xopen : shell function to have verbose xdg-open : Mac's "open" alternative for Linux

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
}

console and json

recently Alan posted a very nice aticle around prettifying json, reminded me of <this draft>... he posted 2 out of 3 utilities I was gonna mention... so here is 3rd and the shell profile way to use first 2

$ sudo wget -c -O /etc/profile.d/a.json.sh https://raw.github.com/abhishekkr/tux-svc-mux/master/shell_profile/a.json.sh

it contains 2 functions available at shell

# usage example:
# $ json_me 'echo {"a": 1, "b": 2}'
# $ json_me 'curl http://127.0.0.1/my.json'
json_me(){
bash -c $@ | python -mjson.tool
}

# requirement: $ pip install pjson
# usage example:
# $ pjson_me 'echo {"a": 1, "b": 2}'
# $ pjson_me 'curl http://127.0.0.1/my.json'
pjson_me(){
bash -c $@ | pjson
}

3rd utility is 'jq', an awesome utility which prettifies an perform sed-like operations on json. This tutorial describes all its magical powers.
