I am not manipulating anything here, it worked fine in Solaris and Linux.
Code:
cgi@tonga> (/home/cgi) $ echo GAPI-53137 | awk --posix -F"[^A-Z0-9-]" '{for(i=1;i<=NF;i++){if($i~/^[A-Z][A-Z]{3}-[0-9]{5}/){print $i} }}'
GAPI-53137
cgi@tonga> (/home/cgi) $
cgi@tonga> (/home/cgi) $

Try this inyour machine and post the output

Code:
echo GAPI-53137 | awk --posix -F"[^A-Z0-9-]" '{print $1}'

It seems that standard awk in solaris doesn't support such expression matching  ( re-interval one)



At least i hope this works






Code:



echo GAPI-53137 | awk --posix -F"[^A-Z0-9-]" '{for(i=1;i<=NF;i++){if($i~/^[A-Z][A-Z][A-Z][A-Z]-[0-9][0-9][0-9][0-9][0-9]/){print $i} }}'







Please say it works
