Do let us know your level of experience in shell scripting and what you've tried already by posting (pseudo) code.

yes.

It should be

# find /home -name '*.c' -delete
# find /home -name '*.text' -delete

Read the man page again.

and be very careful since you are deleting files as root. Don't yell if anything goes wrong.

Hi James, This will remove any files with the extensions c or text:
Code:
find /home/ -regex ".*\(text\|c\)$" -delete

pretty cool trick i loving linux
what if i want to do that in a script using rm command with multiple pattern
for example in the command prompt i type remove /home ".c" ".text" "~"
remove would be the name of my script so $1=/home, $2=the patterns
would this code work
for -d in $1 do
rm -regex ".$2"

Maybe something like this?
Code:
#!/bin/bash


        if [ $# -lt '1' ]; then
        echo -e "\n=> Listing files." && ls;
        echo -e "\nUSAGE: $0 + extensions to files you want to remove completely.\n"
fi

        if [ $# -eq '1' ]; then
        find -regex ".*\($1\)$" -delete
        echo -e "\nRemoving files with extension $1."
fi

        if [ $# -eq '2' ]; then
        find -regex ".*\($1\|$2\)$" -delete
        echo -e "\nRemoving files with extensions $1 and $2."
fi

        if [ $# -eq '3' ]; then
        find -regex ".*\($1\|$2\|$3\)$" -delete
        echo -e "\nRemoving files with extensions $1, $2 and $3."
fi
