I'm trying to figure out how to display the contents of a file through unix where the spaces and tabs are marked somehow. I know how to display the files with tabs (aka
cat -T filename) but I've been trying to figure out how to show the spaces as well.
cat -A filename doesn't work for me, and only replaces tabs with
^I and places
$ at the end of the line. How can I utilize
cat to print out a file with all tabs and spaces clearly marked?
There's a standard unix tool for character substitution. In this example, I'm replacing spaces for * and tabs for &:
$ cat tmp space tab space tab end tab space tab space end $ cat tmp | tr " " "*" | tr "\t" "&" space*tab&space&tab&end tab&space&tab*space*end
