Capitalize the first letter of a variable only: Kshell

[Teebu Philip]

how in the world do i do this ?

i have tried using sed with "y" as follows:

fname="fwdBldCall"
nfw=`echo $fname | sed "y/[a-z]/[A-Z]/"`
echo "fname = $fname"
echo "nfw = $nfw"

this is what i get:
philip@thunder 267% fname="fwdBldCall"
philip@thunder 268% nfw=`echo $fname | sed "y/[a-z]/[A-Z]/"`
philip@thunder 269% echo $fname
fwdBldCall
philip@thunder 270% echo $nfw
fwdBldCAll

What am I doing wrong ?

Thanks in advance!

sed doesn't work like tr - you need to explicitely state the entire
alphabet in both instances. but that won't help you change only the
first character. The way you have it set out, the entire variable will
be converted. You need:
nfw=`echo $fname | sed '/./
y/qwertyuiopasdfghjklzxcvbnm/QWERTYUIOPASDFGHJKLZXCVBNM/'

Notice the /./ at the beginning of the sed. In Korn shell you could do
this:
typeset -uL1 c=$fname
nfw=$c${fname#?}
which would be faster than sed.

»sed« is overkill here. What about just using »tr«?

nfw=`echo $fname | tr a-z A-Z`

or

nfw=`echo $fname | tr [:lower:] [:upper:]`

In article <Pine.SOL.3.91.101050...@godzilla6.acpub.duke.edu>,

You are using sed unnecessarily and incorrectly. I'll leave it to a
seder to correct your sed usage, but capitalizing the first char
of a variable is easy in ksh.

$ x=abcdef
$ typeset -uL1 f=$x
$ print "${f}${x#?}"
Abcdef

the typeset command creates a special variable that is uppercase,
Left aligned and one char long. ${vname#pattern} trims the first
occurrance of pattern from the start of $vname. '?' matches a single
character.

${x#?} trims the first char from $x and returns the resulting string

tr capitilizes all the letters ... i just want the first one to
be capitilized

philip@thunder 383% echo $fname | tr a-z A-Z

Oops, sorry. I should better go to bed. ;)
Forget my last posting and use the other internal ksh suggestions.
