Shell scripting: Absolute path name of a file given as parameter

[Aitor San Juan]

Hi List,

Just a simple question.

I have developed a shell script that, among other things, shows the filename
that was specified as a parameter.

However, when I invoke the script and the file is located in the current working
directory, it just shows: ./my_input_filename

I'd like the script to show the full path name of the input file. I wonder
whether there is or not an equivalent to %~f1 (Windows Batch file programming).
This parameter extension expands parameter %1 ($1 in shell scripting jargon) to a
Fully qualified path name.

Any hint would be highly appreciated.

Thanks in advance.

Aitor.
