Unix parsing pipe delimited format string in ksh

Question

I am writing ksh script to parse a pipe delimited string

export dummy=\"abc\"  
echo \"123|456|789\" | awk \'{split($0,output,\"|\"); print output[3] output[2] o         


        

Answer 1

You can't assign awk variables (i.e. output[3]) to shell variables (i.e. dummy), you can only assign the output of awk to a variable, e.g.

export dummy=`echo "123|456|789" | awk -F'|' '{ print $3; }'`

However, awk is a bit overkill here, cut will work just as well:

export dummy=`echo "123|456|789" | cut -d'|' -f3`
