I have a file that looks like this:

BobMenefee

I want it to look like this:

Bob Menefee
_____________________________________________
My input file is called caps
I enter the following command:

sed s/'[A-Z]'/' [a-z]'/g caps

and I get
[a-z]ob [a-z]enefee

Any ideas how to do this ?

[Martin Johnson]

It is not a good idea to have spaces (or tabs) in you file names. Spaces/tabs have special meaning in the unix shells. You will have all sorts of problems trying to access the file.

file name is called 'caps'

the data in the file is 'BobMenefee'

I want to use sed to change it to Bob Menefee.

To put a blank before EVERY capital letter:

sed -e "s/\([A-Z]\)/ &/g" caps

Tom,

Thanks,

I've only been trying this for about 2 hours. It took you 2 seconds. I hate people like you.......just kidding.

Thanks a heck of a lot.

I suggest that you takes Tom's solution and then pipe it through another sed to get rid of the leading space.

sed -e 's/\([A-Z]\)/ &/g' caps | sed -e 's/^ //'

Hi

I thibk you cannot subsitute for the whole set it slef bcoz the logic will fail when it seraches for what to put ?

may be you can try for each and then run the whole 26 times like this

sed s/'A'/a/g
sed s/'B'/b/g
sed s/'C'/c/g
and so on
and then run this on the cpas file

perl solution, do not add blanks if a blank is already there:

perl -n -e '{s/([^ ])([A-Z])/$1 $2/;print}' caps

[Tom Maloy]

forgot the global flag...

perl -n -e '{s/([^ ])([A-Z])/$1 $2/g;print}' caps

need more caffeine...

[H.Merijn Brand (procura]

Only add a space before a capital that currently has a lower case letter in front:

# perl -pi -e 's/([a-z])([A-Z])/$1 $2/g' data_file
