Looping through files in a directory
Looping through files in a directory is a common task and can be performed in most programming languages. Shell scripting is particularly useful when creating scripts that update all files within a project or even a simple backup script.
// loop through files in a directory
files=$(ls /var/www/backups/)
for file in $files
do
// do some stuff
done
Sometimes I like to perform my functions on files that are sorted:
// loop through files in a directory and make them sorted
files=$(ls /var/www/backups/ | sort)
for file in $files
do
// do some stuff
done
Once you know how to perform the above code you'll find it easy to create scripts for your crontab.
