The example runs 'puppet' in a loop for 10 times, but exits the loop before if it returns 0 (that means "no changes on last run" for puppet).

Searched strings:

passthru, shell_exec, system, phpinfo, base64_decode, chmod, mkdir, fopen, fclose, readfile

Since some of the strings may occur in normal text or legitimately you will need to adjust the command or the entire regex to suit your needs.

I found this command on a different site and thought you guy might enjoy it. Just change "YOURSEARCH" to what ever you want to search. Example, "Linux Commands"

This is longer than others on here. The reason for this is I have combined two different matrix commands so it would work on all computers. I logged onto my server through a computer and it worked fine. I logged into my server through a mac and it looked $4!t so I have made one that works through both.

Example of zsh globing, glob qualifier, and substitution:

-Q state that the parameter will contain a glob qualifier.

(**/)(*) is recursive

(.) is our glob qualifier, with states the match is a file "."

The first parameter $1, is then substituted with $2 but with lowercasing '(L)' ... a (U) would of course be from lower to upper.

zmv -Q '(**/)* *(.)' '$f:gs/ /_'
print -rl /**/*(.f:o+w:)

Example of using zsh glob qualifier ...

"." = files

"f:" = files with access rights matching:

o+w = other plus write

Go to "https://twitter.com/search/realtime?q=%23TeamFollowBack&src=hash" and then copy al the text on the page. If you scroll down the page will be bigger. Then put al the text in a text file called twit.txt

If you follow the user there is a high probability the users give you follow back.

To follow all the users you can use an iMacros script.

Uses find, plutil and xpath.

Note: Some applications don't have proper information. system_profiler might be better to use.

It's a bit slow query.

Due to command length limit, I removed -name "*.app" and CFBundleName.

grep -qIm1 . $file
2013-03-28 14:11:51
User: anon1251
Functions: grep
0

This command produces no output, but its exit status is 0 ("true") if $file is text, non-0 ("false") if $file is binary (or is not accessible).

Explanation:

-q suppresses all the output of grep

-I is the trick: if a binary file is found, it is considered a non-match

-m 1: limit "output" to first match (speed up for big files)

.: the match string, "." stands for any character

Usage: e.g. run editor only on text files

grep -qIm 1 . $file && vi $file
sed ?s/[sub_str]/[sub_str]\n/g? [text_file] | wc -l
egrep -v "(^#|^\b*$)"
find /var/www/ -type f -print0 | xargs -0 chmod 644
