comment and Uncomment single task out of multiple task

Shell Programming and Scripting
1

I have a file contains

TASK gsnmpproxy {
CommandLine = $SMCHOME/bin/gsnmpProxy.exe
}

TASK gsnmpdbgui {
CommandLine = $SMCHOME/bin/gsnmpdbgui.exe

I would like to comment and than uncomment specific task eg TASK gsnmpproxy

Pls suggest how to do in shell script

2

Use a # at starting of line which is to commented with in the script.

e.g.

#!/bin/bash
# mycommand
command1

in this script the command line mycommand will not get executed...

and to uncommant remove # from there.

3

My intention is that what is the command if I run it will comment and uncomment the line

4

or Please suggest if the file contains a line snmpd so how to comment and uncomment the snmpd in the file by running the in the command prompt in shell.

If you want to comment the "TASK gsnmpproxy" you can something like:

awk '/TASK gsnmpproxy/{f=1} f{$0="#"$0} /\}/&&f{f=0} 1' file

suppose test is the file name and you want to comment line having gsnmpproxy

grep gsnmpproxy test| sed -ie 's/ ^/#/g'

When I run this command from other server through ssh ...ssh is workinf fine..here X,Y,Z is used for ssh

${X} -l ${Y} ${Z} "trap '' INT;. ~/.profile >/dev/null 2>/dev/null; awk '/TASK gsnmpproxy/{f=1} f{$0="#"$0} /\}/&&f{f=0} 1' filename"

it gives error like

awk: syntax error near line 1
awk: bailing out near line 1

So please suggest above one or please write how to comment a line in a file if the that line is INDIA.

Useless use of grep, sed can grep for you.

@madhusmita
man sed to see if your sed support -i switch

sed -i '/TASK gsnmpproxy/s/^/#/' test

Use nawk or /usr/xpg4/bin/awk on Solaris.
