One extra point-- Scrutinizer did a great job of showing possibilities.

Some UNIXES like Linux sed allow for "edit in place"

So for sed - the -i option does that:

Code:

# no option
sed 1d file >newfile
mv newfile file  # back to the starting name

# -i option
sed -i 1d file
# you now have file with the first line removed, no redirection or renzming
