What a great day today in terms of Unix shell discoveries.
Early in the morning, I bought iSSH for iPad and was blown away by how functional it was. The iPad is actually useful now besides being an overpriced e-reader.
In the afternoon, someone pointed out ack to me instead of using grep. Faster search, here I come.
Finally, just a few minutes ago, I discovered “cd -“, “pushd” and “popd”. No more need to set temporary aliases when I bounce back and forth between directories.
