at least shouldn't) The script is as follows for those who want to debug: maybe not very intelligent or pretty regarding code, but it runs :) (Bits and pieces from helpful ppl here on the list...) -- cut -- #!/usr/bin/perl use strict; use warnings; use File::Path; my $dst_dir = "/mnt/network/dual/hdc/Pictures"; my $src_dir; for(1..10){ { open my $in,"/proc/mounts" or die "$!\n"; $/=undef; ($src_dir) = <$in>=~/ (\S*usbdisk\S*)/; close $in; } last if defined $src_dir; sleep 2; } die "Could not calculate \$src_dir" unless defined $src_dir; my @time = localtime(time); my( $year ) = $time[5]=~/(\d\d)$/; my $month = $time[4]+1; $month="0$month" if $month<10; my $day = $time[3]; $day="0$day" if $day<10; $dst_dir.="/$year/$month/$year$month$day"; my $xx="01"; while( -d "$dst_dir.$xx" ){ $xx++; } $dst_dir.=".$xx"; mkdir $dst_dir or die "$!\n"; mkpath($dst_dir); `cp -r $src_dir/dcim/100pentx/* $dst_dir/`; -- uncut -- -- /Rikard ----------------------------------------------------------------------------- email : rikard.j@rikjoh.com web : http://www.rikjoh.com mob: : +46 (0)763 19 76 25 ------------------------ Public PGP fingerprint ---------------------------- < 15 28 DF 78 67 98 B2 16 1F D3 FD C5 59 D4 B6 78 46 1C EE 56 >

---- Script and some text removed... The odd and bit scary thing is i tried writeprotecting the SD-card and still get the error from time to time... The mount point /media/usbdisk/ is per automation, and the dcim/100pentx is the folder tree made by tha digital camera. How can a file on a writeprotected filesystem get changed just by a pla8in copy ??? -- /Rikard ----------------------------------------------------------------------------- email : rikard.j@rikjoh.com web : http://www.rikjoh.com mob: : +46 (0)763 19 76 25 ------------------------ Public PGP fingerprint ---------------------------- < 15 28 DF 78 67 98 B2 16 1F D3 FD C5 59 D4 B6 78 46 1C EE 56 >
