Re: Shell Script Required? Pls. help me

Try this, I am sure there are shorter ways to do this, but this one works fine and is easy to follow

Code:
#!/bin/sh

declare -i lineno
declare -i hadmatch=0
while read line; do
    #echo $line
    #match=`echo $line | grep 'NMInterface'`
    match=`echo $line | grep '^+*\s*NMInterface\s*+*$'`
    if [ ! -z "$match" ]; then
        echo "$match"
        lineno=0
        hadmatch=1
    fi  
    if [ $hadmatch != 0 ]; then
        #echo "line $lineno: $line"

        if [ $lineno == 3 ]; then
            echo $line
        elif [ $lineno == 8 ]; then
            echo $line
        elif [ $lineno == 21 ]; then
            echo $line
        fi
        lineno=$lineno+1
    fi  
done

line STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: line: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
