Is that the output of a command or a record in a file?
You could use cut, or sed or awk.
Code:
echo '1.2M /root/Desktop/123rwewv.zip' | awk '{ print $1 }'
1.2M
echo '1.2M /root/Desktop/123rwewv.zip' | cut -d/ -f4
123rwewv.zip
These are just two possible solutions of many. By the way, please capitalize the word "I". It is rude to use IM speak in a forum entry. Thanks.
