06 - For cycle in the bash


The construct allows to repeat for a given number of times a code block code1. The number of the current cycle is saved in current_cycle. After in you can write which numbers the variable current_cycle must assume. The structure is:

for current_cycle in 1 2 3 4 5; do

For example, to cycle 5 times, you can write:

# This script executes 5 cycles in which the variable
# current_variable takes the values 1, 2, 3, 5, 10

for current_variable in 1 2 3 5 10; do
  echo "Current cycle: $current_variable"

A special element is the asterisk (*). It allows to execute for as many times as the number of files contained in the current folder.
