Full Discussion: Find EXACT word in files, just the word: no prefix, no suffix, no 'similar', just the word
Top Forums UNIX for Dummies Questions & Answers Find EXACT word in files, just the word: no prefix, no suffix, no 'similar', just the word Post 302613985 by Scrutinizer on Wednesday 28th of March 2012 05:59:45 AM

What happens when you use
Code:
grep -w Sun file

It should work:
Code:
$ echo "Sun
Sunny
It is Sunday, let's
" | grep -w Sun
Sun

So perhaps there is an extra character between Sun and ny in the file you are searching in? Have you checked with od -c?
Otherwise what is your OS and version?

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.
