While Windows normally has just a single batch language, Linux has many
to choose from. How you accomplish this depends on the shell language
you are using. Since you are new, I'll guess you are using bash, which
is normally the default. Here is a shell script that generates a file
name with a date on the end:
#!/bin/bash
FILEDATE=MyFileName-`date +%Y-%m-%d`
echo $FILEDATE
Enter these lines into file, e.g., filedate.sh. To make this file
executable, at a command prompt, type "chmod +x filedate.sh". Unlike
Windows, file types (e.g., executable vs text) are not determined by
their extensions, so you need to explicitly tell Linux this file can be
executed. Having done that, you can now run it: "./filedate.sh".
