Hi the answer is:

sed ‘/^$/d’ example_file1 > example_file2

this should do it:

sed ‘/^$/d’ file1 > file2

grep -Ev ‘^$’ example_file1 > example_file2

Apart from an awk script to do the same, i prefer writing one line of bash to do the trick. input: example_file_1 output: example_file_2



cat example_file_1|while read line;do if [ "$line" != "" ]; then echo "$line"; fi; done>example_file_w
