Quick grep format question

Pamela J Goodwin — Wed, 14 Nov 2001 12:54:11 GMT

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

You can't do this with grep. If you have perl, try creating a script, say script.pl, containing:

while(<>) {
chomp;
foreach $word (split) {
if ($word=~/^[A-Z]+/) { print $word,"\n"; }
}
}

then run it:

perl script.pl yourfile > resultfile

resultfile will contain all words from yourfile starting with an uppercase letter, one word per line. If you want only all-uppercase words, add $ after + and if you want uppercase anywhere in the word, remove ^.

HTH,
Marcin

Hi,
here a solution without perl:

# cat bastel.sh
action()
{
while [ $# -gt 0 ]
do
echo $1 | grep -e '[A-Z]'
shift
done
}

while read LINE
do
action $LINE
done
#

echo inputfile | awk 'BEGIN { RS="[\ \t]"} { print $1 }' | grep [A-Z] > outputfile

short correction
---------------------------

echo inputfile | awk 'BEGIN { RS="[\ \t]"} { print $1 }' | grep ^[A-Z] > outputfile
