How to find all text file which contains word Exception using find command in Unix ?
find . –name *.txt –print | xargs grep “Exception”

detailed,

it's in a hidden folder called "recycler"

As you know, the Finder hides the standard Unix files and folders from you. You can "Go To Folder..." and type in the name of the folder such as /var/log, but that's fiddly and you still don't see the "dot" files, so for any serious session, it's probably easier to drop into Terminal. Except, there's a terminal command that will make all files and folders display in your Finder. defaults write com.apple.finder AppleShowAllFiles -bool true et voila

The quickest way to set your IP address from the command line is to issue the following command in the Terminal:
sudo ipconfig set en1 DHCP

This will renew your DHCP lease and you will be issued a new IP address from the DHCP server. FYI: en1 is generally wireless/airport, en0 is generally ethernet.

You can check that the IP is set by getting your current IP address from the command line with:
ipconfig getifaddr en1

Doing this before and after will insure you have a new IP.

You can specify an IP address to set via the command line with the following:
sudo ipconfig set en1 INFORM 192.168.0.150

You can also get a new IP address from a DHCP server by bringing down the interface and starting it back up again:
sudo ifconfig en1 down ; sudo ifconfig en1 up

perform action on search results:
rm -f `find ./ | grep "\.\_.*"`

open -a Finder /usr/local/bin (from terminal)

echo $PATH

sudo rm -R
Note there should be a space at the very end of the command line. Then drag and drop your files from Finder onto the Terminal window.
