multiple spaces between columns with grep

multiple spaces between columns with grep

Hi all,

On AIX I had some problems with \s+ matching spaces so ended up using [[:blank:]]. But if there are multiple spaces between two words in a file, what is the best way of using [[:blank:]] without typing it more than once? Also the number of space varies per line, so there is no fixed number of spaces.

Any ideas?

Many thanks


RE: multiple spaces between columns with grep


Just add the + quantifier after that too : [[:blank:]]+.

By the way, \s's corresponding POSIX character class is actually [[:space:]].
