Shell script – find a directory and cd to it

ByTomas Zezula

Quite frequently, I reach for a combo of find and cd. Here is how to do it using a single command.

Let’s create a bunch of nested directories, just for the sake of the exercise:

mkdir -p x/y/z

Result:

tree x
x
└── y
 └── z

Suppose I want to locate the y directory and cd to it:

cd "$(find x -name y)"

Similarly, I might want to locate a text file and open it in my favourite editor:

cd ~
touch x/y/z/test.txt
vi "$(find x -name test.txt)"

SSH Key Fingerprint

ByTomas Zezula

I have recently received an email from GitHub asking me to confirm my SSH key. It took me a while to figure out how to generate the required fingerprint from the saved key file. Here is what needs to be done: ssh-keygen -lf .sshid_rsa.pub 2048 8d:f4:e7:95:76:b4:3d:5f:49:ec:49:79:50:8a:be:91 ..sshid_rsa.pub Credit goes to Chris.
