Hi rdrtx1,
Unfortunately, the above script won't match 80%, 90%, or 100%. One could use:
but I find the suggestions provided by RavinderSingh13 and MadeInGermany easier to read.
I don't know of any versions of awk written since 1980 that won't accept $5+0 to strip off the trailing percent sign and then perform a numeric comparison (as required by the standards), but if you run into an awk that doesn't handle that correctly, MadeInGermany's approach will handle those cases while Ravinder's approach won't. I don't remember for sure whether or not the original awk written in the 1970's by Aho, Weinberg, and Kernighan handled this case or not; but I thought it did.

Could someone tell me how to perform calculations using numbers greater than 2150000000 in Korn Shell? When I tried to do it it gave me the wrong answer.
e.g. I have a ksh file with the contents below:

Hi, as the title states i need to find a way to search a column for values great than 1000, and if it is, then delete that row.

Hi again. Sorry for all the questions — I've tried to do all this myself but I'm just not good enough yet, and the help I've received so far from bartus11 has been absolutely invaluable. Hopefully this will be the last bit of file manipulation I need to do.

spi_modifytuple
SPI_MODIFYTUPLE(3) PostgreSQL 9.2.7 Documentation SPI_MODIFYTUPLE(3)NAME
SPI_modifytuple - create a row by replacing selected fields of a given row
SYNOPSIS
HeapTuple SPI_modifytuple(Relation rel, HeapTuple row, int ncols,
int * colnum, Datum * values, const char * nulls)
DESCRIPTION
SPI_modifytuple creates a new row by substituting new values for selected columns, copying the original row's columns at other positions.
The input row is not modified.
ARGUMENTS
Relation rel
Used only as the source of the row descriptor for the row. (Passing a relation rather than a row descriptor is a misfeature.)
HeapTuple row
row to be modified
int ncols
number of column numbers in the array colnum
int * colnum
array of the numbers of the columns that are to be changed (column numbers start at 1)
Datum * values
new values for the specified columns
const char * Nulls
which new values are null, if any (see SPI_execute_plan for the format)
RETURN VALUE
new row with modifications, allocated in the upper executor context; NULL only if row is NULL
On error, SPI_result is set as follows:
SPI_ERROR_ARGUMENT
if rel is NULL, or if row is NULL, or if ncols is less than or equal to 0, or if colnum is NULL, or if values is NULL.
SPI_ERROR_NOATTRIBUTE
if colnum contains an invalid column number (less than or equal to 0 or greater than the number of column in row)
