22.1.3 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.

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 `&'.
