Command/script to match a field and print the next field of each line in a file.
Hello,

I have a text file in the below format:
Code:
Source                                                                                              Destination                                                                              State          Lag        Status
CQA02W2K12pl:D:\CAQA                                                                            infrabkpsrvpl:/vol/CQA02W2K12srv/CAQA                                                Snapvaulted    13:46:44   Idle
DBIntranetpl:E:\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL                                  infrabkpsrvpl:/vol/DBIntranetsrv/MSSQL10                                                Snapvaulted    13:46:43   Idle

And the file has hundreds of such entries.

What I'm interested in is the lag column- which is always in the format hh:mm:ss. I want to read the file line by line, check if the "lag" column in greater than 48:00:00 (just matching the hour field would be enough) and if the lag is greater than 48:00:00, append that particular line to another file.

How can I achieve this?

I tried awk, but since some of the line descriptions have spaces, $4 is not always lag column.

Thanks,
Pocodot

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.
