Here's a real-life example, slightly edited:
--------------------------
#!/bin/sh
# the first command to sed below contains an embedded '\r', so it may look odd.
sed \
-e 's/
$//' \
-e 's/^"\(#.*\)"/\1/' \
-e 's/ /,/g' \
-e 's/,,*$//' \
-e '/^$/d' \
-e '/^#/s/LLC,200/LLC, 200/' \
$1
--------------------------
This script is used to preprocess the CSV output of Exceed into an ASCII
configuration file used on a Unix-type system (*not* Cygwin). Note that
the literal <CR> cannot be replaced by "\r" here, since sed doesn't
support it on this platform.
