Functions: cd
unzip all .zip files in /example/directory

Simple but useful little command to unzip all files in a directory.

Know a better way?

If you can do better, submit your command here.

What others think

(1) why are you piping the output of cd to unzip, and (2) why are you escaping the asterisk since you want the shell to expand it...

Sorry about that, I was a little tired when I wrote the command, the pipe was supposed to be a semi colon.

However, I don't want the shell to expand it, I just want to unzip all zip files in a given directory.

Normally you DO want the shell to expand *.zip, because most (unix) programs do not do wildcard expansion on their arguments. Otherwise you're depending on unzip to treat *.zip as a wildcard expression, which unzip happens to do here in this case. But unix commands like ls or even gunzip would interpret the shell argument \*.zip as a single file because they leave wildcard stuff to the shell. Doing either results in an error message

ls \*.zip

ls: cannot access *.zip: No such file or directory

Unzip is the red-headed stepchild here because it has been ported to many different systems, necessitating the wildcard expansion.
