Full Discussion: Help with a shell script to modify one line and copy the next 9 to same file
Top Forums Shell Programming and Scripting Help with a shell script to modify one line and copy the next 9 to same file Post 302366724 by Teroc on Friday 30th of October 2009 07:38:03 AM

I have another problem related to those files.

Sometimes, in file1, it is possible that one value in column 1 is associated to 2 or more values like this:
Code:
a1 b1 c1
a2 b2
a3 b3 c3 d4

Now, when I need to replace and copy as described in my other post, I need to do this for each value associated with a1.
The problem is, I tried with multidimensional arrays and other stuffs, but it doesn't write the full 9 lines for the 2nd value (c1 or c3).

Is there a way to jump back 10 lines up and retest the same line so I can process it again for the 2nd and 3rd value? I've searched since last post and can't find somethinbg working...

Thanks again and again !

Here is the code I use ...
Code:
NR==FNR {for(i=2;i<=NF;i+=1) a[$1]=$i" "a[$1];next}
NR!=FNR {print $0}

{if ($3 in a && $2=="MEASUREMENT")
	{temp=$3;
	split(a[$3],separate)
	for (x in separate)
	{$3=separate[x];
	buffer[j]=$0;
	$3=temp;
	d=9;
	while (d>0) #not printing for the second value of separate because of this while I guess, once it is done once, it wont do it again for the other values
	{getline; buffer[j]=buffer[j]"\n"$0; d--}  #I use a buffer so that I can write the thing where I want
	}j++
	}
}

And here is the ouput I have

Code:
...
/begin MEASUREMENT b1  #As intended
   "comment" 
   SWORD 
   ratio_0p1 
   1 
   100
   -2000.0 
   2000.0 
   ECU_ADDRESS 0x500040B4
  /end MEASUREMENT 
/end MEASUREMENT c1 #writes c1 here instead of the whole thing

virt-copy-out

virt-copy-out(1)					      Virtualization Support						  virt-copy-out(1)

NAME

       virt-copy-out - Copy files and directories out of a virtual machine disk image.

SYNOPSIS

	virt-copy-out -a disk.img /file|dir [/file|dir ...] localdir

	virt-copy-out -d domain /file|dir [/file|dir ...] localdir

DESCRIPTION

       "virt-copy-out" copies files and directories out of a virtual machine disk image or named libvirt domain.

       You can give one of more filenames and directories on the command line.	Directories are copied out recursively.

EXAMPLES

       Download the home directories from a virtual machine:

	mkdir homes
	virt-copy-out -d MyGuest /home homes

JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH

       This command is just a simple shell script wrapper around the guestfish(1) "copy-out" command.  For anything more complex than a trivial
       copy, you are probably better off using guestfish directly.

OPTIONS

       Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-in(1), virt-edit(1), virt-tar-in(1), virt-tar-out(1), http://libguestfs.org/.
