Shell Programming and Scripting

I want to write a shell script to copy a list of files from one directory to another. And while copying it should change the first character of the filename to uppercase and others to lowercase.Below is what i have tried so far.

Code:

for file in "$@"
do
  if [ -f $file ]
  then
    ufile=`echo $file | sed -e 's/^./\U&/'`
    cp -v $file $ufile
done

With this code i am able to copy files only within the current directory and the whole filename becomes uppercase.
So how do i copy the files to other directory and how do i make the other alphabets in lowercase.

Can anybody help me out to complete the shell script???

I see your code is good except you are missing a fi

Code:

for file in "$@"
do
  if [ -f $file ]
  then
    ufile=`echo $file | sed -e 's/^./\U&/'`
    cp -v $file $ufile
  fi
done

BTW if you want to copy files to other directories you can append absolute path of destination directory as suffix to variable $ufile.

If you do not have GNU sed then try using awk instead:

Code:

echo $file | awk '{sub(/./, toupper(substr($0,1,1)));}1'

For any issues set xtrace and verbose and post the results:

Code:

/bin/ksh -xv

In bash, you could use "parameter case modification" - no need to resort to sed or awk

Code:

$ for f in file*; do echo $f"  "${f^}; done
file      File
file~     File~
file1     File1
file1~    File1~

I think the requester's system is running on HP-UX and case modification requires BASH version >= 4

Ouch - didn't notice the hp- logo in his header when looking for her/him mentioning system details.

Hi guys. thanks for the reply.
Bt i m a total beginner. I do no know what you mean by "xtrace".
also abt the absolute pathname, i want the script to take input from the user i.e the file to be copied and the destination.
And abt the case,i managed to make the first letter to uppercase bt wat abt the others which have to be in lowercase
