I have an Angular script that needs to be modified to invoke a bash (shell) script and pass a filename to that script invoked. Both scripts are written and work but the bash script has been run manually from a command line in the past, and now I need it to run automatically. The bash script will create a copy of a file that has been uploaded to our site. The bash script will need the filename passed to it to name the copy correctly. This is in a node.js environment. I need to have this working in 2 days.
