The sample you posted earlier seems to have a header line. And DOS line terminators (<CR> = \015 = 0x0D = \r = ^M). Try
awk -F "\t" '
{sub ("\r","")
}
NR == 1 {N = split ($0, HD);...

How about

awk -F "\t" '
{for (N=1; N<=NF; N++) if ($N!="") CNT[N]++}
END {for (N=1; N<=NF; N++) print "col" N ":", CNT[N]
}
' /tmp/ex.txt
col1: 10
col2: 10
col3: 10...

Neither ... nor. The $1 = $1 trick replaces ALL field separators (multiples as well) with the OFS char without modifying the fields' contents. man awk:

While rdrtx1's proposal works fine for the samples given, it doesn't for the duplicates mentioned as the samples don't have any. Nor is the request for <TAB> field separators in the result fulfilled....

That will work with some versions of awk and give you a syntax error with other versions of awk. The following should work with almost any version of awk:
awk '{$1=$1; print>("file"NF)}'...

Yoda gave you directions on how to turn off color for a particular invocation of ls (assuming that you're using a Linux system).

To turn it off permanently for future invocations of ls, we need to...

Can switch off color and try:
ls --color=never

Try:
awk 'NR==FNR {d[$0];next} ! ($0 in d) {print}' fileB.txt fileA.txt

Since the script I gave doesn't know what files will be passed in as arguments, thels PUR.*won't work in the general case. But, if you change:
awk 'BEGIN {
fc = -1
}
FNR==1 {fc++
}
in the...

The solution provided my mirni seems to work OK except that it doesn't print the key at the start of each output line. (It also prints the 0 value as 0.000, but I don't see why that really matters.)...

Sorry but few adding question :

Which foo entry does NOT need to be displayed :

1. Any foo entry that has his rs# NOT in bar ?
2. Any foo entry that has his [0-9]# NOT in bar ?
3. Any foo...

Sure,
I'll try.

The code is:

awk 'END {
for (i = 0; ++i <= idx;)
printf "%s\n\n", p[i]
if (p[i - 1] != r)
print r
}
/\$newpage/ {
sub(/\n\n*$/, x, r)
t[r]++ ||...

OK, try this:

awk 'END {
for (i = 0; ++i <= idx;)
printf "%s\n\n", p[i]
if (p[i - 1] != r)
print r
}
/\$newpage/ {
sub(/\n\n*$/, x, r)
t[r]++ || p[++idx] = r
r...

Try this:


awk ' /ZIP/ {next;} $NF < .05 { printf( "%s %s\n", $0, FILENAME ); }' *.results >new.file


Adds the filename as the right most column to each output line. Does discards the header...

awk 'NR==FNR{s=$1; sub(".*"$2,"");a[s]=$0; next} a[$1]{print $0 a[$1]} ' bar.txt foo.txt

Explanation:
NR==FNR

If we read the first file.
s=$1

Capture the first field in variable s to use...

Or:
awk 'NR==1{print;next} $5=="ADD"{print | "sort -grk9"}' OFS="\t" file

nawk 'FNR==1{print >out;next}$5=="ADD" {print $0}' OFS='\t' out=Assoc_sorted.TXT Assoc.txt |sort -gk9 >>Assoc_sorted.TXT

Yes,
in this case the number of arguments (input files) is limited only by your system (MAX_ARGS kernel limit).

As far as the script is concerned, the filenames are irrelevant,
just pass the...

Just to clarify that I wrote all that code only because of this requirement:




:)

Given your sample data, the following script:

awk 'END {
for (R in rec) {
n = split(rec[R], t, "/")
if (n > 1)
dup[n] = dup[n] ? dup[n] RS sprintf("\t%-20s -->\t%s", rec[R],...

Indeed, that was the only issue:
$ awk 'NR==FNR{A[$2]=$3;next} $2=A[$1]' OFS="\t" bar foo
451 volkswagen

awk 'NR==FNR{a[$0];next} $2 in a {print $2,$4}' OFS='\t' foo bar > barfoo

It is a problem with tty settings - how bash reads keystrokes from the terminal.

Look for the word "erase" followed by some goofy character(s) in the output of:

stty -a


You want that to be...

You use wrappers when you want to enhance the functionality of an existing utility/command without changing it (usually for backwards compatibility or because you don't have access to the original...

If your ranges get bigger, then it as an alternative to egrep you can use anbu's solution provided your input file is numerically sorted on the first column, e.g.:awk '$1 == 21, $1 == 25; $1 == 101,...
