Top Forums UNIX for Dummies Questions & Answers Grep from different folder Post 302085186 by nathan on Tuesday 15th of August 2006 11:57:46 PM

It's not clear to me where the 4 folders come into the equation. Does the log file exist in all folders? ( There are 4 copies of the log file, one in each folder? )

If so, you can do something like
Code:
gzcat folder1/logfile.gz folder2/logfile.gz ... | grep expression

Or you can decompress the files and do
Code:
grep expression folder1/logfile folder2/logfile ...

zegrep

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.
