Bug ID: 293071
Summary: bsdtar -s pattern does not support delimiter quoting
Product: Base System
Version: 16.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]

I tried to add a prefix for a tarball. bsdtar has an option -s pattern.
-s pattern
Modify file or archive member names according to pattern. The
pattern has the format /old/new/[bghHprRsS] where old is a basic
regular expression, new is the replacement string of the matched
part, and the optional trailing letters modify how the
replacement is handled
It works well except if I include a slash:
touch a.c b.c
bsdtar -cvf c.tar -s '/^/foobar/\/' a.c b.c
bsdtar: Invalid replacement flag /
After some trial and error I find out that you can use other delimiters, as '|'
or '#'
$ bsdtar -cvf c.tar -s '|^|foobar/|' a.c b.c
a foobar/a.c
a foobar/b.c
I don't know if this is intentional or worth fixing. At least we should
document the current behaviour in the manual page, and add an example.
E.g.:
---------------------
Note: you cannot quote the / delimiter. In that case use an other characters as
'|'
bsdtar -cvf c.tar -s '|^|new-dir/|' a.c b.c
