Krrishv, I was running this under Linux.
I didn't know the behavior of sed varied that much between different flavors, but I guess you're right:

I just tried my command on a FreeBSD box and it did not work. Smilie

It looks like \U is a GNU extension:
sed, a stream editor

Any other suggestions?

Code:
perl -pe 's/(.)/\U\1/'

I don't understand why shamrock's awk solution would not work, though. Are you sure?

And I don't uderstand either why the sed solution doesn't work. In addition, for words like anglo-american or o'brian try this:

Code:
echo 'anglo-american' | sed  's/\(^.\|[-\\''].\)/\U\1/g'

The \U thing is a relatively recent, non-standard extension to sed. (Actually it's relatively new in Perl, too; I recall it was only added in version 5.something.) This guy is on HP-UX, which I understand basically means they stopped adding features in 1979.

A ksh solution that requires no plugin...

Code:
$ cat up1
#! /usr/bin/ksh
typeset -L1 -u first
read word
first=$word
echo ${first}${word#?}
exit 0
$
$
$ echo hello | ./up1
Hello
$

On Solaris (see first post ) nawk or /usr/xpg4/bin/awk would have yielded the desired result. The default awk is old awk.

On sed (assuming the \U is avaiable ) also:
Code:
sed 's/./\U&/'
