UNIX for Advanced & Expert Users

Hi,

I was very surprised to not be able to find an answer to this question despite my best efforts in Google and elsewhere. Maybe it's a good thing as it forced me to finally become a member in this great forum that i use frequently.

Ok my question:

I want to be able to sort files inside a directory (that *may* of course contain sub-directories) according to the *latest modification date*.

e.g. after execution the command/script, I should have a list:

./myrootdir/dir2/subdir1/testing/file_hello.php 22M Jan 15 17:32
./myrootdir/testingteo.txt 12K Jan 03 12:22
./myrootdir/utilities/myscript.ksh 750M Jan 01 11:15
...
... etc.

Maybe I didn't check properly but I couldn't find it! A simple ls -lrt will give me only local files inside the current directory.
I think this would be a very useful tool to check which files were lately modified and/or added inside nested directories.

Need:
My (web shared) server was recently hacked and I wanted a "fast" way to check what files were modified/added.
Would it be difficult to add the same result but for specific file types? e.g. php, cgi, ksh only.

Thanks in advance!

Which OS are you on? I'm assuming Linux here, as you said it's a shared hoster:

Code:

find . -type f -name '*.php' -exec ls -ltr {} \+

Otherwise:

Code:

find . -type f -name '*.php' -print | xargs ls -ltr

Beware, though, that in the case of a lot of files found the list might not be 100% correct, as ls can only sort the files found on the command line, which might be fewer than there are really.

A little hint for the next time: keep a current list of cryptographic checksums (at least MD5 and SHA1, maybe more) offsite, so you can quickly compare any changed/removed/added files.

thanks,

Ok, then if a simple find+xargs can't guarantee that will do the trick depending on the number of files what will?

Also, if you have a link to look into the cryptographic stuff, I would appreciate it.

thanks again!

Again, assuming that you run some kind of current Linux (as you haven't told us the OS yet):

Code:

find . -type f -name '*.php' -print | while read file; do stat -c '%y %n' $file; done | sort -n

should give you what you need. However, this depends largely upon the stat utility shipped with Linux (meaning GNU stat), it most probably won't work with that of another OS.

As for the checksums: most Linux distributions and *BSDs (dunno about Solaris) ship with at least md5sum, usually sha1sum and sha256sum too. Those can be used to create and verify cryptographic checksums for a/a lot of file(s).
