PLease use code tags as required by forum rules!

There you are - it's neither *nix nor MAC, it's DOS: 0d 0a as line terminator. Reformat with dos2unix (I don't know about dos2mac) and try again.
Or, try /^\s*\r$/d for your sed command.

Thanks!

What is the best way to save excel files to make them work in the terminal?

csv (comma separated values/variables) or <TAB> delimited files is fine; just make sure the line terminator is selected appropriately.

The line terminator shouldn't matter here -- DICER\r matches the regex DICER.

The carriage returns may be messing up your console, though. Try grep -l. It will print the filename instead of the file, if it happens to match.

Code:
grep -l DICER filename

Sorry for bothering again.
I have my file:

Endonuclease_GO-0004519_Filter.csv
Code:
E3C5X5

DCL4
DICER
CAS1A
CAS2A
APE

T2BA
ENDOA

I saved it as windows comma separated csv:

Endonuclease_GO-0004519_Filter.csv |head
Code:
0000000   E   3   C   5   X   5  \r  \n  \r  \n   D   C   L   4  \r  \n
         45  33  43  35  58  35  0d  0a  0d  0a  44  43  4c  34  0d  0a
0000020   D   I   C   E   R  \r  \n   C   A   S   1   A  \r  \n   C   A
         44  49  43  45  52  0d  0a  43  41  53  31  41  0d  0a  43  41
0000040   S   2   A  \r  \n   A   P   E  \r  \n  \r  \n   T   2   B   A
         53  32  41  0d  0a  41  50  45  0d  0a  0d  0a  54  32  42  41
0000060  \r  \n   E   N   D   O   A  \r  \n   N   F   I  \r  \n   R   E
         0d  0a  45  4e  44  4f  41  0d  0a  4e  46  49  0d  0a  52  45
0000100   C   U  \r  \n   Y   O   K   F  \r  \n   Q   9   M   C   N   1
         43  55  0d  0a  59  4f  4b  46  0d  0a  51  39  4d  43  4e  31

When I try to remove blank lines, it does not do it:

Code:
sed /^\s*\r$/d   Endonuclease_GO-0004519_Filter.csv |head

E3C5X5

DCL4
DICER
CAS1A
CAS2A
APE

You must quote sed command either \s \r * are interpreted by shell:
Code:
sed '/^\s*\r$/d'   Endonuclease_GO-0004519_Filter.csv |head

Regards.

It still does not work:
Code:
sed '/^\s*\r$/d' Endonuclease_GO-0004519_Filter.csv |head
E3C5X5
