debian for command iteration code example

Example 1: bash loop

#!/bin/bash

# A simple bash "for loop" example below...
# This loop will run 5 times, and will echo the number in sequence as it goes.
# Mind the double . between the {}
# Note how the variable is called with the $ prefix, which can be done within the "" quotes!

for i in {1..5}
do
   echo "This is loop number $i"
done

# To achieve the same in a single line is also simple

for i in {1..5};do echo "this is loop number $i";done

## Happy coding, my homies! <3

Example 2: bash for i

for VARIABLE in 1 2 3 4 5 .. N
do
	command1
	command2
	commandN
done

Example 3: loop bash

Use for in bash for iterating words in a string or values in an array as:
for value in {1, 2, 3}; do echo $value; done
for value in $(cat arguments_files.txt); do [some_command]; done
And use while for iterating lines from a pipe output as:
cat arguments_file.txt | while read line; do [some_command]; done
