Programming :: Using Grep To Find EXACT MATCH?

Nov 11, 2010

I'm trying to find exact matches of some users in the /etc/passwd file using "grep -w", but it doesn't always work. For example, I have the following users:[URl].. So, let's say, I want to search for the user "stewart" (which doesn't exist)

Programming :: Match Datetime By The Minute (not An Exact Match By The Second)

Oct 21, 2010

I have the following query:

Code:
$sql="SELECT table1.datetime, table1.user_id, table2.ip, FROM table1,table2 WHERE id='$id' AND (table1.id = table2.id AND table1.datetime = table2.datetime)";

In table2 the datetime fields are about 1 to 2 seconds off due to the source of the data, which I cannot change.

Is it possible via a query match table1.datetime & table2.datetime by HH:MM (ie. to the minute instead of to the second)?

Programming :: Grep For Exact Number 0?

Aug 6, 2010

1) I need to search a field value to check for exact 0. If the number is 0, it should throw error.

The line to be searched looks like as below. "Output Rows [1], Affected Rows [1], Applied Rows [1], Rejected Rows [0]"

Here I have to search whether the affected rows is 0. But the code below picks up other values also (lie 10, 20.. etc). How do we write to get an exact match for 0? Code: affected=`echo ${line} | cut -f6 -d" " `

affectedcount='echo ${affected} |grep 0 ` 2) Also, I need to check whether the rejected rows > 0
Code: rejected=`echo ${line} | cut -f12 -d" " `
rejectedcount='echo {rejected} |grep [1-9]`

3)Can we combine these two statements in a better way to get the desired results?

Programming :: Exact Text Find And Replace?

Aug 13, 2010

I have a sysctl.conf that has the following in it:

kernel.exec-shield-randomize = 1
kernel.exec-shield = 1

When I grep kernel.exec-shield I get both line, hence I keep over writing the kernel.exec-shield-randomize in my script because it finds them both for my sed commend.

How can I get an exact match with either sed/awk/grep in shell so I can do a find and replace?

Example: sed 's/^kernel.exec-shield =.*/kernel.exec-shield = 1/g' /etc/sysctl.conf will replace BOTH lines

Example: grep "^kernel.exec-shield" find both line and I want it to find only the exact line.

Programming :: Find The Orphaned Images Using Grep

Jun 16, 2010

I 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.

General :: Get Files That Match ALL Patterns (using Grep)?

Jun 9, 2010

I want to traverse a directory and get a list of files that contain a set of patterns. I assumed I could use grep for this, but I having trouble getting grep to only return files that match ALL patterns. Here's what I've come up with so far:

Code:

grep --recursive --file=searchpatterns.txt --files-with-matches somedirectory/*

However, this gives me a list of files that match ANY of the patterns in the searchpatterns.txt file. I want to match ALL of the patterns. I've looked through the man page, but can't find anything that allows me to change the "OR" to "AND" for multiple patterns.

Programming :: Using Grep And Regular Expression To Find Class References In C++ File?

May 28, 2010

I'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

General :: Easy Way To Find Out Like Which Items Don't Match Between 2 Files Regardless Of Order

Mar 15, 2011

I have following 2 files

File1
10.1.1.1
10.1.2.1
10.1.3.1

File2
10.1.3.1
10.1.2.1
10.1.1.1

Both are reverse of each other. Now, basically if you see, the contents are same, but in different order. Is there any easy way in which i can find out like which items dont match between 2 files, regardless of order. Lets say i add 10.1.4.1 to File1. Now the result of such comparison should be only '10.1.4.1'. Currently if i am comparing both files using diff, it gives me all the lines.

General :: Using 'find' And 'grep' In A For Loop?

Mar 23, 2011

I have a server hosting 100+ websites. I need to quickly identify which websites are configured with a database. There are way too many to manually check every website for a PHP file with a database name. So, I created a list of all databases from MySQL and put them in a text file. I then exported the text file to a shell variable and used it in a for loop.

bash variable

Code:
DBLIST=`cat dblist.txt`
Example of $DBLIST

Code:
db1 db_testing2 database_clientname production words4cheap
for loop

Code:
for db in $DBLIST; do find . -type "f" -iname "*.php" -exec grep -i $db '{}' ; -print; done
Note: my find statement starts searching at . which is the directory that contains all of my websites and their data, each website is setup in a sub directory, identified by it's domain name.

Example: I'm in /var/www. Beneath /var/www are a list of directories:

[URL]

However, this is taking too long (it's been running most of the day) and I was wondering if there wasn't an easier way to accomplish what I'm trying to achieve?

General :: Searching For PHP Files With Find And Grep

I am looking for all the files that contain the text string 'moo.sql'. I ran the following:

Unfortunately it seems to return non-php files in addition to php files. I thought the find portion of this would filter the file names so grep would only search php files.
