Grep from multiple files
Hello,
How do I grep from multiple, specific file names. For example I have a directory that has numerous files named bsm0a.alarm_output.xxxxxx (the x's will be the date).
I need to be able to grep any string that contains the acronym ACN or the word packets, but I will only need them from specific files. For example, I need to be able to grep from bsm0a.alarm_output.051009, bsm0a.alarm_output.051109 & bsm0a.alarm_output.051109 and nothing else.
Thanks.

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.
