`touch -p a/b/c/d/e` will now be the same as running: `mkdir -p a/b/c/d && touch a/b/c/d/e`.

Default behavior remains the same. --- src/touch.c | 40 +++++++++++++++++++++++++++++++++++++++- 1 file changed, 39 insertions(+), 1 deletion(-) diff --git a/src/touch.c b/src/touch.c index 21c247d0b..543f92b41 100644 --- a/src/touch.c +++ b/src/touch.c @@ -28,10 +28,12 @@ #include "die.h" #include "error.h" #include "fd-reopen.h" +#include "mkancesdirs.h" #include "parse-datetime.h" #include "posixtm.h" #include "posixver.h" #include "quote.h" +#include "savewd.h" #include "stat-time.h" #include "utimens.h" @@ -55,6 +57,9 @@ static int change_times; /* (-c) If true, don't create if not already there. */ static bool no_create; +/* (-p) If true, create directories if not already there. */ +static bool create_dirs; + /* (-r) If true, use times from a reference file. */ static bool use_ref; @@ -88,6 +93,7 @@ static struct option const longopts[] = {"date", required_argument, NULL, 'd'}, {"reference", required_argument, NULL, 'r'}, {"no-dereference", no_argument, NULL, 'h'}, + {"create-dirs", no_argument, NULL, 'p'}, {GETOPT_HELP_OPTION_DECL}, {GETOPT_VERSION_OPTION_DECL}, {NULL, 0, NULL, 0} @@ -116,6 +122,14 @@ get_reldate (struct timespec *result, die (EXIT_FAILURE, 0, _("invalid date format %s"), quote (flex_date)); } +/* Create directory, called by mkancesdirs(). */ + +static int +make_dir(char const * file, char const * component, void * arg) +{ + return mkdir(component, S_IRWXU | S_IRGRP | S_IXGRP | S_IROTH | S_IXOTH); +} + /* Update the time of file FILE according to the options given.
