Hi all

I have big file as below and would like to know how many line eg: wc -l file but can't figure out how to know

If I type wc -l file, I only get the 1023 but it includes the space When I use cat file | tr -d "\r \n". it gives me "adrian alice......" I need it as fileB and then wc -l fileB.

If those lines between the names are empty lines you might try : cat bigfile | egrep -v '^$' | wc -l

or if you want the names into a second file : cat bigfile | egrep -v '^$' > fileB

Regards,

Michel

Or if you don't mind loosing replicates: cat bigfile |sort |uniq > fileB
