You have gotten three different suggestions so far.
1. Use xargs
ls | grep -i '\.zip$' | xargs rm
2. Use find with -exec
find . -iname \*.zip -exec 'rm {]' \;
3. Use process substitution.
for i in $(find -iname "*.zip"); do rm $i; done;
Always, wait, should I say that again in reverse, blinking underlined
text?, *ALWAYS* use form 1.
If you don't understand it, read the man page. Use it. Love it.
Use of 1 will run one skinny process.
2. will execute a seperate process for *EACH* file to be deleted.
3. will execute a seperate process for *EACH* file to be deleted and would
potentially overflow before the for loop even starts.
