I’m teaching myself perl on the fly, and I can’t find any good documentation on regular expressions and delimiters that don’t involve "Hello World."
Can you help me decipher what this expression is doing?
if (/^WAIT #(\d+): nam=’([^']*)’ ela=\s*(\d+)/i)
the input is a oracle trace file, and this line is looking for lines anchored with WAIT. But I’m not following the rest of the line
is there a way to make WAIT = ?
This line is from the classic formmail.cgi script:
$value =~ s/~!/ ~!/g;
It’s to stop people from using subshells. But, does anyone know what this line is actually doing and how it’s doing it?
Thanks.
I am trying to read all latitude and longitude values from NWS warning files like this: http://www.weather.gov/data/SGF/SVRSGF
The latitude/longitude values always appear at the bottom of the warning, between "LON" and "TIME". I had been using the regular expression: $stwarn =~ m/LON(.*)\nTIME/ but it doesn’t seem to work for all warnings.
Can anyone offer any better suggestions? Thanks!
Record Line:
1,2,3,"four,for",5,"six,ssiixx","seven"
I want to remove the comma in "four,for" and "six,ssiixx". I tried using the $myValue =~ s/<regular_exp>/<replace_value>/g but I just end up replacing the string starting from the bad field to the last instance of a comma on the record.
Yahoo cut off my record string. Here it is again:
1,2,3,"four,for",5,"six,ssiixx","seven"
Once again, here is the full string with comma plus spacing afterwards:
1, 2, 3, "four, for", 5, "six, ssiixx", "seven"
I’m satisfied with raymanrevo’s answer but how do I choose "Best Answer"?
Here is a modified version of raymanrevo’s suggestion incorporating possible spacing:
$myValue =~ s/("[\w\ ]*),([\w\ ]*")//g;
Thank you raymanrevo!
