For explanation, see the comments in the code. You may pass arguments without any array like this: bash media automatically builds an array from passed arguments that passed them to function and then you have position arguments. With associative arrays, I don’t believe there’s any other method than iterating. We can loop through the associative array in two ways. The indices do not have to be contiguous.

It seems like yes, the keys and values will always be in the same order, based on the code I found in Bash version 4.3, assoc.c, available here.The keys and values of the array are retrieved by the assoc_keys_to_word_list and assoc_to_word_list respectively. Angular momentum of a purely rotating body about any axis. Example: You mean if array value has space symbols you must quote elements first before pass for accessing value by index in function use $1 $2 $3 ... position parameters. If the local scope isn't necessary, just remove the "local" declaration. Before you think of using eval to mimic associative arrays in an older shell (probably by creating a set of variable names like homedir_alex), try to think of a simpler or completely different approach that you could use instead.If this hack still seems to be the best thing to do, consider the following disadvantages: But what about if we want to pass the array as an argument. i.e. Nothing else. How to pull back an email that has already been sent?

An associative array can be thought of as a set of two linked arrays -- one holding the data, and the other the keys that index the individual elements of the data array. echo ${aa[hello]} # Out: world Listing associative array keys. Following both the suggestions of glenn jackman and ffeldhaus, you can build a function which might become handy: expanding on Luca Borrione’s cp_hash – which didn’t work for me, and I gave up trying to track down the eval expansion issue – I ran into differences before and after bash 4.2. after 4.2(something) this gets a lot easier… but that’s not backwards compatible. In effect, what if the passing of an array is only being done to get a result. You can also update the value of any element of an array; for example, you can change the value of the first element of the files array to “a.txt” using the following assignment: files[0]="a.txt" Adding array elements in bash For more serious scripts, consider as mentioned, putting the keys in its own array, and search it while looking up values. You can also initialize an entire associative array in a single statement: aa=([hello]=world [ab]=cd ["key with space"]="hello world") Access an associative array element.

Use references (best for passing associative arrays): fn() { [ "$1" = "arr" ] || { declare -n arr; arr="$1"; } # The name of reference mustn't match the input coming to the function. Unlike most of the programming languages, Bash array elements don’t have to be of the … There is another solution which I used to pass variables to functions. Making statements based on opinion; back them up with references or personal experience. It's not like bash internally creates a row for 0 with columns labelled 1 and 0.
