Shell Programming and Scripting

Hi raokl,
This is only a method that I thought without test.

Code:

echo $a|awk '{i=1;while($i){if($i~/[*?]/){printf "%s",$i;exit};i++}}' FS=','

Hi Lucas,

Aswesome, It worked for me now with your updated changes.

Thank you very much, I really appreciate all your help & gudiance on this.

There are a couple of options from me using internal ksh functions and tr which for a large number of loops through could be quicker than echo.... | awk .... as it doesn't have the overheads to repeatedly start new processes, but if you have the strings as a large input file, you could use tr:-

Code:

tr -d "*?" < in_file

If you have the strings as a large input file, you could use tr twice in a pipeline.

Code:

tr -d "*?" < in_file | tr -s "," > out_file

I hope that these suggestions help.
