vgresh thank you. i'm goign to see if i can use your code. The file in question actually has 1.3million rows (tab delimited). the source column is number 35, and I need to append the 123 and abc column as two new columns to the end of the file.

I should also add it is possible that something that would need to be parsed to the abc column is: < 3.2

currently only the abc values are moved to a new column. I also need the 123 values to move to their own distinct column.
in addition I need to copy these values to new columns and retain them in the source column.

From googling and reading man pages I figured out this sorts the first column by numeric values.
sort -g -k 1,1
Why does the -n option not work? The man pages were a bit confusing.
And what if I want to sort the second column numerically? I haven't been able to figure that out. The file... (7 Replies)

colrm
COLRM(1) BSD General Commands Manual COLRM(1)NAME
colrm -- remove columns from a file
SYNOPSIS
colrm [start [stop]]
DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read
from the standard input. Output is written to the standard output.
If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec-
ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not
zero.
Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).
EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO awk(1), column(1), cut(1), paste(1)HISTORY
The colrm command appeared in 3.0BSD.
