Regular Expression Question

[gab10]

I'm not too good with Regular Expressions... does anyone know the syntax to find all the strings that don't contain a particular phrase? I tried
(somephrase){0}
but that doesn't seem to work.

This should work.


[^somephrase]+

This should work.
[^somephrase]+
Wouldn't that would equal[bcdfgijklnqtuvwxyz]+which would match lines that have at least one character not in 'somephrase'?


I dont know of a way to match not 'somephrase' with standard regexes. It depends on what app you're using.

Grep: grep -Gv "somephrase" filename

Perl script:
while (<FILE>) {
if ($_ !~ /somephrase/ ) { print "$_" }
}

Sed seems to have ! as negation operator, but I don't know how to use that.
