Hi All,

I have Information in the file like,

Requirement:

Whenever the string matches "+++++++++++++++++ NMInterface ++++++++++++++" then It should print followed of 3rd line, 8th line and 21st line.

Example result:

EntityName:aust00m1.mis.amat.com[ 0 [ 161 ] ] (3rd line)
OverallStatus:NotMon (8th line)
IfName:AT9/0/0 (21st line)


If anystring match again it should do the same operation.

Thanks in Advance,

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

I'm getting the following error:
./Interface.sh[3]: declare: not found.
./Interface.sh[4]: declare: not found.

Also, Tell me How to insert the Input file?

Thanks,
Gobinathan.S
# 4  
Anyother script or Solution that will help me?
# 5  
declare not found

Sorry, first line needs to be #!/bin/bash instead. of #!/bin/sh

/bin/sh is a link on my linux system to /bin/bash so I failed to notice I had put bash specific syntax in there.

Just pipe the input file into the script, like so

script < inputfile

Or if you want to pass it on the command line add something like this on the line immediately before the while like so:
Code:
cat $1 |
while read line; do

Which will cause it to read from the file passed as the first argument instead of from the standard input.

Error again

#Interface.sh < aust00m1
Memory fault(coredump)

I imagine that your file contains more than one "record". Is there a separation between records. Like a blank line?
