ext4, ok...try these, although I have not used either, so your mileage may vary. Plus you may want to mount the FS read only ASAP, so that it can prevent any more writes. Basically your recovery chances are maximixed if the underlying inode data structure is preserved and no more changes are allowed.
We have a situation in a large dept of programmers where critical accounting data files were deleted. Is there any way in UNIX to trace deletions and or possibly retrieve the deleted file? (14 Replies)
I had a user run, by accident, the following line command on our UNIX server:
rm -f /usr/*
This apparently deleted some needed files on your system. Having very limited knowledge in UNIX, I thought I would ask the group if anyone knows how I can recover these file?
The version of UNIX is... (3 Replies)
One of the files got deleted and i want to find who deleted that file.
I think we can get the list using history command. Could you please let me know how to get the list of rm commands from history and who previously logged in and did that?
Any other suggestions other than history also... (2 Replies)

Just looking for some guidance on how to figure out who might have deleted some files off one of my systems.
These files are not root owned files so could be deleted by a handful of folks in the group responsible for these files besides the root users.
Anyway I have been tasked with trying to... (1 Reply)

ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
