You can use following tricks to exclude files 

Using Bash extglob ( not it will exclude file1.txt, I've used ls command for demo )

rahul@lappy:/tmp/test$ ls -rlht
total 0
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file1.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file5.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file4.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file3.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file2.txt
rahul@lappy:/tmp/test$ shopt extglob
extglob         on
rahul@lappy:/tmp/test$ ls -rlht !(file1.txt)
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file5.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file4.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file3.txt
-rw-rw-r-- 1 rahul rahul 0 Dec 22 15:36 file2.txt

Using find command 

find . -type f ! -iname 'file1.txt' -exec ls -lrt {} \;
