touch -- touch a file's last-mod date, backup bit, invisible bit, or
|
|
disable bit
|
|
|
|
syntax: touch <pathname> [-b y|n] [-d y|n] [-i y|n]
|
|
|
|
ex: touch myfile
|
|
touch =:bin -iy
|
|
touch ?:cda -dn
|
|
touch ? -bn
|
|
|
|
'touch' with no options sets a file's modification date/time to the
|
|
current date and time without actually modifying the file's contents.
|
|
Wildcards are allowed.
|
|
|
|
This is intended for use with recently-created files that, for some
|
|
reason, are not properly date- and time-stamped. (Some DOS 3.3-to-
|
|
ProDOS conversion programs, for example, stamp files with an invalid
|
|
date and time.)
|
|
|
|
The -b option lets you set or clear the "needs backup" bit on a
|
|
file. Use -by to set the bit or -bn to clear it. See also 'copy',
|
|
'update', 'cat', and 'ffind'.
|
|
|
|
The -i option lets you set or clear a file's "invisible" bit.
|
|
Invisible files don't show up in Davex catalog listings unless the
|
|
catalog command's -i option is used. The "invisible" bit has been
|
|
recently defined by Apple, and other programs may or may not pay
|
|
attention to the invisibility of a file.
|
|
|
|
The -d option lets you ENABLE or DISABLE certain types of Apple IIgs
|
|
files. A disabled file is not loaded automatically at boot time.
|
|
The filetypes that can be disabled are $B6 (permanent init file), $B7
|
|
(temporary init file), $B8 (new desk accessory), $B9 (classic desk
|
|
accessory), $BB (driver), $BC (generic load file), and $BD (GS/OS file
|
|
system translator). [Bit 15 of the auxiliary type for these filetypes
|
|
is the disable bit.]
