Top Forums Shell Programming and Scripting Can a variable assigned in a shell function be accessed outside Post 302369987 by bittoo on Tuesday 10th of November 2009 05:38:11 AM

OK..Lemme be clear,
My script:
Code:
#!/bin/ksh
compare()
{
cat $1>t1
cat $2>t2
cy1=`cut -f13 -d'Ç' t1`
cy2=`cut -f13 -d'Ç' t2`
if [ $cy1 = $cy2 ]
then
  echo "yes"
else
  echo "no"
fi
}
d3=$(compare temp1.rm temp2.rm)
print $d3 <== Prints "yes" as cy1 and cy2 are equal.
echo $cy1 <== Is null.

I need to manipulate some part of the script using value of d3 and use value of cy1 down the script. How can I use the value for cy1 later??

Thx for the help !!!!
