A command I use a lot is:

    cat dos-file.txt | sed -e '1,$s\^M\\g' >linux-file.txt

But that's because I'm always copying files edited on Windows to
my Linux box with the wrong format.  Note that the ^M is ctrl-M
which must be entered on the command line as ctrl-V ctrl-M.

I don't have any examples, but the cut command is one of my
favorites:

    cat test.txt | cut -d= -f1

Will print the first "field" of a file where fields are delimited
by = and "records" are delimited by new lines.
