Quick grep format question

[Pamela J Goodwin]

All - I need some help.

I want to use grep to copy all the words in a file which have uppercase letters into another file.

I just want the uppercase words themselves, not the entire line.

Can someone give me the command?

I'd appreciate it.

Thanks !

Hi Pamela,

If you want each word on a separate line:

for word in `cat {filename}`;do
echo $word | grep [A-Z]
done

Hi,

here a little correction:

for word in `cat `
do
echo $word | grep '[[:upper:]]'
done > newfile

Hi Pamela:

I'll add one new twist, too. I'm going to assume words might have upper and lower case letters just like in a sentence. I will assume too that you want only those words where ALL letters appear in uppercase and that they may appear with a trailing comma or period. Thus:

for WORD in `cat myfile`
do
echo $WORD||grep '^[A-Z,.]*$'
done > mynewfile

Regards!
