Error comparing files with bash script

Question

I have two txt files of this nature:

ENSG00000002587 
ENSG00000002746 
ENSG00000008300 
ENSG00000015413

When I try to compare them using the script

$ comm -23 <(sort file1.txt|uniq)> <(sort file2.txt|uniq)>

I get the following:

bash: syntax error near unexpected token 'newline'

I have recently changed computers; this worked fine on my previous computer. Any advice would be appreciated.

Your command doesn't look right to me. Remove the >. The syntax for process substitution is <(command_list), not <(command_list)>.

Try:

comm -23 <(sort file1.txt|uniq) <(sort file2.txt|uniq)
