Regex Question

Shell Programming and Scripting
1

Hi I am trying to match lines having following string

BIND dn="uid=

putting something like this is not working :

/\sBIND dn="uid=/

Any suggestion.

Thanks. John

You are putting it where? What language/tool?

3

I am using this within a perl script.

Try without "\s":

/BIND dn="uid=/

These are are a couple of examples:

$ cat t
BIND dn="uid=

** Perl example
$ perl -ne '/BIND dn=\"uid=/ && print' t
BIND dn="uid=

** sed example
$ sed -n '/BIND dn\="uid\=/p' t
BIND dn="uid=

Thank you, i have got it.

With awk

echo 'BIND dn="uid=' | awk '/BIND dn="uid=/'
BIND dn="uid=

A comment regarding the \s :
an anchor like ^BIND or \bBIND ensures it won't match WINBIND.

Actually "\s" is not an anchor. It is character class containing space and tab.

And more. It also matches \n , \f and \r . And this is with ASCII. With some locales/Unicode, this shortcut may match many more characters.
