Hi,

I have files with all its characters in lower cases. I need to change them to "proper case" (starting char to be come Upper case). How can I? Pls suggest.

for e.g. xyz.txt should become Xyz.txt

TIA

With zsh:

zsh 4.3.4% touch xyz.txt abc.txt
zsh 4.3.4% autoload -U zmv
zsh 4.3.4% zmv '(*).(*)' '${(C)1}.$2' 
zsh 4.3.4% ls
Abc.txt  Xyz.txt

if you can use Python:

# echo "abc.txt" | python -c "print raw_input().capitalize()"
Abc.txt

Thanks ghostdog74 & radoulov.

I'm allowed to use bash/ksh/sh only.

echo "abc.txt" | awk 'BEGIN{OFS=FS=""}{$1=toupper($1);print}'

Hi Ghostdog,

I am getting abc.txt as it as but Abc.txt was expected.

#echo "abc.txt" | awk 'BEGIN{OFS=FS=""}{$1=toupper($1);print}'

abc.txt
#

Thanks

Hi Ghostdog,

I installed gawk 3.1.5 and your solution worked great.

Thanks much

In straight shell

filename=abc.txt
typeset -u first=$(expr substr $filename 1 1)
mv $filename $first$(expr substr $filename 2 ${#filename})
