sed

Name: ________________________________


Use your favorite file (yes, the rime file) for these:
Each is independant of the others.  Show the sed command that
accomplishes the task.

--delete punctuation

--double each space

--double each space and two leading spaces 

--insert a space between each character ("double-blank"). Hint: &

--parenthesize each word

--parenthesize each word and remove spaces

--swap the first two words. Hint: tagging

--swap the first and last words. Hint: 3 tags



Using the country.txt file, build up these seds in pipeline or
multiple editing commands in one sed:
they can probably be done in any order:

--truncate the real numbers (remove decimal point and any digits to its
right)

--replace NULL with \N

--replace comma with tab

--delete apostrophes (hint: use " instead of ' as shell quote)


Using the japan file, build up these seds in a pipeline or multiple
editing commands in one sed:

--apostrophes around the text fields
(?can't use -r and tags together?)

--comma as field separator
