The
for..in..do..done 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
code1
done
For example, to cycle 5 times, you can write:
#!/bin/bash
# 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"
done
A special element is the asterisk (*). It allows to execute
for as many times as the number of files contained in the current folder.
