I have text file with hundreds of lines, space delimited, each line has the same amount of "columns" and the same amount of characters in each, Column 1, Column 2, and Column 3.
I need a script that will print all columns of the "current" line along with the last two columns of the next line ONLY IF the first columns are equal.
Another way of putting it...
If Column1CurrentLine equals Column1NextLine
print AllOfCurrentLine Column2NextLine Column3NextLine
So my input has 3 columns and my output would have 5 total but only 3 in some lines?
input:
output:

Hi
I have a file with multiple columns. But there is something weird on column one that is attached to the name. The good thing is that its a consistent pattern so there should be a way to remove it.
So the first column looks something like this:
name_345.4ml
date_3456.4ml
year_12.4ml... (3 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.
