mutually exclusive patterns

[phife757]

Hi all,

how do you match patterns in an "if-else" fashion?

for example, say I have a set of patterns to match:

/foo/ { print "foo" }
/bar/ { print "bar" }
/.*/ { print "default" }

so for input file:

foo
bar
raboof

I'm getting:

foo
default
bar
default
default

but i would like:

foo
bar
default


Notice the lines "foo" and "bar" match twice. I would like the last pattern to match, only of the other patterns do not match. Does anyone have a solution to this?

Hi

/foo/ { print "foo"[red]; next[/red] }
/bar/ { print "bar"[red]; next[/red] }
/.*/  { print "default" }

[gray]# or[/gray]

/foo/ { print "foo" }
/bar/ { print "bar" }
[red]![/red]/[red](foo|bar)[/red]/  { print "default" }'

[gray]# or[/gray]

/foo/ { print "foo" }
/bar/ { print "bar" }
[red]![/red]/[red]foo[/red]/ [red]&&[/red] [red]![/red]/[red]bar[/red]/  { print "default" }
