For developers .Ve .SH "EXPRESSIONS" .IX Header "EXPRESSIONS" \&\fBnumgrep\fR uses a special numeric expression matching system. Basically, it searches for ranges, factors and sequences of numbers. Here is a list of the syntax characters and some sample expressions that will get you going: .PP .Vb 3 \& // \& Put your expression or set of expressions between these \& two forward slashes. \& \& .. Range expression. A number must be used on the left \& and/or right of this expression to specify that numbers \& between, greater than or less than the numbers specified \& should be matched. \& \& , Expression separator. The comma separates one complete \& expression from another in a set enclosed by //. \& \& m Multiples of . This operator, followed by a number \& will match any number that is an integer \& multiple of . Meaning that = times , \& where is any integer. \& \& f Factors of . This operator, followed by a number \& will match any number that is an integer factor of \& . Meaning that = divided by , where \& is any integer. .Ve .PP \&\fB \s-1NOTE:\s0\fR Checking for factors and multiples is very fast because it is checked by doing a single modulus operation on two numbers. .PP \&\fBExamples:\fR .PP .Vb 1 \& /2..10/ Match any number between 2 and 10. \& \& /2..10,20..30/ Match any number between 2 and 10 or between 20 and 30. \& \& /56,34,512,45,67/ Match any of the numbers 56, 34, 512, 45 or 67. \& \& /m3/ Match any integer that is a multiple of 3. \& \& /f1024/ Match any integer that is a factor of 1024. \& \& \& $ numrange \-N /1..1000/ | numgrep /f1024/ \& 1 \& 2 \& 4 \& 8 \& 16 \& 32 \& 64 \& 128 \& 256 \& 512 \& $ .Ve .SH "BUGS" .IX Header "BUGS" \&\fBnumgrep\fR can't handle certain situations properly. Such as if it encounters a number with leading zeros, it will treat it as an octal number and thus might not match the way you would expect. .PP \&\fBnumgrep\fR does not yet allow you to mix numbers and text in the matching expression. So you can not do something like \&'numgrep /port=0..1023/ firewall.log'.
