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.
Thanks (1 Reply)
Multiple versions of this are probably in this section, but could not find one just right for me. My code gives me a zero byte file.

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)

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.

Hi,
I have an issue with the below script
nawk 'NR==FNR{a=$4" "$5}NR>FNR{print NF?$0:a"\n";if(/^cn:/) x=$0}' FS="" in1.txt in2.txt > out1.txt
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... (1 Reply)

xzcmp
XZDIFF(1) XZ Utils XZDIFF(1)NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
SYNOPSIS
xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed
directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com-
pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom-
pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved.
The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.
SEE ALSO cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
