Hi all
sed '/^$/d' file1.txt
removes the blank lines and file1.txt has to be
affected by this command.
I mean the file1.txt should contain non-empty lines.
Good question. I thought it was not possible but got
to know that this can give u what u want.
$ perl -pi -e 's/^\s$//' file1.txt
Unforunately I am forced to say that perl is
counterintuitive when it comes to certain things...
Even in regexes where it should have been backward
compatible with flex and sed regexes, sometimes things
just don't work as you expect.
I mean why say /^\s$/ when it is enuf to say /^$/?
Anyway hope you got what you wanted...

Girish
