Convert file path to URI in bash

Question

How can I convert a file path to an URI in the command-line?

Example:

/home/MHC/directory with spaces and ümläuts

to

file:///home/MHC/directory%20with%20spaces%20and%20%C3%BCml%C3%A4uts

Answer 1

One way to do this is using urlencode (install it on Ubuntu via sudo apt-get install gridsite-clients).

urlencode -m "$filepath"

will convert the path to an URI. The "file://" part of the URI will be left out, but you can easily add that via a bash one-liner:

uri=$(urlencode -m "$1"); echo "file://$uri"

or directly

echo "file://$(urlencode -m "$1")"

or

echo -n file://; urlencode -m "$1"

You can also use the Perl module URI::file directly from the command line:

$ path="/home/MHC/directory with spaces and ümläuts"
$ echo $path | perl -MURI::file -e 'print URI::file->new(<STDIN>)."\n"'
file:///home/MHC/directory%20with%20spaces%20and%20%C3%BCml%C3%A4uts
$
