I missed the column in the input.

Code:

Input with columns
994475;1832 +  S PP1835 10/17/18;S;P201835;115;N;4,4;M;0;xx994475;*;BA7005;10/17/2018 16:48
994477;1836 +  S PP1839 10/17/18;S;P201839;115;N;4,4;M;0;xxh994477;*;BA7005;10/17/2018 16:48
994479;CONTROL 1452-1527,1552-1627;S;P201527;115;N;4,4;M;0;RHS_12_1515FF_0706;*;B7005;10/17/2018 16:49

I changed all column in the expected output. If you see in column 4 I have change P201835 to P201829. For column 2 and 10. It is like changing the YYYY , If you look I changed 1832 to 1826. And in Column 10 for last row I changed from RHS_12_1515FF_0706
to RHS_12_1510FF_0706

Ran it and created a same ouput as original

Code:

(K>)  awk -f change.awk input.csv
994479;CONTROL 1452-1527,1552-1627;S;P201527;115;N;4,4;M;0;RHS_12_1515FF_0706;*;B7005;10/17/2018 16:49
(K>) cat input.csv
994479;CONTROL 1452-1527,1552-1627;S;P201527;115;N;4,4;M;0;RHS_12_1515FF_0706;*;B7005;10/17/2018 16:49

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.

BSD
								  August 4, 2004							       BSD
