Hey all,
I'm looking for some with awk.
Our Midrange (unix) team just upgraded our lpar from aix 5.1 to 5.2ML6
Since the upgrade my awk -v option has stopped working.

The syntax below will find the literal value "M" in the ps list, not
the contents of variable $CS.

for CS in R1 R3 A1 A3
do
CSPID=`ps -ef|awk -v M=$CS '/M/ && /exec/ && !/awk/ {print $2}'`

Have I been getting away with incorrect syntax all along or is there
really a bug?

Any insight would be ful.

Thanks,
Roger

Your syntax is wrong. The above would search for the character "M" not
the value of the variable "M". What you want is:

awk -v M="$CS" '($0 ~ M) && /exec/ && !/awk/ {print $2}'

Most likely.

The right syntax would more look like:

$(ps -ef | awk -v M=$CS 'match($0, X) && /exe/ && !/awk/ { print $2}')

Both examples worked perfectly !!
Thanks Guys.

I know it doesn't make it right, but my syntax did work in AIX 5.1
