Command 1:
$ touch test"date"
Command 2:
$ date +"%F"
2018-01-16
I want to be able to run the command so the file test_2018-01-16 is created. How do or can I combine the 2 commands above to do this?
$ touch test_"date"
tks
these commands
touch fred-`date +%F`
touch "test-$(date +%F)"
touch "test2_$(date +"%F %T")"
prduce the following files respectively
fred-2018-01-16
test-2018-01-16
test2_2018-01-16 11:51:53

%M. %S") echo "Current Time : $current_time" new_fileName=$file_name. $current_time echo "New FileName: " "$new_fileName" cp $file_name $new_fileName echo "You should see new file generated with timestamp on it.."
I'd use YYYY-MM-DD HHmmss for filenames, unless there is a particular need for timezones or a possible need to parse them into ISO dates; in those cases an ISO date would probably be preferrable.
First, import the module and then get the current time with datetime. now() object. Now convert it into a string and then create a file with the file object like a regular file is created using file handling concepts in python.
You should use double quotes and need to evaluate date +"%F" using command substitution.
$ touch "test_$(date +%F)"
This will create an empty file test_2018-01-15
Double quote helps you create a single file where some options of date command would include a space.
For example, touch test_$(date) will create multiple files, where as touch "test_$(date)" won't.
As pointed out by OP, one would need additional quotes " around the format options, when multiple of them are used:
touch "test_$(date +"%F %T")"
In my world (with Bash) its:
touch fred-`date +%F`
where 'fred-' is the prefix and teh date command provides the suffix
