Print from second column onwards if $1<=40 using awk
I have a file like below

Code:
10 10 21 32 43 54  
20 10 25 36 47 58
30 19 20 31 42 53
40 10 24 35 46 57
50 10 28 39 40 51

I need to check if $1 <= 40, then print from $2 onwards.
If $1 > 40, the line is not printed.

So I would have an output like this

Code:
10 21 32 43 54  
10 25 36 47 58
19 20 31 42 53
10 24 35 46 57

if the no of fields will be 6 always,
the simple soln is:

Code:
/home->awk '$1<=40{ print $2,$3,$4,$5,$6}' f
10 21 32 43 54
10 25 36 47 58
19 20 31 42 53
10 24 35 46 57
/home->

The problem is that I cannot directly use $2 $3 $4 one next to each other. I can have any number of fields on each line.

Try this:
Code:
awk '$1 <= 40{ $1=""; $0=$0; $1=$1; print}' file

Code:
awk '$1<=40 { $0=substr($0, index($0,$2)); print $0 } 
       $1>40 {print $0 } ' infile > outfile

I have tried this

Code:
$1 <= 40 {
  $1 = ""; sub(/^[ \t]+/, ""); print
}

then you can try something like this:
Code:
/home->awk '$1 <=40{ $1="";record=$0; gsub("^ ","",record);print record }' f
10 21 32 43 54
10 25 36 47 58
19 20 31 42 53
10 24 35 46 57
/home->
