I have been using xdg-open for sometime now, it’s a utility similar to “open” utility popular among MacOSx users.

It enables you to open any file in the default “open with” program assigned to it’s type. So, just passing any type of file to this utility would let you open it in the program it’s supposed to open.

What is xdg-open?

There is just this little shell function, that makes your xdg-open usage a bit more verbose in case of errors (bad-syntax/ghost-file/ghost-program/open-failure) faced about the reason for it. And also shortens the access util name obviously.

xopen ()
{
xdg-open “$@”;
_TMP_EXITCODE=$?;
if [ “${_TMP_EXITCODE}” == “1” ]; then
echo “[ERROR:] Error in command line syntax”;
else
if [ “${_TMP_EXITCODE}” == “2” ]; then
echo “[ERROR:] One of the files passed on the command line did not exist”;
else
if [ “${_TMP_EXITCODE}” == “3” ]; then
echo “[ERROR:] A required tool could not be found”;
else
if [ “${_TMP_EXITCODE}” == “4” ]; then
echo “[ERROR:] The action failed”;
fi;
fi;
fi;
fi;
return $_TMP_EXITCODE
}
