running on sol10.

i ended up not using the "short cut" way with
Code:
egrep pnj-sansw124-'([0-9]\{1\}|[0-9]\{2\})'

so i changed it to
Code:
egrep pnj-sansw124-([0-9]|[0-9][0-9])/

this seems to work. however, obviously we start running into problems with higher numbers or more then two digit numbers. i don't feel like running all those ranges out. but for purposes for what i need it for now, its good. i'll fine tone it later with your suggestion.

now with grep -E, i fail. it didn't like that. egrep is good though.

thanks for the help. let me get to work and give it a go.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
