Thankyou
Yes sorry, the command you mentioned
sed ..... <$filename >$newfilename # incomplete command, not sure what you need the sed to doI am using a SED command to delete a blank lines in an existing file and it opens a newfile with the new data. I then run it through another SED command which extracts the searched variable(s) that the user inputs. So using

sed '/NZDT/{N;s/\n//;}' access.log > testfile2003121130
then using another SED command with a variable (or two variables) which have been entered by the user (variableyyyy) - putting that in the next SED command and running that on the newfile testfile2003121130. .
so
user inputs first entered data when prompted "john"
user is prompted again if they want to enter another criteria to search at the same time "smith" (search for john smith) - thats not the actual text I am searching for just an example.

sed '/NZDT/{N;s/\n//;}' access.log > testfile2003121130
cat testfile2003121130 | sed -e '/./{H;$!d;}' -e 'x;/variableyyy/!d'
print the result to screen.
I am hoping to automate this rather than put in two separate commands.

Hope that may clarify what I am trying to do.
Thanks again regards
