I try to iterate over an associative array in Bash.
It seems to be simple, but the loop doesn't follow the initial order of the array.
Here is a simple script to try:
#!/bin/bash
echo -e "Works...
Why don't Bash associative arrays maintain index order?
I'm creating associative arrays to process in a for loop but i'm getting some strange results in index order. Please take a look at this example script:
#!/bin/bash
declare -A test1=(
[d]=1w45...
I am following this thread: https://stackoverflow.com/a/19742842/5057251
for typeset (or declare) in ZSH, not BASH.
#Declare (or typeset) an array of integers
#declare -ai int_array
typeset -ai
Why are "declare -f" and "declare -a" needed in bash scripts?
Sorry for the innocent question - I'm just trying to understand...
For example - I have:
$ cat test.sh
#!/bin/bash
declare -f testfunct
testfunct () {
echo "I'm function"
}
testfunct
d...
difference between "function foo() {}" and "foo() {}"
I can define bash functions using or omitting the function keyword. Is there any difference?
#!/bin/bash
function foo() {
echo "foo"
}
bar() {
echo "bar"
}
foo
bar
Both calls to functions...
In PHP, strings are concatenated together as follows:
$foo = "Hello";
$foo .= " World";
Here, $foo becomes "Hello World".
How is this accomplished in Bash?
