file with blank lines embedded, want to remove them

[confuseddddd]

Have an input file we are reading where blanks lines exist within a record grouping and created a nawk script to read the input and then build separate output files based on user....Want to not have blank lines in file,
how can this be accomplished using nawk??? We currently use a field separator of blank to create the separate user files.

INPUT FILE (just a snippet but have multiple rows and sometimes all detail rows exist and sometimes do not)
HEAD USER


DET1


DET2

DET3

END


WANT OUTPUT TO BE:
HEAD
DET1
DET2
DET3
END



Thanks in advance for the input.

sed '/^$/d' data.file > output

Tried the command sed '/^$/d' data.file > output
and did not remove the blank lines that are embedded between each record in the file....

Anyone have any other suggestions????

Take a look at thread52-522444

All these suggestions are great; however, I am still unable to remove the spaces that start at the end of the record and go to where the ^M previously existed.
The request is to remove all the spaces from the end of the record including the carriage control.

Any suggestions????

Perhaps running od -hc against your file will show what characters you have on the 'blank' lines, then you can construct the sed command accordingly.

Try this:

X=echo "[ \t\r]\c"
sed -e &quot;s!${X}*&quot;'$!!' <InputFile >OutputFile

Hope This Help
