Thanks for the report. But I am not able to recreate your failing test case. It worked fine for me on both HP-UX and Linux running recent versions of the GNU utilities.
You did not include the operating system that you were running on nor the versions of the utilities involved. That would be required in order to make further progress at debugging this. However I see in a small snippet: > For the time being I have replaced cat.exe with a shell script as follows: The fact that you are running cat.exe with a .exe ending leads me to believe you are running a port of the GNU operating system utilities on a MS-Windows system. Perhaps you are using the Cygwin toolkit and perhaps not. I can't tell. If you are using Cygwin then you should see if an update is available. If not then you should make your report directly to them.

Interestingly enough if you dont include a carrage >return after the 'there' in the file then it seems to pick up 'cat file.txt | egrep >-e "e$"' just fine or if you try this: 'cat file.txt | egrep -e "$"' it also seems to >do what you would expect. > > For the time being I have replaced cat.exe with a shell script as follows: > --------------------------- > #!/bin/sh > > egrep -e "^" $1 > -------------------------- > > and that seems to be working for me.
