anchoring regex using case and ksh
Outside this process I built a file containing snmp response filtering for hostname, model type and ios version.
I want to get a count across the network of those devices running 11.x code, 12.0 mainline, 12.0 T train and above, 12.1 and above and OS levels.
This works ok .. but its cheap
How can use case ? the obvious didnt work. I guess I dont know how to anchor the regex.
grep " 11\.[0-9]" seedfile$hf > 11_$hf
grep " 12\.0" seedfile$hf | grep "]$" > 12_0_$hf
grep " 12\.0" seedfile$hf | grep -v "]$" > 12_1_$hf
grep " 12\.[1-9]" seedfile$hf >> 12_1_$hf
grep " [1-9]\.[1-9]\{1,\}" seedfile$hf > 7_$hf

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
