Programming :: Using Grep And Regular Expression To Find Class References In C++ File?
May 28, 2010I'm trying to math all class references in a C++ file using grep with regular expression. I'm trying to know if a specific include is usuless or not, so I have to know if there is a refence in cpp. I wrote this RE that searches for a reference from class ABCZ, but unfortunately it isn't working as I espected:
grep -E '^[^(/*)(//)].*[^a-zA-Z]ABCZ[]*[*(<:;,{& ]'
^[^(/*)(//)] don't math comments in the begging of the line ( // or /* )
.* followed by any character
[code]....
Well, I can get patterns like this:
class Test: public ABCZ{
class Test: public ABCZ {
class Test : public ABCZ<T>

Programming :: Grep Not Getting Whole String?
Aug 23, 2010I am trying to monitor how long an ldap search takes and maybe notify or something that a search takes longer than say 10 seconds.
Code:

Programming :: Grep A String With Space?
Feb 9, 2010I am using Sun 5.9.
I am putting the value "Feb 10" in variable 'c' here.
Code:
-bash-3.00$ c=`date | awk '{print $2 " " $3}'`
-bash-3.00$ echo $c
Feb 10
But when I am grep-ing value of 'c', I am getting this error.
Code:
-bash-3.00$ ls -lrth | grep $c
grep: can't open 10
This is because there is a space between "Feb" and "10".
Programming :: Find And Replace A String In A File Using Perl Command From Bash Script?
Feb 14, 2011I wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.

Programming :: Find The Orphaned Images Using Grep
Jun 16, 2010I have inherited a wordpress theme with a folder of images that I think are no longer being used. I wanted to find the orphaned images using grep, so I wrote this script:
Code:
#!/bin/bash
echo $PWD
for i in *.*; do
cd ..
[Code].....
Its seems like I got some false positives out of it, but it worked pretty ok. I guess. :| Of course, it is not checking for images in the content of the database.
Orphan finding has to be a wheel that is already invented.

InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9

Jul 16, 2011I am using File::Find to go through a very large tree. I am looking for all xml files and open only those that contain a tag <Updated>. I then want to capture the contents of two tags <Old> and <New>.
My problem is, after I open the file and do the first grep for <Updated> (which does work), I am unable to grep again unless I close the file and open it.
I did something like this:

find(&check, $dir);
sub check {

Server :: Find A String In A File And Delete That Line As Well As X Lines After?
Jun 24, 2010I need to find a string in a file ... then delete the line it is on, as well as the next 6 lines. Or, delete the line the string is on and all subsequent lines until the search finds the character "["
