scripts uses bash idioms in ash script

[solsticedhiver]

the scripts in scripts directory use a lot of bash idioms that will only run in bash and not ash or dash.

Please use bash in shellbang instead.

Some example:

• if [[ ]] is bash only use if [ ] instead
• accessToken=${accessToken//"\""/} string replacement is not available

Possible bug:

line 22 of hideme-accesToken.ash: if [[ $? == "22" ]];

You compare the output result which is an integer to a string. that will always be false. Use something like if [ $? -eq 22 ] of better if [ $? -ne 0 ]
