Something like:

Code:

awk '$1 ~ /^[0-9]/{print}'

Regards

Code:

grep "^[0-9].*" <filenames>

Hi, whether the above one or this one:

Code:

grep "^[0-9][0-9]*" <filenames>

is the correct regular expression to filter the lines that contain only numeric values (numbers)?? or both are same (can be used interchangeably)?

Code:

grep "^[0-9][0-9]*" <filenames>
