Shell Programming and Scripting

Hi,

Can anyone help me parse the code bellow. I have a file with several lines. I ant to put an 'X' on the lines that ONLY have an '=' in them ignoring comma's, spaces etc..

So:
/*
,

systems.menuLabel.new=New
systems.menuLabel.new.mnemonic=N
*/

Would look like:
/*
,

systems.menuLabel.new=NewX
systems.menuLabel.new.mnemonic=NX
*/

Also if I have a line:
/*
systems.subsystems.servers=Name,Servers,Description,Work Servers available on the network
*/

I want it to come out like:
/*
Hi all and thanks. I used your code zaxxon and it worked fine.

I was wondering if I can change that now to use '=' sign instead of a commas?

So:
/*
,

systems.menuLabel.new=New
systems.menuLabel.new.mnemonic=N
*/

Would look like:
/*
,

systems.menuLabel.new=NewX
systems.menuLabel.new.mnemonic=NX
*/

Also if I have a line:
/*
systems.subsystems.servers=Name,Servers,Description,Work Servers
*/

to come out like:
/*
systems.subsystems.servers=NameX,ServersX,DescriptionX,Work ServersX
*/

Thank you!

nawk -f jas.awk myFile

jas.awk:

Code:

BEGIN {
  FS=OFS="="
  FSlist=","

  SUF="X"

  COMs="^[/][*]"
  COMe="^[*][/]"
}

$0 ~ COMs {comm++}
$0 ~ COMe {comm--}

comm && NF>=2 {
   n=split($2, valA, FSlist)
   for(i=1; i <=n; i++)
     $2=(i==1) ? valA[i] SUF : $2 FSlist valA[i] SUF
}
1

How can i run this?

bash: nawk: command not found is what I get

use either 'awk' or 'gawk' if available.

I used awk - thanks.

However it not seem to do anything, when I ran it it just printed out the text but there was no 'X' at the end of it.

given jas.txt:

Code:

/*
systems.subsystems.servers=Name,Servers,Description,Work Servers
*/

/*
,

systems.menuLabel.new=New
systems.menuLabel.new.mnemonic=N
*/

running:

Code:

nawk -f jas.awk jas.txt

produces:

Code:

/*
systems.subsystems.servers=NameX,ServersX,DescriptionX,Work ServersX
*/

/*
,

systems.menuLabel.new=NewX
systems.menuLabel.new.mnemonic=NX
*/

Is there anything wrong with the output?

Code:

sed -e '/=/s/,/X,/' -e '/=/s/$/X/' file_in

kiss...
