grep -lr string ./ > results.txt

-l will print only the path and file names of the matches.

Search all files of a certain name for a certain string:

grep -lr string ./ | grep filename

Yes, do specify ./ if you are doing all directories within current.

(source and more info)

Find an replace a string in files:
Searching for a way to do this usually leads me to finding fancy scripts that don’t work right, are scary (create temp files, etc) or aren’t recursive. Just have backups at hand and test the following combination of find and sed before unleashing it, because it works great! You can test it by replacing sed with grep

find ./ -type f -exec sed -i ’s/string1/string2/’ {} \;

Within specific file names/extentions…

find ./ -iname \*.htm\* -exec sed -i 's/\-2005/\-2007/g' {} \;

Don’t forget to use escape \ as seen above. And if your strings contain forward slash / just use a different delimiter such as pipe | or escape it.

You can also install rpl, as shown in the source pdf, for even cleaner line of code for executing your find and replace.

(source and more info) A nice pdf to keep by your side.

Since moving from VMware Server to ESXi to host my virtual machines, I’ve been very interested in looking into some more of the advanced features of ESX and ESXi yet most of these require iSCSI.  I remember from a few years back using Openfiler to do some simple samba file sharing, and remembered it supported iSCSI as one method of giving out storage.

Now, I’ve yet to use any of the features of ESX that require iSCSI, or even setup Openfiler to export storage via iSCSI, but I have been using it for simple file sharing and must say I’m quite impressed.

Setup is a breeze, taking about 20 minutes on an older PC. Management is done almost entirely through a web interface, that is very easy to use.  Unlink many of the other appliance packages out there, the web interface is very simple and straight forward.  Very much impressed with that.

Over the next few months I’ll be exploring Openfiler much more, and hopefully getting into some of it’s more advanced features including interface bonding, md devices and clustering.  I plan to keep updating as things more along.

There is also a similar server side fix for this.  Consult man ssh_config and man sshd_config for more details.

dd if=/dev/zero of=10mb-file.bin bs=1024k count=n

Using the above command (and replacing n for a value) allows the creation of empty files with the size specificed. Need a 10Mb file, n = 10. Need a 100Mb file… n = 100. You get the idea.

Luckily Google helped me find a solutation rather quickly, and using information from this site I was able to get things working again.

Basically, I added xkeymap.nokeycodeMap = true to /etc/vmware/config and things started working right. Another on the forum suggested remapping the keys, but I didn’t try that.
