I have been googling, but cannot find that works for me.

I have a text file tmp.out with contents:
sadfsdf sdfosuidhfousdhof soduhf osdfu osudfhosudhfd
sdfgsdfg
asdfiojhsdf asdoludhflsdjfhskldjfhsdjdlfsjdhnlj h sdja
ouahsdjdafkljsa
oljhljh

I have another file tmp_memrecno.dat that has numbers:
5
3

I want to delete lines (read from tmp_memrecno.dat) from file tmp.out.

Here is what I have so far, but doesn't really work:
while read line
do
sed "$line"'d' test.out > tmp.out
done < tmp_memrecno.dat

Basically, the end result of file test.out should be
sadfsdf sdfosuidhfousdhof soduhf osdfu osudfhosudhfd
sdfgsdfg
ouahsdjdafkljsa

one way -

awk ' FILENAME=="tmp_memrecno.dat" { arr[$0]=1}
        FILENAME=="tmp.out" {
              if( FNR in arr){ continue}
              print $0
        } ' tmp_memrecno.dat  tmp.out > tmp.newfile

This prints an error:

Syntax Error The source line is 5.
The error context is
} >>> tmp_memrecno. <<< dat tmp.out > tmp.newfile
awk: 0602-500 Quitting The source line is 5.

See the edit above

Thanks dude... you are the best.

How would you use unix variables (tmp1=tmp_memrecno.dat and tmp2=tmp.out) in awk; for example $tmp1 and $tmp2.

awk -v tmp1="$tmp1" -v tmp2="$tmp2" ' {  print tmp1, tmp2} '  somefile
