This looks like something sed should be able to do, but I
haven't had any luck at all. I wanted to remove any whitespace
that has accidentally gotten added to the beginning or end of
some lines of text. I made a test file that looks like:
left justified.

This fails to remove multiple occurences of the [[:space:]] class.
There are at least the following ways:
sed -i -e 's/^[[:space:]]*' -e 's/[[:space:]]*$//' file ...
perl -pi -e 's/^\s*(\S.*\S)[ \t]*$/$1/' file ...
The first one seems more

why not use just (you can change the - separator to / as above):
sed -e 's-^ *--g' -e 's- *$--g'
usage examples:
- cat file| sed ... file1
- echo $variable| sed ... |grep xy
- if [ `echo $xy|sed ...` = blabla bla ]; then ...

The first sed expression is missing //. Correcting that:
sed -i -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//' test.txt
sed: lstat: No such file or directory
Yeah, I noticed the missing // in the first regexp, but only
