: how to use tr to
: replace the following text:
:
: "thank%
: you"
:
: with "thank you".

> tr -s '%\n' ' '

Um, no. That will remove all but the first % and newline in the file, and collapse all multiple spaces to one space.

The *correct* answer is that it cannot be done with tr; the correct tool is sed:

sed '/^thank%$/{
N
s/^thank%\nyou$/thank you/
}'

NB, -d removes a set, not a sequence:

echo aabbccabcd | tr -d 'abc'

The result is not 'aabbccd', but merely 'd'
