Well, it worked fine on my Linux-box, but as soon as I moved it over to my really old Solaris server (Solaris 10 8/07) I get

Code:

awk: too many output files 10
 record number 55

So, based on info found elswhere on this forum, I tried to use nawk instead:

Code:

nawk '/^ ABC_/{g++; f=$1} {print $0>f; close(f)}' largefile.txt

But this gives me just empty files... Is there a workaround for my script when it comes to this limitation of 10 open files in Solaris? Can I tweak the script in some way?

---------- Post updated at 11:53 AM ---------- Previous update was at 11:00 AM ----------

I got past the number of open files limitation by using the POSIX compliant awk instead of the awk that is in the solaris standard path (/usr/bin/awk):

Code:

/usr/xpg4/bin/awk '/^ ABC_/{g++; f=$1} {print $0>f}' largefile.txt

DPKG-AWK(1)						      General Commands Manual						       DPKG-AWK(1)

NAME

       dpkg-awk - Utility to read a dpkg style db file

SYNOPSIS

       dpkg-awk [(-f|--file) filename] [(-d|--debug) ##] [(-s|--sort) list] [(-rs|--rec_sep) ??] '<fieldname>:<regex>' ... -- <out_fieldname> ..

DESCRIPTION

       dpkg-awk  Parses  a  dpkg status file (or other similarly formatted file) and outputs the resulting records.  It can use regex on the field
       values to limit the returned records, it can also be told which fields to output, and it can sort the matched fields.

OPTIONS

       -f filename
       --file filename
	      The file to parse.  The default is /var/lib/dpkg/status.

       -d [#]
       --debug [#]
	      Each time this is specified, it increased the debug level.

       -s field(s)
       --sort field(s)
	      A space or comma separated list of fields to sort on.

       -n field(s)
       --numeric field(s)
	      A space or comma separated list of fields that should be interpreted as numeric in value.

       -rs ??
       --rec_sep ??
	      Output this string at the end of each output paragraph.

       -h
       --help Display some help.

       fieldname
	      The fields from the file, that are matched with the regex given.	The fieldnames are case insensitive.

       out_fieldname
	      The fields from the file, that are output for each record.  If the first field listed begins with ^, then the list  of  fields  that
	      follows will NOT be output.

BUGS

       Be  warned  that  the author has only a shallow understanding of the dpkg packaging system, so there are probably tons of bugs in this pro-
       gram.

       This program comes with no warranties.  If running this program causes fire and brimstone to rain down upon the earth, you will be on  your
       own.

       This program accesses the dpkg database directly in places, querying for data that cannot be gotten via dpkg.
