Modifiers

After the optional word designator, you can add a sequence of one or
more of the following modifiers, each preceded by a `:'.
`h'
     Remove a trailing pathname component, leaving only the head.
`t'
     Remove all leading  pathname  components, leaving the tail.
`r'
     Remove a trailing suffix of the form `.SUFFIX', leaving the
     basename.
`e'
     Remove all but the trailing suffix.
`p'
     Print the new command but do not execute it.
`s/OLD/NEW/'
     Substitute NEW for the first occurrence of OLD in the event line.
     Any delimiter may be used in place of `/'.  The delimiter may be
     quoted in OLD and NEW with a single backslash.  If `&' appears in
     NEW, it is replaced by OLD.  A single backslash will quote the
     `&'.  The final delimiter is optional if it is the last character
     on the input line.
`&'
     Repeat the previous substitution.
`g'
     Cause changes to be applied over the entire event line.  Used in
     conjunction with `s', as in `gs/OLD/NEW/', or with `&'.
