Grep userids
Hey, what's the best way to use grep to list all userid's on the system that do not contain the "." character (period). Also, could I edit the same command to list all the userid's on the system that are 10 or more characters in length. Thanks, I'm not that familiar with grep, but I know it can do a lot.

Will userids make a difference in performance?

I have nearly 10 users who login into the HP server (D series, HP UX 10.20) with the same UNIX user name, "liveuser", and they start the UNIX based transactions. If I create separate UNIX user-ids for all the 10, will the system performance improve? (1 Reply)

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.
