Given the simple assumption that a marker should be a smaller value in the first column than in the line previus for creation of a new file the following should do in bash:
sigh: humble & slow
And unreadable. Do all of your scripts looks like that? Is your Enter key broken?
I am trying to cut the first 10 characters from a file only if the file has 'xyz' in field 185-188.
I tried this
cat filename | cut -c1-10
but this gives me all the records regardless of what is in field 185-188.
Is this doable ?
Thanks in advance for responses. (2 Replies)

gpiv_process-chain
GPIV_PROCESS-CHAIN(1) General Commands Manual GPIV_PROCESS-CHAIN(1)NAME
gpiv_process-chain - Processes a pipe of Gpiv-tool command's.
SYNOPSIS
gpiv_process-chain [-af string] [-h | -help] [-n | -none] [-c | -clean] [-fik] [-p | -print] [-pf -string] [-proc_*] [-t format] [-v |
-version] filename
DESCRIPTION
Gpiv_process-chain processes a pipe of gpiv commands. Image evaluation/interrogation with gpiv_rr is always included, image recording may
be prepended before interrogation, validation and post-processes may be appended to the chain. The filename represents the name of the
image to be evaluated. The file naming conventions are idententic to the output of the individual Gpivtools programs: in case the output
are (validated/scaled) PIV data, the data will be directed to filename.piv, with -proc_vorty the output will be called filename.vor, with
-proc_nstrain the output will be called filename.nstr and, finally, with with -proc_sstrain the output will be called filename.sstr.
This program does not use the parameter resources from libgpiv.
Options-af string Append string to file-base name.
-h | --help
On-line help.
-n | --none
Suppresses real execution.
-c | -clean
Cleans up: removes raw image data and header.
-fik Use fi-keyline for filtering gpiv parms from README.
-p | --print
Prints parameters, command line options and input and output filenames to stdout.
-pf string
Prepend string to file-base name.
-proc_*
Defines processes to be included in the chain. * is substituted by: imgrec, valid, scale, manipiv, flipx, flipy, revert, rot90,
rot180 and vorty or nstrain or sstrain. Vorty, nstrain and sstrain may not be used in combination with -t gpi.
-t format
Image type or format: hdf (.hdf), dav (.IMG) or a type as defined by ImageMagic's convert. Default is raw binary image (.r).
-v | --version
Prints version information to standard output, then exits successfully.
filename
Input image filename. Format may be: .r, .hdf (hdf), .IMG (davis), .png, .gif, .tif or.bmp.
EXAMPLES
invoking: 'gpiv_process-chain -proc_valid -proc_scale testfile.png' will actually perform: gpiv_rr < image.png | gpiv_errvec > testfile.piv
invoking: 'gpiv_process-chain -proc_imgrec -proc_valid -proc_scale testfile.png' will do: gpiv_recimg | gpiv_rr | gpiv_errvec | gpiv_scale
> testfile.piv
