This blog post is 12 years old! Most likely, its content is outdated. Especially if it's technical.
I often need to know the path to a file so that I can put that in an email for example. The only way I know is to copy and paste the output of pwd followed by a slash / followed by the name of the file. This is too much work so I wrote a quick bash script to combine this into one. Now I can do this:
$ cd bin
$ pwdf todo.sh
/home/peterbe/bin/todo.sh
I call it pwdf since it's pwd + file. Here's the code for the curious:
#!/bin/bash
echo -n `pwd`
echo -n '/'
echo $1
Is there no easier way built in into Linux already?

If you are using bash, you can use
echo $PWD/todo.sh
Not sure if it was part of GNU coreutils when you wrote this, but there's readlink[1]. Use:
readlink -f the-file
