fish also supports :ref:`and <cmd-and>`, :ref:`or <cmd-or>`, and :ref:`not <cmd-not>`. The first two are job modifiers and have lower precedence. Example usage::
> cp file1.txt file1_bak.txt && cp file2.txt file2_bak.txt ; and echo "Backup successful"; or echo "Backup failed"
> cp file1 file1_bak && cp file2 file2_bak; and echo "Backup successful"; or echo "Backup failed"
Backup failed
As mentioned in :ref:`the section on the semicolon <tut-semicolon>`, this can also be written in multiple lines, like so::
cp file1.txt file1_bak.txt && cp file2.txt file2_bak.txt
cp file1 file1_bak && cp file2 file2_bak
and echo "Backup successful"
or echo "Backup failed"
