hi,

I am trying to remove all the line containing this hit 'no hits found' from a big tabular file.

I have tried this command:

$ sed '/no\hits\found/d' filename

but is not waorking... can someone help me???

F.

sed '/no hits found/d' filename
why did you replace spaces?

I have tried with no space, but is still not working

$sed '/no hits found/d' blastparse_protein.txt > blastparse_removed_no_hits

for me that works perfectly, probably you mistyped or missed something. Can you please show us what was not working

those are some lines from my file :

NODE_26_length_67_cov_1.000000_2 17 No hits found
NODE_26_length_67_cov_1.000000_3 30 No hits found

I need to remove all the lines with the No hits found argument

done sorry.. I was spelling no instead of No .. Thank you

Can I ask you.. how can I set the command in order to keep only the line with the NO hits found argument???

if you want to say thanks just press YES.

I'm not really sure what do you need, try this:

sed '/no hits found/p;d' filename
or
grep 'no hits found' filename

Oh right ... grep should work ...

Thank you so much for the advice ^_^
