Mounting multiple partitions on a disk

Is it possible to improve the code of this bash script? ... or should I just use another language? (If so, which one would fit the best the situation, according to you?)

Here is the code (simplified, to emphasis the problem):

#!/bin/bash
# mountDDE mount the partitions of the disk b.
# If arguments are passed, it will mount the specific partitions, a, b or c.

if [ -v "$1" ] # If no argument is passed, act on all partitions.
then a=t
    b=t
    c=t
fi

while [ -n "$1" ] ; do
    if [ $1="a" ] # We test the argument(s), to know which partition has to be mounted.
    then a=t
    elif [ $1="b"] # I hate redundunces
    then b=t
    elif [ $1="c"] # Again...
    then c=t
    fi
    shift
done

[ $a="t" ] && sudo mount /dev/sba /media/ba # I'll actually use uuids.
[ $b="t" ] && sudo mount /dev/sbb /media/bb # Not direct paths, like here.
[ $c="t" ] && sudo mount /dev/sbc /media/bc

To me, this code is redundant. Is there any more efficient/better way to do it ?
Which language should I use for this task?

Since you're using bash (I assume a recent version of bash), you can use some advanced features, like associative arrays and indirect variables

#!/bin/bash

# If no argument is passed, act on all partitions.
if (( $# == 0 )); then
    a=t b=t c=t
else
    for arg; do
        if [[ $arg == a|b|c ]]; then
            declare $arg=t
        else
            echo "ignoring argument '$arg'"
        fi
    done
fi

declare -A uuids=( [a]=1234 [b]=3456 [c]=5678 )

for dest in a b c; do
    if [[ ${!dest} == t ]]; then
        sudo mount /dev/sb$dest "${uuids[$dest]}"
    fi
done

Note that the [ command acts differently when given different numbers of arguments. With just a single argument (such as [ $a="t" ]), you'll get a success exit status if the argument is not empty (and the string "$a=t" is not empty no matter the value of $a). You have to put spaces between all the operators and operands for [ and test and [[.
