9.3.3 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.
q
Quote the substituted words, escaping further substitutions.
x
Quote the substituted words as with 'q', but break into words at spaces, tabs, and newlines.
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 '&'.
