Renaming a file: adding a date

[technossomy]

From a daily file the constituent data needs to be extracted and the resulting file should be renamed. These are the components:

Data extraction:
cut -d, -f 1,28,29 foo.csv > foo.txt

Renaming: the following file is executed:
#!/bin/sh
dt=`date +%Y%m%d`
cp foo.txt foo$dt.txt

How can the steps be combined into one line?

Thank you for your information in advance

Use $() to wrap around your executable code:

cut -d, -f 1,28,29 foo.csv > foo$(date +%Y%m%d).txt
