Try this.

Code:
cgi@tonga> (/home/cgi) $ gawk    --posix '/[A-Z][A-Z]{3,4}-[0-9]{5}/ {print}' test.txt
ABCDE-12345
abc BCDA-12345
defe erjhj ABCD-12345
dfjfh sdhjh jkfgh dfj aaaAAAA-12345
cgi@tonga> (/home/cgi) $

You have to use --posix to use any posix regex


To extract those fields, you could try:
Code:
cgi@tonga> (/home/cgi) $ awk -F"[a-z ]" '{print $NF}' test.txt
ABCDE-12345
BCDA-12345
ABCD-12345
AAAA-12345

This is the final shot, this should will extract the patterns
Code:
cgi@tonga> (/home/cgi) $ cat test.txt
ABCDE-12345
abc BCDA-12345
defe erjhj ABCD-12345
dfjfh sdhjh jkfgh dfj aaaAAAA-12345
sijefisfej AAAA-12345sefsfsef
sijefisfejAAAA-12345sefsfsef


cgi@tonga> (/home/cgi) $ gawk --posix -F"[a-z ]" '{for(i=1;i<=NF;i++){if($i~/^[A-Z][A-Z]{3,4}-[0-9]{5}/){print $i} }}' test.txt
ABCDE-12345
BCDA-12345
ABCD-12345
AAAA-12345
AAAA-12345
AAAA-12345
cgi@tonga> (/home/cgi) $

Hello All, I have been using String.h with gcc 2.95. Now I have upgraded to gcc 3.4. The support for String.h has been removed and I believe Regex.h support is also not inbuilt.

upsimage.cgi

UPSIMAGE.CGI(8) 						    NUT Manual							   UPSIMAGE.CGI(8)

NAME

       upsimage.cgi - Image-generating helper for upsstats.cgi

SYNOPSIS

       upsimage.cgi

	   Note
	   As a CGI program, this should be invoked through your web server. If you run it from the command line, it will either complain about
	   unauthorized access or spew a PNG at you.

DESCRIPTION

       upsimage.cgi generates the graphical bars that make up the right side of the page generated by upsstats.cgi(8). These represent the current
       battery charge, utility voltage, and UPS load where available.

       The images are in PNG format, and are created by linking to Boutell's excellent gd library.

ACCESS CONTROL

       upsstats will only talk to upsd(8) servers that have been defined in your hosts.conf(5). If it complains about "Access to that host is not
       authorized", check that file first.

FILES

       hosts.conf(5)

       upsd(8), upsstats.cgi(8)
