find blank lines in a file

[q4s72534]

how do i find blank lines in a file?

 

[SteveR77]

To find the blank lines -

grep '^$' {File name}


If you are looking to strip the blank lines out you will need to use either awk or sed.

To remove empty lines :
sed '/^$/d' filename > newfilename
To remove line(s) with just a space :
sed '/^ /d' filename > newfilename

One regular expression for blank lines (not necessary empty):

/^[  ]*$/
    ^__ Tab char
