Passing a parameter to AWK

Hi All,

I am trying to pass a parameter to AWK on my KSH shell prompt as below.

var1=2
echo $var1
awk -v var2=${var1} '{print var2}' testfile.txt

I am passing the input file (testfile) to awk to get some o/p. It is having 10 records.

When I run AWK, it is throwing the following errors
awk: syntax error near line 1
awk: bailing out near line 1

I googed this forum, the syntax i am using is correct, but dont know why it is failing in this case.

My OS is SOLARIES,is there any difference syntax for AWK for passing parameters to AWK on sun solaries?

Can any one please help.

Hi All,

It got solved. The correct syntax is

awk '{print var2}' var2="$var1" test111.xls

I think there is syntax change in Sun solaries from BASH it seems.

In bash, generally we pass -v option before print, but in solaries, this is working if I use -v option after print.

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
