Tagged: sed, shell
Below command helps me to remove only blank or empty lines from a file. Bit it not removes a line with white space.
sed '/^$/d' filename > filename.temp
sed '/^ *$/d' filename > filename.tmp
filename.tmp > filename
This will remove blank lines and lines with only white spaces from a file.
