Shell Programming and Scripting

Hi Team,

The content of the file is as follows.

Code:

asdf
234
asdf

asdf
dsfg
gh

67
78

The file is in DOS format (not in Unix Format). The file is transferred to Unix. I need a unix command to check the number of blank lines in a input (comming from Windows). If it is greater than 0, then invalid file else valid file.

Please note I have tried the following command. It will work if the file is in Unix format else it will not work.

Code:

grep ^$ filename |wc -l

Can anyone help me out to resolve this issue.

Thanks

Try:-

Code:

grep -v "^[a-zA-Z0-9]" filename |wc -l

OR

Code:

grep "^[[:cntrl:]]" filename | wc -l

Or you can try:

Code:

 awk '/^\r/{c++}END{print c}' file

try also:

Code:

awk 'END {print NR-1}' RS= infile

You can adapt your own command:

Code:

$ grep ^^M$ file|wc -l
