Bash script to use wget to download a file and restart a service-CodePudding

I have 2 commands I want to run one after another and would like to create a script and add it to cron. My commands are:

wget http://browscap.org/stream?q=Full_PHP_BrowsCapINI -O /etc/php/7.2/mods-available/browscap.ini
service php7.2-fpm restart

Is it possible to have it download the file, wait till it completes then run the restart script?

Thanks for the help.

CodePudding user response：

To run the second command after your wget download completes, separate the two commands with the double ampersand &&

As a one-liner:

wget http://browscap.org/stream?q=Full_PHP_BrowsCapINI -O /etc/php/7.2/mods-available/browscap.ini && service php7.2-fpm restart

The command after the double ampersand && should only run if the first command (the wget download) successfully completes.

CodePudding user response：

Per the wget manual use the wait option when passing your download command (type man wget from CLI to see more information):

wget -w seconds http://browscap.org/stream?q=Full_PHP_BrowsCapINI -O /etc/php/7.2/mods-available/browscap.ini 
service php7.2-fpm restart

or 

wget --wait=seconds http://browscap.org/stream?q=Full_PHP_BrowsCapINI -O /etc/php/7.2/mods-available/browscap.ini
service php7.2-fpm restart

This will force the script to wait the specified number of seconds before proceeding with the service restart command.
