Hi to everyone!!. Here's my stupid question of the day.
When I have to rename a file I use "mv filename newfilename".
But what about renaming multiple files, for example if I want to add the prefix "old" to several image files (in fact it's what I wanted to do..).
Thanks in advance.... :D (6 Replies)

Hi,
Can we rename multiples files using find or awk utility?
Now I am doing it using for loop and getting the file name and in side the loop using the mv command.

FDK(1) Plastimatch FDK(1)NAME
fdk - cone-beam reconstruction from projections using the FDK algorithm
The term FDK refers to the authors Feldkamp, Davis, and Kress who wrote the seminal paper "Practical cone-beam algorithm" in 1984. Their
paper describes a filtered back-projection reconstruction algorithm for cone-beam geometries. The fdk program in plastimatch is an
implmenetation of the FDK algorithm.
FDK USAGE
The fdk program takes a directory of 2D projection images as input, and generates a single 3D volume as output.
The command line usage is:
Usage: fdk [options]
Options:
-A hardware Either "cpu" or "brook" or "cuda" (default=cpu)
-a "num ((num) num)" Use this range of images
-r "r1 r2 r3" Set output resolution (in voxels)
-f filter Either "none" or "ramp" (default=ramp)
-s scale Scale the intensity of the output file
-z "s1 s2 s3" Physical size of the reconstruction (in mm)
-I indir The input directory
-O outfile The output file
-F {F,H} Full or half fan bow-tie filter correction
The usage of the fdk program is best understood by following along with the tutorials: fdk_tutorial_i and fdk_tutorial_ii.
INPUT FILES
Three different formats of input files are supported. These are:
o Pfm format image files with geomtry txt files
o Raw format image files with geomtry txt files
o Varian hnd files
The pfm and raw files are similar, in that they store the image as an array of 4-byte little-endian floats. The only difference is that
the pfm file has a header which stores the image size, and the raw file does not.
Each pfm or raw image file must have a geometry file in the same directory with the .txt extension. For example, if you want to use
image_0000.pfm in a reconstruction, you should supply another file image_0000.txt which contains the geometry. A brief description of the
geometry file format is given in proj_mat_file_format.
The sequence of files should be stored with the pattern:
XXXXYYYY.ZZZ
where XXXX is a prefix, YYYY is a number, and .ZZZ is the extension of a known type (either .hnd, .pfm, or .raw).
For example the following would be a good directory layout for pfm files:
Files/image_00.pfm
Files/image_00.txt
Files/image_01.pfm
Files/image_01.txt
etc...
The Varian hnd files should be stored in the original layout. For example:
Files/ProjectionInfo.xml
Files/Scan0/Proj_0000.hnd
Files/Scan0/Proj_0001.hnd
etc...
No geometry txt files are needed to reconstruct from Varian hnd format.
IMAGE GEOMETRY
By default, when you generate a DRR, the image is oriented as if the virtual x-ray source were a camera. That means that for a right lat-
eral film, the columns of the image go from inf to sup, and the rows go from ant to post. The Varian OBI system produces HND files, which
are oriented differently. For a right lateral film, the columns of the HND images go from ant to post, and the rows go from sup to inf. An
illustration of this idea is shown in the figure below.
