Shell Programming and Scripting

thank a lot guys your answers helped me but now i have one more problem

i want to append to the end of a line that starts with a specific character and this line can have any character and spaces in it

soft of like this:

Code:

         this is a line
      -  this line starts with a minus
      + this line starts with a plus
         this is another line

and i want to be able to append //foo to the end of that line:

Code:

         this is a line
      -  this line starts with a minus //foo
      + this line starts with a plus //foo
         this is another line

how can I do that i've been trying to adapt the solutions that you guys posted for mi first post but so far I haven't been able to make it work

Thank you for you help.

awk or sed?

Code:

awk '$1~"^[+-]"{$0=$0 " //foo"}1' infile

Code:

sed '/^[ \t]*[+-]/s|$| //foo|' infile

thanks a lot you guys you solved all my problems

Code:

sed ' /^[[:upper:]]\+$/  s/$/]FOO/' filename

note:
\+ is a GNU sed extension and this will not work with other seds..
