Shell Programming and Scripting

Hi folks,

What I have are config files with lines that: are blank, start with a "!" or start with char's(or a blank space and then char's)

I am using ksh

I can display each line by doing:

Code:

for INDEX in {0..$LENGTH}
do
   echo "${data[$INDEX]}" 
done

What I need to do requires I can separate the lines into the three classes
the psudo code looks like this:

Code:

for INDEX in {0..$LENGTH}
do
 -psudoCode
  If echo ^{${data[$INDEX]}"} = "  "  # note: two blanks in quotes
    then
      If echo ^{${data[$INDEX]}"} = "!"
        then
          do something
        else
          do something else
     fi
  fi
 -end psudoCode
done

Now, I know I can do this using if and regex, but have tried many ways...and searched the web for answers to try. I can't seem to crack this and am hoping someone can help

Thanks!

awk is inherently able to deal with this.
please give us sample input and expected output.

What we have so far is interesting but not on the path to helping you.

Expected output after first processing will take the first of actual config line after a "!" as a heading and provide a menu.
So from above, the first run through the $data[$INDEX] array would provide:

"Menu of options:

1 version
2 Hostname
3 boot
4 logging"

Then, after capturing the data for a menu, I want to be able to select a number and get the block corresponding to that heading

Ex:
if I hit "2" and enter
I get:

hostname MarcsTestbox

if I hit "4" and enter
I get:

logging message-counter syslog
enable secret {FIELD DELETED] [FIELD DELETED]


Thanks for helping!

Please repost your sample input using code tags. Since you've used the circumflex character in your pseudocode, I'm assuming that you're looking for some lines starting with two space characters; but none of the lines in your sample input have any leading space characters.
Please ignore this posting. When I first read message #3 in this thread, I was trying to make sense of it given the pseudocode in message #1. I now realize that message #1 can be ignored and the full specification of what you want is in message #3.

On top,I'd be surprised if your snippet for INDEX in {0..$LENGTH} would work...

Rudi,
In recent versions of ksh:

Code:

x=4
for i in {0..$x}
do echo $i
done

produces:

Code:

0
1
2
