need help in cp command

deeptinegi · 10-10-2007, 06:04 PM

i was changing one dos command to linux command, its like:

copy c:\file.mdl c:\data\file_dd.m*

That is the file extension should be the same as the source file(we can have file.mdl, file.mdo..).In linux i did this

cp /folder1/file.mdl /folder/folder1/file_dd.md*
i am getting md* instead of the correct file extension.

Can anybody help me

i am just a beginer

This will work
cp /folder1/file.md? /folder/folder1/

or for anything with .md* extension even more than 3 chars

cp /folder1/file.md* /folder/folder1/

its because that copies file.mdl to /folderfolder/file_dd.md, I think you want cp /folder/file.md* /folder/folder1/ which copies any files in /folder with any extension beginning with md to /folder/folder1

Try this bash script, lets call it 'kacp' (kick ass copy):

Code:

#!/bin/bash

if [ $# -eq 0 ]; then
   echo "Usage: `basename $0` file.name"
   exit 0
fi 

filename=$1
ext=${filename##*.}
base=${filename%%.*}

echo
echo Copying file: /folder1/$1  to /folder1/"$base"_dd."$ext"

cp /folder1/$1 /folder1/"$base"_dd."$ext"

Then you should execute it as:

Code:

kacp file.mdl

You need to change source and destination paths in the script from 'folder1' to a real name. But you got the idea....
