bash loop coutner 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 loop counter
TEMPFILE=/tmp/$$.tmp
echo 0 > $TEMPFILE
# Loop goes here
# Fetch the value and increase it
COUNTER=$[$(cat $TEMPFILE) + 1]
# Store the new value
echo $COUNTER > $TEMPFILE
# Loop done, script done, delete the file
unlink $TEMPFILE
