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 302366656 by Teroc on Friday 30th of October 2009 04:53:25 AM

I doesn't work GhostDog, well it probably does, but not in my case.
I did something like that:

Code:
NR==FNR {a[$2]=$1;next} #I read a first file to get the search pattern
{if ($3 in a)
    {$3=a[$3]
    print
    d=9
    next}
    d--&&d>=0
}

But it does only print the first line.

Here is an example of my files.
The first file where I read the values looks like this:
Code:
a1 b1
a2 b2
a3 b3

Then the second file looks like: (there is also other stuff in the file not related)
Code:
....
/begin MEASUREMENT b1
   "comment" 
   UWORD 
   ident 
   1 
   100
   0 
   65535 
   ECU_ADDRESS 0x4000582C
  /end MEASUREMENT 
....

I want to check if $3==b1, then replace it with a1 and copy the others lines at the end of the file, and do it for each bi of the first file.

thanks for your help.

Found a solution doing this:

Code:
NR==FNR {a[$2]=$1;next}
{if ($3 in a)
    {$3=a[$3]
    print
    d=9
    while (d>0)
    {getline; print; d--}
    }
}

size

SIZE(1) 						      General Commands Manual							   SIZE(1)

NAME

       size - print the size of the sections in an object file

SYNOPSIS

       size [ option ... ] [ object ... ]

DESCRIPTION

       Size  (without  the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments.	All other segments
       are totaled and that size is listed in the `others' column.  The final two columns is the sum in decimal and hexadecimal.  If  no  file	is
       specified, a.out is used.

       The options to size(1) are:

       -      Treat the remaining arguments as name of object files not options to size(1).

       -m     Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of
	      the segments in the file.

       -l     When used with the -m option, also print the addresses and offsets of the sections and segments.

       -x     When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal.

       -arch arch_type
	      Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a universal file.	(See  arch(3)  for
	      the  currently know arch_types.)	The arch_type can be "all" to operate on all architectures in the file.  The default is to display
	      only the host architecture, if the file contains it; otherwise, all architectures in the file are shown.

SEE ALSO

       otool(1)

BUGS

       The size of common symbols can't be reflected in any of the numbers for relocatable object files.
