url-tail.sh
This bash script monitors url for changes and print its tail into standard output. It acts as "tail -f" linux command. It can be helpful for tailing logs that are accessible by http.
Installation
Script needs curl to be installed. Many Linux distributions as well as Mac OS X already have curl installed. On Ubuntu you can use this command to install curl:
sudo apt-get install curl
Then copy script to your computer:
sudo curl -o /usr/bin/url-tail.sh -s https://raw.github.com/maksim07/url-tail/master/script/src/url-tail.sh
sudo chmod +x /usr/bin/url-tail.sh
Usage
To start tailing url just run
url-tail.sh http://example.com/file_to_tail
Script will stop automatically if remote file will be re-created e.g. in case of log rotation.
If you want to start url-tail with some data displayed you can tell it how many bytes to fetch from the end of file
url-tail.sh http://example.com/file_to_tail 1000
