You have a data inconsistency in your sample file: the header line has six fields, while the data rows have seven. I had to eliminate that in order to have following work. Try
Hi All,
Am working on perl script which should delete columns in existing CSV file.
If my file is :

Hi,
I want to delete rows that dont have a certain # of columns. In my case, rows that are less than 8 should be removed (those greater than 8 are ok).
For instance:

Hi all, I know this sounds suspiciously like a homework course; but, it is not.
My goal is to take a file, and match my "ID" column to the "Date" column, if those conditions are true, add the total number of minutes worked and place it in this file, while not printing the original rows that I... (6 Replies)
Hi all, I'm pretty much a newbie to UNIX. I would appreciate any help with UNIX coding on comparing two large csv files (greater than 10 GB in size), and output a file with matching columns.
I want to compare file1 and file2 by 'id' and 'chain' columns, then extract exact matching rows'... (5 Replies)

tiffreadscanline
TIFFReadScanline(3TIFF)TIFFReadScanline(3TIFF)NAME
TIFFReadScanline - read and decode a scanline of data from an open TIFF file
SYNOPSIS
#include <tiffio.h>
int TIFFReadScanline(TIFF *tif, tdata_t buf, uint32 row, tsample_t sample)
DESCRIPTION
Read the data for the specified row into the (user supplied) data buffer buf. The data are returned decompressed and, in the native byte-
and bit-ordering, but are otherwise packed (see further below). The buffer must be large enough to hold an entire scanline of data. Appli-
cations should call the routine TIFFScanlineSize to find out the size (in bytes) of a scanline buffer. The row parameter is always used by
TIFFReadScanline; the sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).
NOTES
The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native
machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automati-
cally byte-swapped if the file was written with a byte order opposite to the native machine byte order,
In C++ the sample parameter defaults to 0.
RETURN VALUES
TIFFReadScanline returns -1 if it detects an error; otherwise 1 is returned.
DIAGNOSTICS
All error messages are directed to the TIFFError(3TIFF) routine.
Compression algorithm does not support random access. Data was requested in a non-sequential order from a file that uses a compression
algorithm and that has RowsPerStrip greater than one. That is, data in the image is stored in a compressed form, and with multiple rows
packed into a strip. In this case, the library does not support random access to the data. The data should either be accessed sequentially,
or the file should be converted so that each strip is made up of one row of data.
BUGS
Reading subsampled YCbCR data does not work correctly because, for PlanarConfiguration=2 the size of a scanline is not calculated on a per-
sample basis, and for PlanarConfiguration=1 the library does not unpack the block-interleaved samples; use the strip- and tile-based inter-
faces to read these formats.
