Use sed to delete all leading/following blank spaces in a text file
perl -lape 's/^\s+|\s+$//g'
Honestly, I know perl regexps the best, so I find perl -lape
much easier to use than sed -e
.
Also, to answer the original question, you can have sed execute multiple operations like this:
sed -e 's/something/something else/' -e 's/another substitution/another replacement/'
Apparently you can also put the two substitutions in one string and separate them with a semicolon, as indicated in another answer.
