It’s pretty annoying supporting both Windows and Linux systems. One of the things that comes up over and over is line endings. You’re about to run a script, and immediate get an error about the bash command not found or something bizarre like that. Fortunately, there are easy ways to fix this.

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.

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.
