In this tutorial, we are going to learn different ways to loop or iterate through an array of objects in JavaScript. First way: ForEach method Let's use es6 provided forEach() method which helps us to iterate over the array of objects:

The syntax is as follows: for var in "$ {ArrayName [@]}" do echo "$ {var}" # do something on $var done. Create a shell script as follows: #!/bin/bash # define file array files = (/ etc /* .conf) # find total number of files in an array echo "Total files in array : $ {#files [*]}" total = $ {#files [*]} # Print I'm trying to iterate over a variable that might be either null or an array of strings.

With this syntax, you will loop over the users array, with each name being temporarily stored in u. The [@] syntax tells the interpreter that this is an indexed array that we'll be iterating over. There are quite a few ways we can use array loops in programming, so be sure not to limit yourself to what you see here. arr=("sharlock" "bomkesh" "feluda" ) ##declare array len=${#arr[*]} # it returns the array length #iterate with while loop i=0 while [ $i -lt $len ] do echo ${arr[$i]} i=$((i+1)) done #iterate with for loop for i in $arr do echo $i done #iterate with splice echo ${arr[@]:0:3} Iterate array using loop over ssh A simple script: #!/bin/bash test=test test1=(test1 test2 test3) echo ${test1 } ssh server 'echo '$test'; echo '${test1 }' ; echo '${test1}' ; for m in $(seq 1 $(echo '${test1 }' | tr " " " " | wc -l)); do echo $m ; echo '${test1}'; done'Here is the result: test1 test2 test3 testing Script to iterate over several options Have two 3 files which has list of servers,users and location and base url which is common on every server A = server1 server2 server3 B = user1 user2 user3 C = dom1 dom2 dom3 baseurl=/opt/SP/ and what i have to achieve is below via ssh from REMOTE SERVER for it's first iteration it 3. The keys are accessed using an exclamation point: ${!array[@]}, the values are accessed using ${array[@]}.

I need to iterate on an array and expand the array while iterating. How do I do it in BASH? For example: req="a b c d" read -a MODULES << 

jq -c '. []' input.json | while read i; do # do stuff with $i done iterarr "$ {myarr [@]}" will expand to iterarr '/dir1/file1.md' '/dir1/file2.md' 'README.md' and in your loop you only reference the first argument with "$1".
