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
Bash For Loop In One Line with Files # for i in *; do echo "Found the following file: $i"; done # for i in `cat filelist.txt`; do echo ${i}; done; if a line may include spaces better use a while loop: # cat filelist.txt | while read LINE; do echo "${LINE}"; done ...

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 each outer loop value. The output prints each number combination to the console and ent...
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...
. Let's compare this with a cleaner, better structured, modern lookingforloop: for ((i=1;i<=5;i++)); do echo $i; done This simpleforbased Bash one-liner (a term often used in Linux/Bash circles to conceptualize a mini-script written on a single line) will print the numbers 1 ...
The program for the one-line while loop is complete and ready to get executed. Save it with the “ctrl+S” and exit the file with the “Ctrl+X” shortcut. After the file exit, we have executed it with the “Bash” instruction. The program code started to display the string “Hello...
