You could also try something like:
This does all of the processing using shell built-ins (no need to invoke cut or awk) and will work even if $centnam expands to a string containing multiple adjacent whitespace characters.

Hi All,
I have a vexing issue with leading spaces in file names. Basically, we're moving tons of data from our ancient afp file share to Box.com and Box forbids leading spaces in files or folders. The HFS file system seems to be perfectly fine with this, but almost all other Unix file systems... (1 Reply)

Hi,
At the moment, using Notepad++ to do a search and replace, manually section by section which is real painful. Yeah, so copying each section of the line of text and putting into a file and then search and replace, need at least 3-operations in Notepad++.
Here's hoping I will be able to... (1 Reply)

gpiv_series
GPIV_SERIES(1) General Commands Manual GPIV_SERIES(1)NAME
gpiv_series - Script for (parallel) processing a series of numbered files.
SYNOPSIS
gpiv_series [-a | --arg_n] [-b | --basename FILE] [-e | --ext ext] [-f | --first N] [-l | --last N] [-i | --incr N] [-x|| --prefix] [-h |
--help] [-n | --none] [-p | --print] [--pad] "process -key1 ..."
DESCRIPTION
gpiv_series processes a series of numbered files. If no parameters are defined at the command line, standard parameters will be used that
are defined in the script. Principally, any program or script may be invoked by gpiv_series. "Process" is a string which represents the
name of the program to be executed, including eventually command line options and arguments. The file to be processed, as constructed from
-b c.s., will be appended to the "process" string. If the program has to be feeded with -f "filename", write -f at the end of the string.
When using the parallelised version, mpipython is invoked and the script may be launched with mpirun. The script needs that all input files
are accessible on each node by copying all data or by (NFS) mounting the File System containing the input data on each node.
This program does not use the parameter resources from libgpiv.
Options-a | --arg_n
If the process needs the current number in its argument list instead of prepending/appending it to the FILE, the number will be put
before (-f) filename in the "process" string.
-b | --basename FILE
The FILE has to be given without its extension. FILE represents the file name without its number. It is supposed that the leading or
ending number in the filename is the counter that will be applied by gpiv_series when processing.
-e | --ext EXT
add an extension EXT after the filename (without the leading ".") in "process".
-f | --first N
Defines the counter N of the number at which the analyses starts. Default: 0.
-l | --last N
The last number N that will be processed. Default: 0.
-i | --incr N
Increment number with N. Default: 1. This might be useful, for example, if subsequent numbered images are combined for cross-corre-
lation with the gpiv_img2gpiv tool.
-x | --prefix
Use prefix numbering to file basename.
-h | --help
On-line help.
-n | --none
Suppresses real execution, only prints the process to stdout.
-p | --print
Prints the process to be performed on each file to stdout.
--pad N
Padding a number with N zero's when combining with the filename.

BUGS
The parallelised script has only been tested with the LAM version of mpipython.
