Bash quoted array expansion

Question

WHen I write a bash program I typically construct calls like follows:

declare -a mycmd=( command.ext \"arg1 with space\" arg2 thing etc )

\"${mycmd[@]}\" || ech         


        

Answer 1

I like to put the code in a function so it is easier to reuse and document:

function myjoin
{
   local list=("${@}")
   echo $(printf "'%s', " "${list[@]}")
}

declare -a colorlist=()
colorlist+=('blue')
colorlist+=('red')
colorlist+=('orange')

echo "[$(myjoin ${colorlist[@]})]"

Note how I added the comma in the solution because I am generating code with a bash script.

[EDIT: fix problem that EM0 pointed out that it is returning ['blue',]]
