http://www.unix.com – Hi, I have created a shell script for Server Log Automation Process. I have used find xargs grep command to search the string. for Example, Code: find -name | xargs grep "816995225" > test.txt . Here my problem is, We have lot of records and we want to grep the string 4-5 times. so, it takes around 20 mins to finish the process. so, how to search the string fastly using find xargs command Please Suggest me. Regards, Nanthagopal A (HowTos)

My desired outcome is the following: to recursively search a directory looking for a given string in all found files. The following command is my usual port of call:

find ./ | xargs grep -ns 'foobar'

However, when foobar has quotes the command fails and gives me a > prompt in the shell.

Grep (underscore?) Problem 2 years 6 weeks ago

Hi All

I'm having a problem grep'ing files for a certain string on my server. The command I'm using is:

find .

Hi,

I have used this Code: find .

I have a malware on my server. So I've figured out how to find all that malicious files

grep -r --include*.php "Some String from files" .

That seems work fine!

but how to delete them? I've tried using xargs

grep -r --include=*.php "FilesMan" .

I found an SO called using Find/Grep to search files between specific time of day

Based on that and a Unix SE called Grep command to find files containing text string and move them I ended up with:

find . -type f -mtime -20 | grep -v -e " \(0[012345]\|18\|19\|2[0123]\)" | xargs mv -t daytime/

But it's moving ALL the files.

Pipe find into grep -v 46 weeks 1 day ago

I'm trying to find all files that are of a certain type and do not contain a certain string. I am trying to go about it by piping find to grep -v

example:

find -type f -name '*.java' | xargs grep -v "something something"

This does not seem to work. It seems to be just returning all the files that the find command found.

I have a unix command in a variable, it looks like this:

cmd="find /path/to/webpage -type f | grep -v .svn | xargs grep $@" `$cmd` find: paths must precede expression Usage: find [-H] [-L] [-P] [path...] [expression]

When I try to execute the command $cmd in a bash script, it won't work, however, when I copy and paste the exact same command, it does work.

Hello,

Im using this unix command(in a php file) to remove a certain string and then remove the whitespace left by that string. Unofrtunately in many cases, the files get completely erased.

Is there a workaround?

Hi,

I'm testing nginx-cache-purge and notice that grep searches all file content, and since the cache key is in the second line I would like to limit grep searching.

This is the script I'm using:

github.com/perusio/nginx-cache-purge

The line I would like to change and limit grep search to the Second line is:

Code: find $2 - maxdepth 1 - type d | xargs - P $max_ pa ralle l - n 1
