Shell Programming and Scripting

Hello Friends,

i need help to remove "#" sign from a file. I want to remove the "#" marks just in the area mentioned in red. I am not so good in awk, this help would be deeply appreciated.

thanks
Ado



trap = {
# {
# trap-community = SNMP-trap
# hosts = hubble, snowbell
# {
# enterprise = "sun"
# trap-num = 0, 1, 2-5, 6-16
# }
# {
# enterprise = "3Com"
# trap-num = 4
# }
# {
# enterprise = "snmp"
# trap-num = 0, 2, 5
# }
# }
# {
# trap-community = jerry-trap
# hosts = jerry, nanak, hubble
# {
# enterprise = "sun"3
# trap-num = 1, 3
# }
# {
# enterprise = "snmp"
# trap-num = 1-3
# }
# }
#}




Output should be like

trap = {
{
trap-community = SNMP-trap
hosts = hubble, snowbell
{
enterprise = "sun"
trap-num = 0, 1, 2-5, 6-16
}
# {
# enterprise = "3Com"
# trap-num = 4
# }
# {
# enterprise = "snmp"
# trap-num = 0, 2, 5
# }
}
# {
# trap-community = jerry-trap
# hosts = jerry, nanak, hubble
# {
# enterprise = "sun"3
# trap-num = 1, 3
# }
# {
# enterprise = "snmp"
# trap-num = 1-3
# }
# }
}

sed -e 's/^# //' file_in > file_out

this did not work, i just want to remove the # marks from the red area, not from the whole file.

While I can see what you put in red, what is the rule to know what to remove the # character?
For instance,
lines 1-10, 20, 30
or
???

I think to remove by line number(NR) would be okay. i just want to get the file to look like as i mentioned in the output.

thanks

just a dumb question:

how do you know . ... which lines you want commented out?

apparantly you need this done during a batch program, that'll be
run many times, otherwise, just use vi and edit the thing....

If you know which lines need to be commented out based on
some criteria, then this is a rather difficult approach.

Can you do something like:

Code:

case $condition in

  A) this_trap_stuff ;;
  B) that_trap_stuff ;;
  C) even_more_other_trap_stuff ;;

esac

script execution

Code:

> play162.sh
trap = {
 {
 trap-community = SNMP-trap
 hosts = hubble, snowbell
 {
 enterprise = "sun"
 trap-num = 0, 1, 2-5, 6-16
 } 
# {
# enterprise = "3Com"
# trap-num = 4
# }
# {
# enterprise = "snmp"
# trap-num = 0, 2, 5
# }
 }
# {
# trap-community = jerry-trap
# hosts = jerry, nanak, hubble
# {
# enterprise = "sun"3
# trap-num = 1, 3
# }
# {
# enterprise = "snmp"
# trap-num = 1-3
# }
# }
}

script

Code:

> cat play162.sh

awk '
  { if (((NR>=2)&&(NR<=8)) ||
  (NR==17) || (NR==30)) {
    print substr($0,2,99)
  } else {
    print 
  }

}' file162
