awk and fuction (recursion) !! Urgent !! - UNIX for Advanced & Expert Users

varungupta · #1 (**permalink**) 02-08-2008

Hey all,

Could you please check following way of writing awk is correct or not ???

-----------------------------------------------------------

Quote:

pattern= "mqsi[admtspr]"

cat tempgrep.txt | \
while read ppid
do
awk '{
recurcive_fun(ppid, pattern)
function recurcive_fun(n, pattern)
{
awk '{ if ($2~n && $1~pattern){
n=$3
recurcive_fun(n, pattern)}
else{
if ($2~n && $1!~pattern){
print $1 >> "tempmail.txt"
break
}
else {next}
}
}' tempfind.txt
}
}'
done

-----------------------------------------------------------------

Its recursion being called.

tempgrep.txt has :
462948
1311040
880922

tempfind.txt has :
t2589vg 880922 462948 09:57:07 -ksh
mqsiadm 1298856 1311040 09:57:56 -ksh
mqsiadm 1311040 880922 09:57:19 -ksh

Please suggust/correct the script(if wrong) !!
Thanks
Varun

awk does not know about pattern:
awk -v pattern=$pattern"

Use the -v option. Plus pattern is misspelled as "pettern".

Please use code tags when you post code.

hey,

Thanks for reply

Could you please tell me where i should mention -v option in awk, as awk is used twice in the code ? Now, how my script should look like ?
Thanks, I did notice the typo error for pattern. Thanks anyways.
And when i was running the above script then it given me error saying:Syntax error at line 11 : `(' is not expected.

Please tell me.

Hey,

I have a dummy script that is the base for the above script where I am getting the problem of syntax.
Dummy script is working fine and is given below, but i dont know why the actual script is not working :

-------------------------------------------------------------------
for var in 1 2
do

echo "var : $var"

count=0
while [ "$count" -lt 3 ]
do
echo "count : $count"

awk 'BEGIN { i = 0
f(i)
}
function f(para)
{
if ( para < 10 )
{
print "\n value of para : " para ;
para += 1 ;
f(para) ;
}
else
{
print "\n inside else, before increment, para : " para ;
para += 1 ;
print "\n inside else, para : " para ;
exit ;
}
}
'
let "count += 1"
done
done

-------------------------------------------------------------------

Please have a look and suggest any solution to the problem.
Thanks to all the unix bonds.

Varun Gupta.
