how to get rid of ' from variable?
hi,

I want to get rid of ' from my variable value in ksh, and I also want to read the value on the right hand side of = into a variable

thanks

Question is not very clear but here is what I think you are after:
Code:
$ AJF=\'fred\'; export AJF
$ env | grep AJF
AJF='fred'

We have a variable whose value includes the ' character.

To extract the value from the above do:
Code:
$ echo $AJF | awk -F"'" '{ print $2 }'
fred
$

To put the extracted value into a new variable do:
Code:
$ BHG=`echo $AJF | awk -F"'" '{ print $2 }'`
echo $BHG
fred
$

This should work too if you have one or more quotes in the variable:

Code:
var=$(echo $test | awk '{gsub("\047","")}1')

Code:
$ var="'test'"
$ echo $var
'test'

How about:
Code:
$ eval var=$var
$ echo $var
test

A built in ksh functionality for what? To remove the sigle quote character from a variable? To extract the characters after the = sign?
What version of the Korn Shell are you using: ksh88, ksh93, pdksh?
