this works fine with the test file I posted, but it does not seem to work with my actual data as shown below:

Code:
$cat s5
#miRNA    s5_read_count    precursor
hsa-let-7a    3993760    hsa-let-7a-1
hsa-let-7a*    52    hsa-let-7a-1
hsa-let-7a    3994154    hsa-let-7a-2
hsa-let-7a-2*    15    hsa-let-7a-2
hsa-let-7a    3991037    hsa-let-7a-3
hsa-let-7a*    52    hsa-let-7a-3
hsa-let-7b    308568    hsa-let-7b
hsa-let-7b*    37    hsa-let-7b
hsa-let-7c    2419205    hsa-let-7c

Code:
$ sed "/\*$/d" s5
#miRNA    s5_read_count    precursor
hsa-let-7a    3993760    hsa-let-7a-1

hsa-let-7a*    52    hsa-let-7a-3
hsa-let-7b    308568    hsa-let-7b
hsa-let-7b*    37    hsa-let-7b
hsa-let-7c    2419205    hsa-let-7c

How will it work, if you change your input.

Try this
Code:
sed "/^[^ ]*\*/d" file

Code:
awk '!($1~/*$/)'  infile

If no matter where is the *, the line will be removed, you can use grep -v directly.

Code:
grep -v \* infile

Code:
grep -v "\*$" fileWithStar.txt > fileWithoutStar.txt
