Bash programming language is similar to any other programming language where you can assign variables, apply conditional statements, loops and arrays. You can perform any task from basic level to complex programs with hundreds of instructions in Bash scripting. To understand Bash scripting, let’s ...
The first line confirms thatxhas received the value of3. On the following lines, the value ofxis printed three times, decreasing by1each time. There are only three iterations wherexequals3,2, and1. The loop breaks whenxreaches0because the conditional statementx > 0is no longer satisfied. ...

Create arrays and access values in them. Iterate over and manipulate values in an array.Conditional Statements (15 min)Conditional statements enable us to essentially decide which blocks of code to execute and which to skip, based on the results of tests that we run. JavaScript supports two co...
We began with the basics, learning how to use ‘foreach’ loops in Bash to iterate over a list of items. We then moved on to more advanced usage, such as iterating over arrays and files. Along the way, we tackled common issues you might encounter when using ‘foreach’ loops in Bas...

👉 The mapfile method is described more extensively in my post on bash arrays. # WRONG [me@linux ~]$ for line in $(cat myFile.txt); do echo "$line"; done a b c white spaced line # CORRECT [me@linux ~]$ while read -r line; do echo "$line"; done < myFile.txt a b c...
For arrays, we already know that the length is given by the length property. What we do is start at the index 0 and iterate as long as the index remains less than the length of the sequence, incrementing it at the end of each iteration. That's because the last element's index is ...
