awk command to print only selected rows in a particular column specified by column name
Dear All,
I have a data file input.csv like below. (Only five column shown here for example.)
From this I want the below output
where the second column StepNo contents are '1'.
I used the below simple script to get this output.
But many times the second column is not always StepNo as there are many versions of input files with varying column positions and total number of columns. So I need a script(with awk) to get my required output byspecifying column name instead of referring from column number .

Random data
Name-Number-ID
Sarah-2.0-15
Bob-6.3-15
Sally-1.0-10
James-1.0-10
Scotty-10.7-15
So I would select all those who have ID = 15 and then add up total number
read - p "Enter ID number" Num

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.
