UNIX for Dummies Questions & Answers

Can any one please say about the below,

using,
grep -v "name" file.txt
the result of above command will be it will print all the lines except the line which having the word "name"

similarly,
nawk 'c-->0;$0~s{if(b)for(c=b+1;c>1;c--)print r[(NR-c+1)%b];print;c=a}b{r[NR%b]=$0}' b=0 a=1 s="name" file.txt

from above command i wil get the output as,
it will print all the lines which having "name" word and also the next line to it.

What i want is, similar to grep -v what is the option for nawk to get the output as , other lines EXCEPT the word "name" and the next line to it in nawk.

Code:

awk '!/name/{print}' filename

this will print all the lines which doesnot contain "name"

Code:

awk 'c-->0;/name/{c=1}' filename

this will print all the next line where the pattern "name" is found

Thanks vidyadhar85 for ur reply but i need to print all the lines except the line havin word and its next line..

u gave seprate commands but i need a single command which does both the thing.

Code:

home> sed '
> /name/{
> N
> /\n/d
> }' inputfile

#!/bin/ksh
i=`date +%d`
sed `/WARNING:Below field is not in File name/{N/\n/d}' load.$i >> load_new.txt


Using ur script i gave lik above but i am getting the following error,
-----------
/WARNING:Below: not found
-----------

I am seraching for "WARNING:Below field is not in File name" in load.<current day> and the next line of it and then redirecting tat o/p to load_new.txt

coul u please help me out?

buddy write it in this way and you used backstick "`" after sed make it single quote "'"

Code:

#!/bin/ksh
i=`date +%d`
sed '
/WARNING:Below field is not in File name/{
N
/\n/d
}' load.$i >> load_new.txt

Thanks Tutor. It worked fine.
