工作学习 / IT技术讨论 / Help: Unix expert , please coming about regular expression!! -smpp(流浪ing); 2003-4-10 {589} (#1133829@0)

/^3\d*/ or simply /^3\d\d\d\d\d\d\d\d\d\d$/ -redmouthbird(你个老胖弟); 2003-4-10 (#1133883@0)

should that be grep "3[0-9]{10}" test ? -guestagain(guest again); 2003-4-10 (#1133915@0)

which OS do you have, I got Solaris 8.0?actually, my scenario is very simple , match a digital string with this pattern, and if match this range, then pass this string to next. otherwise reject.
the problem is : the vendor of this application did not give the fully document of this , just tell me use the unix expression , it will work.
I will try it again

thanks -smpp(流浪ing); 2003-4-11 {330} (#1136153@0)

regexp is always the same. It has nothing to do with the OS. In your case, I beleive you need more support from the application vendor. -pasu(InTheSky); 2003-4-11 (#1136156@0)

Although there's something called POSIX regular expression, it varies slightly from program to program. The most popular ones are sed, grep and perl, here's how...grep: takes one line at a time. "grep '3[0-9]\{10\}' <filename>"
sed: takes one line at a time. "sed -n '/3[0-9]\{10\}/p' <filename>"
perl:
open(IN, "<filename>") or die("cannot open <filename>");
whiel(<IN>) {
if($_=~/3\d{10}/) {
print;
}
}

Try this one egrep "^3[0-9]{10} | 3[0-9]{10} | 3[0-9]{10}$". 注意，| 前后是space -demijohn(老三); 2003-4-10 (#1134424@0)
space 也算是字符，若要找以3开头的数字，必须考虑3之前有space 或以3开头的行。grep "3[0-9]{10}” 凡是有3dddddddddd 的字符串都会符合，如23dddddddddd 也符合，所以不对。 -demijohn(老三); 2003-4-10 (#1134453@0)
