UNIX sed command help
Hi,

I am a new student learning about Unix. Can anyone help with the following sed command. What would this command do?

Code:
sed -n -e '/^s/p'


Any help you can provide would be a big help.

Thanks in advance!

The -n tells it "don't automatically print lines".
The -e tells it 'use the following string as an expression".

I think /.../p expressions mean 'print lines which match this pattern'.

Corona688 is correct. In this specific case, sed will copy whatever lines it finds on its standard input to its standard output if and only if the 1st character on the line is "s".
