It is taking too long to get a string from in1.text, search for the string in in2.txt and create a new file out1.txt.
Is there any alternative way we can achieve the same faster?
Thanks in advance
Moderator's Comments:
Please use CODE tags rather than ICODE tags when displaying code with more than 1 line or with a single line that might be split due to line length.

Reason: Changed ICODE tags to CODE tags.
As I know:
FNR: The ordinal number of the current record in the current file.
NR: The ordinal number of the current record from the start of input.
I don't understand really differency between NR and FNR. Who can explain it for me? And give me an example.

Hi Guys,
I have two files:
f1:
A B C D E F G H
f2:
A X Y Z
f1 has 48000 lines, and f2 has 68. I have been matching f1 $3 to f2 $1, and getting f3:
A A B C D E F G
I would like f3 too look like this:
A X Y Z A B C D E F G (2 Replies)
cat file1
1 a b c
2 d e f
3 a f r
cat file2
a c e
output should be
1
3
means:
if field 1 of file2 matches filed 2 of file1 then print field 1 of file1
I know that it can be done using awk NR=FNR.
But not able to acheive it.
Thanks in advance. (9 Replies)
awk -F'' 'FNR==NR {a=$2; next} {$1=a} 1' $useralias ${entries} >> ${entries}_2
Hi,
Is there anyway to alter this command so that if it does not find a match it will just leave the line alone instead of replacing what it doesn't find with a blank space? (4 Replies)
This has been asked and answered hundreds of times, but I can't understand the syntax of awk's NR==FNR trick for merging files and printing the correct columns.
