egrep syntax error
I have a script that has been running fine for about a month - now all of a sudden I am getting a syntax error using the egrep command. The command I am using is comparing two files and printing only the unique lines from Second_File to Third_File. Any idea why I am getting the syntax error??


Code:
egrep -v -f Reference_File Second_File | sort -u > Third_File

It must be the "Reference_File".

If it is not too long, display it here.

That made me check the Reference_File - someone had added lines that contained a special character - I removed the lines and now the 'egrep' is working as designed. Thanks!
