25.17 An Alias in Case You Don't Have tail

Some System V UNIX versions don't support the tail command (25.14 ) . Here are a shell function and alias named ptail that give you an equivalent:


ptail() { sed -e :a -e '$q;N;11,$D;ba' $1; }

alias ptail sed -e :a -e \''$q;N;11,$D;ba'\'

This prints the last ten lines of a file. (Greg Ubben wrote ptail .)
