grep -v $variable filename >newfilename

will remove the line and put the remaining lines in newfilename

One way would be to do this:

grep -v $variable filename > newfile

.. and it came to pass that Stuart Tomlinson

Try echoing a "continuation" character (\c) after the first echo, ie:

echo "This is a line of text at \c" >>file
date +%H:%M >>file

should give you :

This is a line of text at Sunday, 12th october

Alternatively, try embedding the actual time into the line itself, eg:

echo "This is a line of text at `date +%H:%M`" >>file

HTH!!

man echo

Depending on your shell either:

1. -n between the echo and the argument to echo. Eg.
    echo -n "some words\t"
    echo "some more words"
The \t echos a tab character. You could substitute it for a space. The
double quotes are necessary.

2. \c as the last character of the line. Eg.
    echo "some words\t\c"
    echo "some more words"

My shell (Korn on SCO OpenServer) supports both but YMMV.
