Need to remove all the odd lines in this file ( PUBLIC-DIRECTORY-LIST
)? Its for my batch script which can be found below (dropbox batch puburl creator):
for PATH in `cat LIST`
do
echo $PATH
dropbox puburl $PATH
done > PUBLIC-DIRECTORY-LIST
Do I just append the command to prune PUBLIC-DIRECTORY-LIST
at the end of the script?
# awk 'NR%2==0' file
http://www.here.is.a.hyper.link.net/
http://www.here.is.another.hyper.link.net/
我会使用awk,但那只是我:
awk '{if(i++%2)print}' foo.txt
For completeness here is the sed
expression:
sed -e '1d;n;d' file
It is exactly as here except with an extra 1d
command, this deletes the first line and so prints the odd lines instead of the even ones.
