In above data we have two distinct values in column 1 which are C1 and C2. We have three distinct values in column 3 which are K1, K2 and K3. I will grep the file three times (K1, K2 and K3) for each C (C1 and C2). After grep I will replace C5 of line n by C4 of line n+1 until C5 of line n+1 is not zero.
using while loop this can be done but it will be slow. Is there any awk command which will be quicker?
Please help.
Thanks

I generally use yy to copy a line and then p to paste the line at end of current line.
But is there a way to paste the copied line in concatenation with the current line with out going to next line. (3 Replies)
How would you do vim copy line and paste at the beginning, middle, and end of another line. I know yy copies the whole line and p pastes the whole line, but on its own separate line. Sometimes I would like to copy a line to the beginning, middle, or end of another line. I would think this would be... (3 Replies)

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
