I have data, from which I want to grep for two fields. Only pull out the data if both the fields exist.
I have used: egrep --text "field1|field2" file > temp. This seems to be doing an OR. What I am after is an AND. (10 Replies)

Hi all,
Currently I have this:
ps -eo pid,comm| grep CSORDB1T
But I need to grep LOCAL=NO as well:
ps -eo pid,comm| grep CSORDB1T |grep LOCAL=NO >pdwh_pid
However, there's no output. Plz advise how can we grep CSORDB1T & LOCAL=NO at the same time.
Thanks! (8 Replies)

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. AUTHOR
