OpenSUSE :: Grep And Recursive -r Not Working?
Aug 9, 2010works fine on a FAT32 dsk:
Code:
fgrep -iRn -C 2 'print' *.txt
---also recurses one level and displays all kinds of data
---------------------------------------------------------------
in root / ext4 directory:
Code:
fgrep -iRn -C 2 'print' *.* or fgrep -iRn -C 2 'print' *.txt
---displays msgs:
fgrep: *.*: No such file or directory
and
fgrep: *.txt: No such file or directory
I am probably missing something very basic.recursive does not seem to work from root directory.Is this (as they used to say) a feature? This is on an 11.2 system, upgraded to 11.3 (ran zypper verify to verify. According to it.. all is well).

General :: Grep Or Sed Or Awk For File Manipulation?
Dec 7, 2010Let me *try* and explain what I'm trying to do, and keep in mind aside from a little command line stuff I'm a beginner to any of what I'm asking about.
I have a directory structure something like this:
Code:
/usr/local/chatlogs/
webserver1/
1.chatlog
2.chatlog
[Code]....
So that whatever was captured in the () in the first part of the statement would be used in the 1 in the back part of the statement for every n.chatlog that might be in any of the /webserver directories at that time.

View 1 Replies View RelatedGeneral :: Using 'find' And 'grep' In A For Loop?
Mar 23, 2011I 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 :: Grep The .img, But When Do It Runs Out Of Memory?

General :: Using Wc And Grep With Regular Expressions?
Apr 16, 2010I'm writing a program that works with text files, and I'm trying to create some filters with grep. I have various questions here, so I'll number them for clarity.
1) First of all, I'd like to know what wc -w is actually returning. The word count is less than what gedit is counting in Document Statistics, so obviously gedit is counting something (like newlines) that wc -w is not
2) Secondly, I was wondering if there was a way to grep x number of words. I'm looking for something like the -m option, but returning a certain number of words instead of lines. For example, to find the first 2000 words, do something like grep -someoption 2000 ".*" or using {1,2000}.
3) Finally, I'm trying to filter out headers and footers of a text file but having no luck. The text files are Project Gutenberg files, so they have standardized headers and footers. Here's an example: [URL]...
The header starts with "The Project Gutenberg EBook of" and ends with the line containing "START OF THIS PROJECT GUTENBERG EBOOK" The footers begin with: "End of the Project Gutenberg EBook of" My problem is, grep can find:
