Why you can use a bash for loop in one line If you use bash on the command line, this will not guarantee that for loops are inserted into the script. In order to prevent this, it is easiest to use loops directly

Line 1starts theforloop at zero, increments by one, and ends at two, inclusive. Line 3starts the nestedforloop at zero. The value increments by one and ends at nine inclusively. Line 5prints the values from theforloops. The nested for loops through all numbers three times, once for eac...
for i in {0..20..5} do echo "Number: $i" done Over Array Elements While one can use the for loop for numbers and strings, programmers can even leverage the same to repeat over a range. For example, we will state an array - Players and iterate over each of the elements of the ...

You can accomplish that by iterating a second list based on your first list through nested loops. This gets a little hard to follow when you're doing it as a one-liner, but it can definitely be done. Your nestedforloop gets executed on every iteration of the parentforloop. Be sure to...

“bash”. As we have to use the one-line “while” loop in the code, we are fulfilling our promise here. The while loop started with the keyword “true” states that the loop will continue to execute until “true”, i.e., it will not stop its execution until the user ends the ...
There are two types of bash for loops available. One using the “in” keyword with list of values, another using the C programming like syntax. This article is part of our on-going bash tutorial series. This explains both of the bash for loop methods, an
