On (info "(coreutils) cut invocation") please add:
cut has no way to specify a group of blanks as a field demarcator.
If you want that, use perl -a. Also use perl's split if you want
regexp demarcators, etc.
If that is indeed the case.
Actually using tr from coreutils you can do:
tr -s '[:blank:]' '\t' | cut -f5
In fact I thought I had already added that to
the info docs. I had intended adding it at least,
but obviously I misremembered checking it in.
I'll do that very soon.
I'll push this to coreutils.texi (cut invocation) soon:
`-f FIELD-LIST'
`--fields=FIELD-LIST'
.............................................. Note `cut' does
not support specifying runs of whitespace as a delimiter, so to
achieve that common functionality one can pre-process with `tr'
like:
tr -s '[:blank:]' '\t' | cut -f...
cheers,
