Hi All,

I have Information in the file like,

============ Interface Information ====================
+++++++++++++++++ NMInterface ++++++++++++++
ObjID:251c55a2-2257-71dd-0f68-9887a1f10000

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,

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

#!/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

Anyother script or Solution that will help me?

5

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:

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.

#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?

The same way more than one record. There is no space line in between.

Try this (g|m|n)awk snippet:

BEGIN {RS="=+ Interface";OFS=FS="\n"}

$2 ~ / NMInterface /{
        print $5, $10, $23
}

Usage:
$ gawk -f test.awk file.to.parse

10

Getting this error:

# awk -f unman.awk aust00m1
awk: Cannot find or open file unman.awk.
The source line number is 1.
The error context is
>>> <<<
#

How to execute the gawk or awk. Pls. help me I will be very greaful to you.

Thanks,
Gobinathan.S

11

Try this:

$ awk 'BEGIN {RS="=+ Interface";OFS=FS="\n"} $2 ~ / NMInterface /{print $5,$10,$23}' your.file
12

Ripat,

The script is giving this error:

awk: Input line
([SrcNodeObjID, Sr cannot be longer than 3,000 bytes.
The input line number is 49. The file is aust00m1.
The source line number is 1.

It's trying for some other text patterns.

Thanks,
Gobinathan.S

13

Can you attach a bigger sample file that I could test?

14

I have attached the SAMPLE Input file here. Pls. give me the script for my req.

Thanks in Advance,
Gobinathan.S

Script is working flawlessly on my box although only one record is returned. I notice that you have a number of occurrences of:

----------------- NMInterface --------------
+++++++++++++++++ NMInterface ++++++++++++++

and not only

============ Interface Information ====================
+++++++++++++++++ NMInterface ++++++++++++++

Not the same record separator.

Which version of awk do you have?

$ awk --version

16

Yes, But my requirement is,

Whenever the string matches "+++++++++++++++++ NMInterface ++++++++++++++" then It should print upcoming line of 3rd line, 8th line and 21st line. (No need to consider the above line in any of the text pattern)

I already have same kind of script that will print Whenever the string matches "+++++++++++++++++ Interface ++++++++++++++" it's printing next 5 lines.
#!/bin/sh
awk ' $0 ~ /\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+Interface\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+/ {
match_str="YES"; line_cnt=0; next; }
{
if((line_cnt < 5) && ( match_str=="YES"))
{
print $0;
line_cnt += 1;
}
else {
match_str="NO"; line_cnt=0; }
}' <Input_File>

Pls. guide me now.
Thanks,
Gobinathan.S

Right. Try this:

$ awk 'BEGIN {RS="\++ NMInterface";OFS=FS="\n";ORS="\n\n"} {print $4,$9,$22}' your.file

But in that case the 21th line doesn't always return what you expect:

EntityName:aust00m1.mis.amat.com[ 0 [ 255 ] ]
OverallStatus:Normal
IfName:AT9/1/0.145

EntityName:aust00m1.mis.amat.com[ 0 [ 256 ] ]
OverallStatus:Normal
Capability: 

EntityName:aust00m1.mis.amat.com[ 0 [ 257 ] ]
OverallStatus:Normal
IfName:AT9/1/0.315

EntityName:aust00m1.mis.amat.com[ 0 [ 258 ] ]
OverallStatus:Normal
Capability: 

EntityName:aust00m1.mis.amat.com[ 0 [ 259 ] ]
OverallStatus:Normal
IfName:AT9/1/0.325

Still have the same pbl with awk?

18

Hi Ripat,

Thank you so much for your hard work on my requirement. I'm looking for an alternate way to achive my requirement. Because It's not giving proper info on 21st line.

I will get back on the forum after I find an alternate way to grep my info.

Thanks for your support, Thanks all

Gobinathan.S

Don't give up! If the 3rd info is not always on the 21st line, there is a work around. Try this:

#!/bin/bash 
awk '
BEGIN {RS="\++ NMInterface";OFS=FS="\n";ORS="\n\n"}
{match($0, /IfName:[^\n]+/, out);print $4,$9,out[0]}' your.file
20

Ripat,

How to run this file?

I'm using HP-UX 11.23

First I copied all those your commands to file 'int'
then executed,
Error:
# ./int
syntax error The source line is 3.
The error context is
{match($0, >>> /IfName:[^\n]+/, <<<
awk: The statement cannot be correctly parsed.
The source line is 3.

Then I changed to bash.
then executed,
ERROR:
# bash
# ./int
Segmentation fault (core dumped)

How to resolve this issue?

Thanks,
Gobinathan.S
