-a non-blank line-
Here are three examples of using tr on a 4.2bsd system.
Does anyone have comments?
% tr -cs A-Za-z '\012' <file1 >file2
creates a list of all the words in `file1' one per line in `file2',
where a word is taken to be a maximal string of alphabetics.
the second string is quoted to protect `\' from the shell.
012 is the ascii code (in octal) for newline.
% tr A-Z a-z
will translate all upper case characters into lower case.
% tr -d '\015' < in > out
will read from file 'in', deleting all ^M (carriage return) characters
and storing the result into file 'out'. 015 is the ascii code (in octal)
for carriage return.
