Data How to change a number on a specific lines in a file with shell?
Hello

My problem is that I want to change some specific numbers in a file. It is like,

Code:

The number I want to edit is the number after FBO which is the 11th column in the header string.
(Ex: 2009 10 5 0705 27.2 L 40.477 29.166 5.5 FRO 7 0.7 1.2LFRO 2.4CFRO 1.3LMAM1)

All I need is to add 1.3 to that number. The line number between the blank lines vary.

I create two file one with "FRO number" and one with "FRO number+1.3" And tried to replace them with sed command.

Code:
sed 's/12.8  FRO/14.1  FRO/g' file1 > file2

but since the values repeated several time it went all the way wrong so that idea of mine became useless.

Any help would be appreciated...

update-gap-workspace

UPDATE-GAP-WORKSPACE(1) 					   User Commands					   UPDATE-GAP-WORKSPACE(1)

NAME

       update-gap-workspace - manage a GAP workspace.

SYNOPSIS

       update-gap-workspace

       update-gap-workspace update

	      Create or update the GAP workspace.

       update-gap-workspace delete

	      Delete the GAP workspace.

DESCRIPTION

       At  start  up,  GAP  load  all  libraries and packages available on the system.	This take several seconds. To save time, GAP can store the
       result of this initialisation in a `workspace'.	update-gap-workspace help to manage such workspaces.  update-gap-workspace can be  run	as
       root  to  manage  the  system-wide  workspace.	update-gap-workspace  can be run as a normal user. In this case the workspace is stored in
       $HOME/gap/workspace.gz.

       Note that you need to rebuild the workspace each time GAP packages are added, removed or updated. To automate that task, if the system-wide
       workspace exists, it is automatically updated whenever a GAP-related Debian package is installed or upgraded.

       The gap script will automatically load such workspace at start up.

FILES

       /var/lib/gap/workspace.gz:
	      The system-wide GAP workspace.
       $HOME/gap/workspace.gz:
	      The user-specific GAP workspace.

SEE ALSO

       gap(1), The `SaveWorkspace' function in the GAP manual.

AUTHOR

       Bill Allombert <ballombe@debian.org>

NOTES

       We  are	considering  enabling the system-wide workspace per default, though this feature could be too confusing for old-time GAP users. If
       you have opinions about it, please mail <gap@packages.debian.org>.
