Say I have a line
blah.field
that needs to be commented out
//blah.field
which is referenced in a project in multiple files
Is there a way to comment this line in all places using a simple eclipse search and replace?
Replace regular expression:
^blah\.field$
with
//$0
^ = begin of line (here)
$ = end of line
$0 = the entire found match

/edit?o=U&show_mt=1&video_id=xxxxxxxxxxxx
I want get video_id query using regex (xxxxxxxxx)
I am using VB.NET
Thanks for help!
M. Deger
Edit: I want only regex code eg: [^?]+(?:\?video_id=([^&]+).*)?
Untested:
(?<=video_id\s*=\s*)[^&]*(?=&|$)
or, result in capture group 1
video_id\s*=\s*([^&]*)(?:&|$)

How would I parse
#extra_modules some string
in kdump.conf file to get "some string" as actual output in bash script ?
Thanks !
grep "#extra_modules" kdump.conf | cut -c 16-
grep finds the lines with the phrase "#extra_modules", and cut selects all the characters after the first space

I have the following line of XML:
<indexentry><secondaryie>definition, 3/2/4</secondaryie></indexentry>
And I need a regex that matches the above and converts it as below:
ABC3(the first number)/P-2(second number)-4(third number)
How can I do this?
Use this regex:
([0-9]+)/([0-9]+)/([0-9]+)
And from captured groups #1, #2, #3 make your string:
ABC3\1/P-2\2-4\3

I currently have this Regex:
.*[a-z]$|.*[A-Z]$|.*[0-9]$
I need to add the following to the existing - /:.#[]()
Does anyone know how to do it?
You don't need multiple OR conditions. Have only one and include special characters also:
[0-9A-Za-z\/#:.()\[\]]
Per your comments, this should do it for you:
^[a-zA-Z0-9/:.#\[\]()]+$
This will match a string containing only the characters you've specified.

I would like to find a word in a text file, and save it to a variable along with some characters. for example in the text file it would be something like:
Isoelectric Point = 6.2505
I'll be looping through a directory of files, so the value of the Isoelectric Point will change, and that is why I need the characters after the match to be saved to a variable.
if (my ($point) = $str =~ /Isoelectric Point = (\S+)/) {
...
}
