help needed in BASH scripting

[neoknight]

Hi All,

I am planning to delete few files from a subdirectory, my aim is to locate all *.des files, remove them all except the one which the user specifies.here is the code i wrote which is not coming out right. des1 is already existing in the folder, and i am copying that to a new file with a different name and deleting all the *.des files in that folder.

one more thing is, that there are also other type of files in the directory. so i just want to remove only the *.des files keeping the only one which the user specifies.

#!/bin/bash
echo "Enter Des File name"
read des1
echo " Enter the 5 digit name"
read des2
cp $des1 $des2
touch $des2
for i in `ls .`
rm -f $i/*.des

i know that above code removes all *.des files, wat command do i add to exclude that particular user given file.

if you point me to the command name , i will figure out the code...

Thanks

You can just use a simple if statement to check that i isn't equal to the given file.

On another note you could also make your program cleaner and easier to understand by searching for .des files like so:

for i in `ls *.des`

Which would mean you can delete the file by:

rm -f $i

This will also make your if statement cleaner and easier to code. Good luck!

You could try something like this:

#!/bin/bash 

read -p'Enter des file name to preserve: '

shopt -s extglob

rm --  */!("${REPLY%.des}").des

Try the script with echo/printf instead of rm to verify the correct globbing.

Thanks guys..i did try this one and it worked..

find .not -name $des1 -iname "*.des" -exec rm -f {} \;
