Is there some way to specify a field delimiter for a space or more (like " "+) ?
For example: In the following string, I like to reach value '30695' what field delimiter I should say? Thank you.

I appreciate your response very much. Actually, my example string has one or MORE spaces but when it showed up on this page, it squezzes 2+ spaces into 1 space. In addition, I tried to use 'cut' command to get the size value of files from the output of 'ls -ltr' command.
Ex. ls -ltr | cut -d" " -f5 . This command will work if there is only one space separated between fields. And it won't work in my string because it has either one or more spaces between fields. Any idea ? Thanks.
